I INTERRACIAL RELATIONSHIPS AS CRIMINAL VICE

During the Progressive Era, Illinois’s state laws contained no provisions about interracial marriage. But this had not always been in the case. In 1829, Illinois passed a statute prohibiting the marriage between white and “colored” persons, making them “null and void in law” and allowing violators to be whipped or imprisoned.Footnote ⁵ Such statutes were commonplace leading up to the Civil War. They restricted the definition of a lawful, moral marriage and the benefits that flowed from it, like citizenship rights and property inheritance (Pascoe Reference Pascoe2009, 21, 27). Although their precise language differed, the statutes all had one feature in common: they restricted white people from marrying individuals of other races while allowing individuals of different minority groups to marry freely (120).

In 1871, Illinois repealed its ban on interracial marriage. The repeal came during a wave of similar repeals at the state level in the years following the Civil War (Pascoe Reference Pascoe2009, 40). Although some state statutes restricting interracial marriage were struck down in state courts as unconstitutional, other states, like Illinois, repealed their statutes, perhaps in part to avoid any constitutional controversy (40).Footnote ⁶ And yet, even without a state statute criminalizing interracial relationships, interracial couples in Progressive-Era Chicago still faced scrutiny from police and sometimes punishment from the courts for their legal union. As Chicago politicians and social reformers became focused on taming the perceived rise of “vice” in the city, interracial intimacy became wrapped up in the crusade to police social and moral norms.

During the Progressive Era, Chicago’s reformers developed an obsession with the concept of “vice,” an amorphous and illusive term that became a moniker for the city’s anxieties about sexuality, modernity, crime, and deviance. In 1910, the Chicago City Council created the Vice Commission, a group of thirty city leaders tasked with studying the problem of vice in the city and offering solutions (Chicago Vice Commission 1911, 5–6). The resulting report, The Social Evil in Chicago, provides a glimpse into what exactly “vice” meant, at least to this group of doctors, religious leaders, academics, and judges. The report is first and foremost about prostitution, seen as a perverse symptom of the fraying of traditional marriage. The report attributes rise in “sexual vice” to a rise in divorce, in turn attributed to “unhappy marriages” between people who are “degenerate” (41–42).Footnote ⁷

The Social Evil presents a narrative of the typical pathway into a life of vice. First, modern urban entertainment, like vaudeville shows, served as the gateway to prostitution (Chicago Vice Commission 1911, 125–26). With prostitution came “attendant vices,” which were the immoral practices of women drawn into prostitution—and the men who utilized their services—like drinking, drug use, and gambling (45). According to the Commission, “[t]he whole tendency of modern life” placed a “greater strain on the nervous system” of men and women, so that they “cannot but help, to a great extent, develop considerable eroticism” (199). The writers of The Social Evil feared that modernity itself produced the problem of sexual vice.

With a perceived rise in vice came a strong desire to control it.Footnote ⁸ Chicago’s Police Department and Municipal Court System deployed a set of low-level, open-ended criminal charges, which I call morals law, to crackdown on vice. These crimes included vagrancy,Footnote ⁹ disorderly conduct,Footnote ¹⁰ adultery,Footnote ¹¹ fornication, and prostitution offenses.Footnote ¹²

Morals law criminalized certain actions that were considered immoral, like begging or bringing a woman across state lines for prostitution. But the statutes also criminalized attributes. It was a crime to be “lewd, wanton, or lascivious,” and “idle and dissolute,” “disorderly,” or “indecent.” Today, these offenses—particularly those including subjective adjectival terms as criminal “acts”—might well be found unconstitutionally vague.Footnote ¹³ But at the time, there was no recognized constitutional limit on what kind of conduct a state could criminalize. Therefore, Illinois and Chicago were able to expand the arsenal of statutory offenses like these under the general state police power.Footnote ¹⁴

During the Progressive Era, the police power was seen as an integral part of “well-ordered society,” giving state governments “charged with the duty of conserving the safety” of its people the right and responsibility to pass reasonable regulations to promote health and welfare.Footnote ¹⁵ The maintenance of moral standards was seen as a part of public health, and a central purpose of what Ernst Freund called “[c]riminal justice, the proprietary action of the state, and the police power” (Freund Reference Freund1907, 7).

Along with an expanded arsenal of crimes came a new, modern municipal court system in 1907.Footnote ¹⁶ The city previously had relied on justices of the peace to administer justice in low-level criminal cases (Willrich Reference Willrich2003, 3, 9). These justices, who typically had little formal legal education, worked from a patchwork of decentralized “justice shops” throughout the city and relied on the payment of direct fees for their livelihood (8–9). Chicago’s Municipal Court system represented a shift toward the centralization and professionalization of the city’s legal system (47). The pages of the Court’s formal Annual Reports tell a story of efficient disposal of state and city offenses at Municipal Court branches across the city.Footnote ¹⁷

Beyond simply enforcing the law, leaders of the Municipal Court were in direct conversation with the Illinois State Legislature and the Chicago City Council to shape the law to their liking. The Court lobbied the City Council to make its vagrancy law operative, to pass an adult probation law, and to create a farm colony for “mentally defective” criminals.Footnote ¹⁸ In 1915, Chief Justice Harry Olson and other court leaders worked with social activists to pass the Kate Adams Law, which “made it a misdemeanor to be an ‘inmate’ of a ‘house of ill-fame’ … or to solicit in the city,” shifting prostitution from a fine-only offense to a crime punishable through jail or probation (Willrich Reference Willrich2003, 185). The Court thus became an active player in shaping the contours of the state’s power to regulate the moral health of its people, giving itself more discretion in the process.Footnote ¹⁹

In 1913, the city created a new specialized branch of the court system, the Morals Court, that would be authorized to hear criminal offenses “tending to debauch the public morals.”Footnote ²⁰ In his announcement of the Morals Court, Chief Justice Olson explained that its purpose was to eliminate the slums by eliminating the people who inhabited them. Olson believed that the city had to “start with the question of marriage of physically and mentally unfit persons” through “more drastic and uniform marriage laws” (Chicago Daily Tribune 1913a, 4). The Morals Court’s main target was the prostitution running rampant on the city’s South Side.Footnote ²¹ But lurking in the background was Olson’s broader goal: using morals law to regulate the institution of marriage, allowing “good” marriages to flourish while ferreting out “bad” marriages that produced what he believed were mentally deficient offspring. Olson was a eugenicist and promoted his eugenical theories on the bench (Laughlin Reference Laughlin1922, v–vi). In service of his eugenicist project, Olson also pushed for the appointment of Dr. Harry Hamilton Laughlin, a central figure in the movement to legalize eugenical sterilization, to the court.Footnote ²²

This web of vice control and expanding state power inevitably caught many interracial couples. For instance, in 1923, William Gray, a Black man, was arrested just outside the Morals Court when a police officer witnessed him take the arm of Violette Laue, a white woman (Chicago Defender 1923a). The police charged him with disorderly conduct. According to an article in the Chicago Defender, Morals Court staff informed Mr. Gray that “they would see to it that he was severely punished for his conduct in leaving the court room with a white girl” (1923a, 4). Mr. Gray was able to hire a defense attorney, who argued that the Morals Court was prejudiced against his client and successfully requested a change of venue to another branch of the Municipal Court.Footnote ²³

At Mr. Gray’s hearing, two individuals from the city’s health department testified against him, arguing that his actions—holding a white woman’s arm in public—constituted disorderly conduct, which was defined under state law as “open lewdness … tending to debauch the public morals.”Footnote ²⁴ The judge dismissed the case, finding the city had failed to prove the defendant acted in a disorderly manner. Mr. Gray’s interaction with the city’s legal system highlights the broad discretion state actors had to prosecute individuals for violating a perceived group norm.

Legally married interracial couples in the city faced similar scrutiny when they appeared together in public. In 1924, a police officer questioned Mr. and Mrs. Parson, an interracial married couple who were taking photographs of Lake Michigan. The officer asked if they were legally married. The couple explained that they had been married for three years. Not believing their story, the officer followed them all the way home from the lake (Chicago Defender 1924).

In another instance, a friendly interaction between a white woman and a Black man on a city sidewalk led to interrogation, warrantless search, and arrest. When four police officers witnessed Ethel Stokes, a white, Jewish woman, stop on a street corner to “have a moment’s chat” with her friend, a Black man, they arrested her on the spot and brought her to the police station to be questioned (Chicago Defender 1923b, 3). The officers demanded an objective answer about her race. According to Ms. Stokes, the officers asked her, “What are you, white or Colored?” and interrogated her on her marriage. Upon learning she was married to a Black man, the officers questioned why she didn’t marry a Jewish man or a “Gentile” (3). After the interrogation, the officers took her to her home and forced her to produce her marriage certificate to prove the legality of her relationship. When her husband arrived, “he was promptly arrested and locked up” (3). The newspaper article detailing Ms. Stokes’s interaction with the police does not explain what charge was brought against her husband, but it’s certainly possible that he was arrested on a morals violation, perhaps disorderly conduct like Mr. Gray or fornication like Mr. Wilburn, two other Black men who dared to be in consensual relationships with white women.

The Chicago Police demanded that Ms. Stokes tell them whether she was “white” or “colored.” If she had told the officers she was “colored” then, presumably, they would not have questioned the legality of her relationship. But because she identified herself as “white,” the officers inverted her relationship into something presumed unlawful. The historical record does not allow us to know how common these interactions between the police, courts, and interracial couples were during this era. It’s not even clear how many interracial couples lived in Chicago, as these statistics were not recorded (Roberts Reference Roberts1940, 11). Yet the record shows that these interactions happened, and that by playing out day after day, they embedded interracial intimacy within the meaning of morals law, transposing lawful marriage into an unlawful, immoral form of vice. And by forcing individuals to place themselves in clear-cut, racial boxes, such interactions were making the meaning of race itself.

II REGULATING INTERRACIAL SPACE IN CHICAGO

The same impulse to criminalize interracial sexuality played out on a larger scale in the city’s sensational raids of “black and tan” clubs and disorderly hotels.Footnote ²⁵ These spaces blurred the unofficial yet sharp boundaries between Black and white space in the city. Police raids of these businesses transformed them into inherently unlawful spaces, signaling that interracial intimacy would not be tolerated in public.

In 1930, a white man named Charles McDonald (Reference McDonald1930, 14) wrote a letter to the editor of the Chicago Defender about interracial relationships, stating “I for one am for it.” But he lamented that as a “sincere white person,” he had no chance to meet a “decent colored person” in the city. He implored the paper to publish the location of spaces in the city where white and Black residents could meet each other. Mr. McDonald’s letter frames the problem of segregation in Chicago as one created and easily remedied by individual choice, when in reality, the geographic segregation in Chicago was the entrenched result of racially charged violence and conscious decisions from city leadership to crackdown on interracial socialization as a crime.

In 1922, the Chicago Commission on Race Relations, which had been tasked with exploring the causes of the bloody 1919 Chicago Race Riot, published a comprehensive report entitled The Negro in Chicago. The report provides a picture of the racial boundaries drawn in the city during the Progressive Era. The Commission explained that although there was no Jim Crow in Chicago, “unofficial discrimination … frequently creeps in” (277). This unofficial discrimination often manifested in the form of divided physical spaces. At Lake Michigan, there were no signs to cordon off areas for white bathers and Black bathers, but city police officers would nonetheless advise Black residents not to cross the invisible line between the beaches (277–78). Black residents in the city could legally patronize any business or restaurant, but white-owned businesses frequently turned them away (310–11, 320). White residents complained to the commission that recent Black migrants from the South “sit all over the cars,” rather than remain in the back (302). Even the Morals Court was segregated, with one attorney for Black defendants and another for white.Footnote ²⁶

Black Chicagoans were, by and large, forced to live in a specific area of the city. As the Black population in the city grew during the Great Migration, Black residents were confined to an area on Chicago’s South Side known as the “Black Belt” or “Bronzeville.”Footnote ²⁷ Within the area, which was roughly seven miles long and one mile wide, a “quarter-million colored people were packed on top of one another” (Wilkerson Reference Wilkerson2010, 268). New migrants arrived to already overcrowded apartments, but there was no room to grow; attempts to rent or buy apartments outside of this tightly packed neighborhood were met with death threats, violence, and bombings from white residents (272).Footnote ²⁸

Bronzeville was proximate to the city’s old vice district, the Levee, and after the police shut the Levee down in 1914, crime swiftly swept into the neighborhood (Chicago Commission on Race Relations 1922, 93, 343).Footnote ²⁹ At the beginning of the twentieth century, the Chicago Police Department, corrupted by organized crime, turned a blind eye to illegal vice so long as it stayed contained within Black neighborhoods.Footnote ³⁰ Where migrants settled, vice quickly followed, looking for places to operate undisturbed by the law (Muhammad Reference Muhammad2010, 343). The Chicago Commission on Race Relations concluded that Black residents tended to live in vice districts for reasons outside of their control; unwelcome in white neighborhoods, lacking political representation, and working for low wages, they had little power to fight back (Chicago Commission on Race Relations 1922, 344). Although the proximity to vice was outside of Black residents’ control, it reinforced a narrative in white society that Black migrants were inherently immoral, unfit for city life, and prone to criminality. This narrative built upon a long-standing stereotype that painted Black men as “constitutionally indolent, voluptuous, and prone to vice” (Muhammad Reference Muhammad2010, 20–21).

During the Progressive Era, many white reformers in northern cities put money toward funding Black education in southern states and condemned lynch mobs as savage and unlawful (Muhammad Reference Muhammad2010, 27–28). And yet, the general attitude of these same reformers to Black residents of their own cities was one of “hesitation and withdrawal,” leaving recent migrants to fend for themselves without robust support from social services (28).Footnote ³¹ This ambivalence to local Black communities was what sociologist Gunnar Myrdal called the “Northern Paradox” in his 1944 study on race relations (Myrdal Reference Myrdal1944, 1010). White, northern Progressives were quick to condemn the overt, violent discrimination in the Jim Crow South while simultaneously perpetuating more subtle forms of discrimination and intolerance at home.Footnote ³²

At first, this apathy from Progressive, white social reformers in Chicago led to inaction. Crime persisted in Bronzeville virtually unchecked, circularly confirming to many white people their preconceived, racist belief that Black migrants were inherently immoral. Reformers simply placed the onus on the community itself to quash vice in Bronzeville; a bailiff in the Morals Court once remarked to a journalist, “it [is] a shame that the Colored people did not do something” about it (Chicago Defender 1917, 1). In reality, Black community leaders worked hard to better their own neighborhood and drew frequent attention to the indifference of the city’s white leaders, who did not seem to care about ridding Black communities of vice (Blair Reference Blair2010, 188–90).

When, in the 1920s, the Chicago Police Department began taking a more active role in cracking down on vice, it took little account of the voices of those who actually lived in Bronzeville.Footnote ³³ The crime problem was instead framed as a blight on the city’s overall image. Police leadership like Lieutenant Michael W. Delaney remarked, “Cabarets never close. Gambling is wide open. Women walk the streets. Every statute enacted has been violated with impunity. We must clean up” (Kingallen Reference Kingallen1920, 13). By 1923, Police Chief Fitzmorris went as far as ordering a police officer to be stationed at the front and rear of every known disorderly house in the city to make sweeping arrests (Chicago Daily Tribune 1923b).Footnote ³⁴

The police employed dragnet tactics in Bronzeville, conducting large-scale, sensational vice raids that pulled patrons of dance halls, disorderly houses, and black and tan clubs into police wagons, jail cells, and courtrooms. And the police often failed to exercise basic tenets of due process along the way.Footnote ³⁵ By simply existing in a location that was considered “unlawful,” a person faced the threat of arrest, conviction, and punishment.

One of the major targets of these police raids were the black and tan clubs of the city where Black and white people socialized together, often coupled with other emblems of Prohibition-era vice, like drinking, gambling, and dancing (Chicago Commission on Race Relations 1922, 323–24). In newspaper accounts describing a raucous night in these clubs, the journalists described the “intermingling of races,” with people of “all the tints of the racial rainbow, black and tan and white, dancing, drinking, and singing” as the most scandalous detail (323–24).Footnote ³⁶ These clubs were an integral part of “slumming,” where middle-class white men sought a night of illicit, exotic fun outside the bounds of civilized morality (Blair Reference Blair2010, 217).

During the 1920s, various Chicago mayors and chiefs of police made it a governmental priority to shut down interracial spaces through a variety of techniques—divesting the clubs of city licenses, arresting their owners, and conducting late-night raids that became front-page news.Footnote ³⁷ In 1923, Mayor William Dever revoked the licenses of “six of Chicago’s most notorious black and tan cafes,” stating that he would “not permit ‘rotten cafes’ to undermine the public health and morals” in the city (Chicago Daily Tribune 1923a, 4). That same year, the police conducted a late-night raid of two famous disorderly hotels: the Vincennes and LaBelle. In a sensational report in the Pittsburgh Courier, a reporter described officers emerging “accompanied by a select company of attractive white girls and their colored companions and white libertines with their gay, senseless colored men,” all of whom were charged with disorderly conduct (1923, 2).

According to testimony from city leaders printed in newspapers and reports at the time, the purpose of these raids was to clean up the city from all kinds of vice; the sensual dancing between Black and white individuals was only one element of a broader vice culture that needed to be stopped (Kingallen, Reference Kingallen1920). But the raids on black and tan clubs also grew out of the sensationalized narrative known as “white slavery”–the idea in Progressive-Era popular culture that innocent white women were being lured to the big city and corrupted into prostitution by “dark” immigrants and Black men.Footnote ³⁸

In 1907, George Kibbe Turner published an influential article entitled The City of Chicago: A Study of the Great Immoralities, in which he claimed there was a “well organized traffic in women, a very real white slave market” in the city (Donavan Reference Donavan2006, 61). He blamed the rise in crime, including the trafficking of these innocent white women, on the wave of recent European immigrants and on “the vicious negro from the countryside of the South” whom he claimed “furnish an alarming volume of savage crime” (61). Authors like Turner, whose works were immensely popular at the time, overtly linked tackling the problem of vice with the higher purpose of preserving white purity (56–88).

In a city with sharp delineations between Black and white space, socialization between two races broke down the norm of separation. Black and tan clubs became frequent targets of police and court scrutiny as perceived sites of immorality that threatened white purity. During World War I, the vice raid also became a tool of public health necessity, when Illinois greatly expanded the ability of the Chicago Police and the Municipal Court to detain and test women to combat the threat of venereal disease.Footnote ³⁹

Whether framed as a tool to quash vice, protect white purity, or combat venereal disease, vice raids brought vast numbers of defendants before the Morals Court. It’s clear from the pages of the Court’s annual reports that its leaders believed that while visible, public displays of immorality deserved to be restricted, some men and women could do what they wanted behind closed doors. The Municipal Court’s Tenth and Eleventh Annual Report states that when “mature men and women” were arrested in “raids on questionable hotels” on charges of fornication, it did little good to punish them, as “[t]he large majority of this class of offenders are, in other respects, law abiding citizens.”Footnote ⁴⁰ This report suggests that the Morals Court was chiefly focused on punishing public immorality.

Although vice raids were initially used as a tool to combat public immorality, city officials also raided the private homes of interracial couples. According to a 1924 Pittsburgh Courier article, the Chicago police were “conducting wholesale raids without reason on the homes” of families in Bronzeville.Footnote ⁴¹ Officers would break into homes under the pretext of making vice arrests without search warrants, after which bondsmen would pay them for the heads brought into the station. Police flouted the rights of suspects for the sake of cleaning up the city (or for self-serving, corrupt reasons), bringing them into the Morals Court where they could be severely punished at the judge’s discretion (Muhammad Reference Muhammad2010, 251). Bronzeville was the neighborhood where interracial couples most often lived in Chicago. Because they faced violence from white neighbors, Bronzeville provided them greater safety, but it also subjected them to greater police scrutiny (Roberts Reference Roberts1940, 91–92).Footnote ⁴²

The police’s vice raids—both public and private—created negative consequences for interracial couples in the city. The raids brought a number of these couples before the Morals Court, which reinforced a narrative that interracial couples were inherently immoral. And, as the next section will show, the punishments that a low-level morals charge could bring could be quite intrusive and aggressive.

III PUNISHING INTERRACIAL INTIMACY

The Morals Court had jurisdiction over only low-level morals offenses that were, according to the statute books, punishable only by small fines or a jail sentence under a year.Footnote ⁴³ But two aspects of the Municipal Court system vastly increased the discretion of Morals Court judges to issue additional, and often more intrusive, punishments for these low-level crimes: the passage of the Adult Probation Act in 1911 and the creation of a Psychopathic Laboratory in 1914. By coupling low-level, open-ended charges with a menu of options for punishment, the Morals Court had an immense amount of discretion to restrict individual liberty.

From the Municipal Court’s inception, judges had lobbied the Legislature to pass an adult probation bill.Footnote ⁴⁴ The Adult Probation Act, passed in 1911, gave judges in the Municipal Court the discretion to place first-time offenders of misdemeanor violations on probation for up to one year (Willrich Reference Willrich2003, 93). The Court’s probation officers had broad discretion to surveil probationers, investigating “personal characteristics, habits, associations, and … conduct” (94). Under the power granted by the Adult Probation Act, the Morals Court surveilled citizens in droves, increasing the intrusion of the state into daily life. For instance, during a large-scale vice raid of a disorderly house in 1917, Judge Fisher put all the women picked up by police under the surveillance of Mrs. Jessie Thomas, a probation officer (Chicago Defender 1917). Whereas a charge of disorderly conduct once required simply paying a fine, it could now lead to a full year under the eye of a reform-minded probation officer, patrolling for evidence of further indecency or immorality. Any small transgression could lead to more judicial scrutiny and punishment.

The Morals Court gained even more discretion over punishment with the creation of the Psychopathic Laboratory in 1914 (Willrich Reference Willrich2003, 241–77). The Morals Court’s effort to control “vice” was just one arm of a broader Progressive project of using the law to control people considered “degenerate” through eugenics. The creation of the Psychopathic Laboratory represented the apex of the Municipal Court’s commitment to codifying eugenical ideas into the city’s legal system.

The eugenics movement in the United States gained prominence in the late nineteenth century, as American social reformers and scientists embraced the idea that heredity was the primary predictor of human intelligence and morality (Carlson Reference Carlson and Paul2011, 12–14). Eugenicists advocated for three major policies to combat social problems like crime and poverty: categorization, segregation, and in some states, sterilization.Footnote ⁴⁵ Progressive reformers believed that through physical and psychological examination, negative traits could be isolated and bred out of the human race through negative means (restricting reproduction) and positive means (promoting good marriages).Footnote ⁴⁶ Eugenicists isolated “bad traits” by collecting data, using intelligence tests, and taking detailed family histories to fit individuals along a spectrum from normal to abnormal.

As Chicago professionalized and expanded its Municipal Court system, the Illinois State Legislature expanded the number of state “charitable institutions” and the state funding they received.Footnote ⁴⁷ These charitable institutions, like the Northern Hospital for the Insane and the Asylum for Insane Criminals at Chester, were physically segregated spaces for people thought to suffer from certain “medical” diagnoses, like feeble-mindedness,Footnote ⁴⁸ dementia praecox,Footnote ⁴⁹ or insanity. And the list of people who were thought to be susceptible to these conditions included a shockingly broad swath of the population, ranging from people with alleged physical and mental disabilities, mothers of illegitimate children, alcoholics, criminals, and the poor.

The Morals Court sought to study its defendants “scientifically,” collecting data on offenders to draw conclusions about the root causes of immorality (Chicago Daily Tribune 1914a).Footnote ⁵⁰ The Court employed a female physician, Dr. Anna Dwyer, to examine female defendants and locate commonalities between them. In the first year of the Court’s operation, Dr. Dwyer found that over half of the 639 female offenders she examined were “mentally deficient,” possessing a “subnormal” level of intelligence.Footnote ⁵¹ Court leaders used her findings to justify a shift in sentencing from retribution to reform.Footnote ⁵² Practically speaking, this meant that judges in the Morals Court came to see fines as a “misconceived remedy” for prostitution and other vice infractions because so many criminal defendants were “feeble-minded” individuals “obeying impulses which they [could not] control.”Footnote ⁵³ Instead, a judge might choose to sentence an individual to probation, allowing a state official to surveil and attempt to reform bad behavior. For a smaller subset of individuals perceived by the court as too morally and mentally deficient to be capable of reform, judges often concluded they must be isolated from society and permanently controlled by the state.

In 1914, Municipal Court leaders created the Psychopathic Laboratory, a special branch of the court devoted to the scientific study of defendants.Footnote ⁵⁴ The lab put the goals of the eugenics movement into practice. It amassed data on the psychological and physical make-up of criminals, using questionnaires, a drawing test, and the Binet-Simon intelligence scale.Footnote ⁵⁵ Relying on that data, the lab identified individuals to isolate from society in sex-segregated institutions that restricted their ability to reproduce.Footnote ⁵⁶

The Psychopathic Laboratory’s “study” of criminal defendants led to a handful of common diagnoses with labels like insanity, dementia praecox, and most commonly, feeble-minded. At the time, these were considered medical terms with legal significance. Labeling someone “feeble-minded” had power. But it was also an invention, a fiction, an unreality. It was a catch-all term for people who, according to a physician of the era Walter Fernald, ranged from slightly “below the normal standard of intelligence” to “the profound idiot” (Lombardo Reference Lombardo2022, 15). In the most infamous case about state control of the feeble-minded, Buck v. Bell, the Supreme Court’s cursory three-page opinion never even defined the term.Footnote ⁵⁷ “Feeble-minded” had a shared meaning that felt obvious and natural to reformers, generally accepted as an immutable and biological characteristic, despite its breadth and ambiguity.

Once diagnosed by the lab, the Municipal Court had legal power to commit defendants to state institutions, even if they were arrested on a minor charge. Morals Court judges could refer any defendant to the Psychopathic Laboratory. According to the head of the lab, nearly 90 percent of the women referred from the Morals Court were subnormal in some manner.Footnote ⁵⁸ If the doctors determined the individual to be mentally deficient, they could recommend commitment or initiate a separate court action to force commitment.

Admission into state hospitals could thus be court-ordered and potentially indefinite. If an individual was “feeble-minded,” state law permitted “any reputable citizen of the State” to file a petition in court to determine if the individual was “dangerous to the welfare of the community.”Footnote ⁵⁹ If the court found an individual was feeble-minded and dangerous, it could either appoint a guardian or order the person be sent to a state or state-licensed private institution.Footnote ⁶⁰ Once admitted a patient could only be discharged when a separate court action found it to be justified based on considerations of the welfare of the individual and his community.Footnote ⁶¹

Returning to the story of Mr. Gray, the Black man arrested for holding a white woman’s arm in the lobby outside of the Morals Court, the facts of his case demonstrate the danger of a low-level charge for individuals in interracial relationships. Although Mr. Gray’s case was dismissed, it’s easy to see how it could have come out differently. A charge of disorderly conduct could lead to a year in prison, a year under the surveillance of a probation officer, or the potential for indefinite commitment in a state mental institution. Although there is nothing in the report of Mr. Gray’s case to indicate that he possessed below average intelligence, the city’s decision to bring two health department officials to his hearing stands out as a potential attempt to argue for his commitment, as state law required the testimony of two physicians to commit someone against their will.Footnote ⁶² All those consequences could flow from the judgment of an individual police officer that a Black man holding the arm of his white companion tended to debauch the public morals.

Some of the interracial couples brought before the Morals Court were not as lucky as Mr. Gray. Many were no doubt referred to the Psychopathic Laboratory, where race scientists then pathologized people in interracial relationships as biologically subnormal and hypersexual. The Municipal Court’s Tenth and Eleventh Annual Report, published in 1917, provides the most detailed window into the lab’s work. According to the report, a total of 947 cases from the Morals Court had been referred to the lab since 1914.Footnote ⁶³

The report breaks down 701 of the 947 total cases referred to the lab from the Morals Court.Footnote ⁶⁴ It delineates cases based on mental diagnoses along a spectrum from normal to abnormal, providing a snapshots into the specific facts of different cases within each category. For instance, under the category “Low Grade Sociopaths,” the report lists one case: “[c]ase, age 31, dementia praecox; four arrests in Morals Court and three previous arrests, six as an inmate of disorderly house; one for burglary.”Footnote ⁶⁵ These case snapshots all share common elements: age, mental diagnosis, and crime.

Within this report, nine case snapshots reference interracial relationships. Several explain that the defendant was physically near or living with a person of another race when arrested. For instance, one such case description describes a woman as “age 24, dementia praecox, white; lives with a colored man.”Footnote ⁶⁶ Another woman is described as “married to white man with whom she has a little girl, age seven,” but found “consorting with a Chinaman.”Footnote ⁶⁷ Yet another reads, “age 20, psychopathic, alcoholic, colored; arrested with a white man.”Footnote ⁶⁸ Other defendants brought into the lab are described as “white; was living with a colored man,” “psychopathic white man, … arrested for living with negress,” “white: arrested in hotel with colored girl,” “colored; was with white woman in a raid.”Footnote ⁶⁹

Other case descriptions note that the defendant was married to a person of another race. A 21-year-old white woman who was diagnosed with “dementia praecox with moral defect” was described as having been “in reform school three years, was married to a colored man, deserted him, and now living with another colored man.”Footnote ⁷⁰ A 26-year-old woman, also diagnosed with “dementia praecox,” was described as “mental level 9.6 years, alcoholic, white, married to colored man”; her record also notes that she previously had “six arrests in Morals Court, soliciting and drinking.”Footnote ⁷¹ The most striking feature of these case snapshots is that they do not mention the crime that resulted in their referral to the Psychopathic Laboratory. Every other case snapshot identified the individual’s mental disorder and crime. For these people, instead of a description of their crime, the lab recorded the fact that they had a relationship with someone of another race.

The Psychopathic Laboratory was one aspect of a broader crusade of Municipal Court leaders like Chief Justice Olson and lab scientist Harry Laughlin to implement eugenical sterilization statutes across the country to further the goal of racial purity (Laughlin Reference Laughlin1922, vii). Within this eugenical program, interracial relationships were seen as both the symptom and the disease. Being “mixed stock” made you more likely to be degenerate, and one of the symptoms of degeneracy was hypersexuality, often characterized by an attraction to someone of the opposite race (364).

The Psychopathic Laboratory’s seminal report, Eugenical Sterilization in the United States, lauded individuals of “pure stock” while condemning those of “mixed stock” as mongrels “of an undesirable combination of characters” (364). Municipal Court leaders describe the problem of mixed-stock individuals under the same racist logic frequently deployed in southern courtrooms when adjudicating cases under “antimiscegenation” statutes. For instance, in a 1924 annual report, Harry Laughlin penned an essay called Human Heredity that describes the twenty-four chromosomes that “are the physical carriers of heredity,” which “they call the germplasm” or the “blood” of race stock.Footnote ⁷² An accompanying illustration (see Figure 1) entitled the Chromosomes of Man shows the twenty-four chromosomes of a white individual and a “Negro” individual creating a “Negro” offspring.Footnote ⁷³

This illustration suggests that the concept “mixed stock” that appears so frequently in the reports from the Court was a pseudoscientific manifestation of the one-drop rule, the idea that having any Black ancestors tainted blood and made a person not white (Jordan Reference Jordan2014).

In Eugenical Sterilization in the United States, Harry Laughlin and Harry Olson lauded the work of eugenicist Lothrop Stoddard, who made the connection between eugenics and interracial intimacy explicit (Laughlin Reference Laughlin1922, 323). In The Rising Tide of Color against White World-Supremacy, Stoddard warned of white race suicide, arguing that “in ethnic crossings, the negro strikingly displays his prepotency, for black blood, once entering a human stock, seems really never bred out again” (90). According to Stoddard, when individuals of different races had children, their offspring were “a walking chaos,” incapable of contributing meaningfully to society because of hereditary degeneracy (165–66).

Psychopathic Laboratory leaders not only believed interracial relationships were a cause of inferior, mixed-stock children but also saw interracial attraction as a sign of an individual’s moral and mental deficiency. At the time, one identified symptom of subnormal intelligence was hypersexuality. Those labeled as feeble-minded and dementia praecox were considered “sex delicts” who “show[ed] a fondness for carousing with the opposite sex.”Footnote ⁷⁴ And one clear indicator of hypersexuality was thought to be attraction to people of another race. Eugenicists believed, for example, that mentally deficient Black men had a propensity to be controlled by sexual desire for white women. In one of the Psychopathic Laboratory’s long-winded patient histories, a white woman named Alice Smith, diagnosed as feeble-minded, is described as growing up near Black families (Laughlin Reference Laughlin1922, 447–48). When her father grew violent, she and her siblings would “seek refuge among the negroes about the neighborhood.” This scandalous childhood closeness led to her having sex with a Black man, a critical factor in her eventual diagnosis as feeble-minded that led to her indefinite commitment in a mental institution.

Because much of the Municipal Court’s meticulous recordkeeping has been lost, there is no record of what happened to the specific individuals brought to the Psychopathic Laboratory, including those labeled by their interracial relationship. Most likely they were committed. Scattered among other annual reports, descriptions of the lab’s disposition of mentally deficient individuals paint a picture of swift institutionalization. Anyone found “to be insane, or definitely disordered mentally,” was sent to a “suitable place, public or private,” typically the Cook County Psychopathic Hospital.Footnote ⁷⁵ For those considered feeble-minded, the lab would send them to “the Lincoln State School and Colony.”Footnote ⁷⁶ Individuals singled out because of an interracial relationship would therefore be forced to spend some unspecified amount of time—perhaps the rest of their adult life—in a sex-segregated state institution.
