Abstract

The reorganization of the astronomical community during the late nineteenth and early twentieth centuries, due to the rise of astrophysics, was seen by some scientists as an opportunity to join an international community of prestigious researchers. This was the case of astronomers such as Josep Comas i Solà, who publicly argued with Eugène Michel Antoniadi during the first decades of the twentieth century about the veracity of astronomical observations and theoretical conclusions on Mars and Jupiter. Their priority claims and public disputes have to be understood in a new context that provided an exceptional opportunity for amateur and professional astronomers both to play an active role in the most interesting scientific debates of these years and to gain prestige, legitimacy and power.

23 As Comas i Solà wrote, ‘Après la galante critique de M. Antoniadi par rapport à mes observations de Mars faites en 1894 (avec une lunette de 108mm), critique publiée dans une note du “Sixth Report of the Section for the Observation of Mars”, page 75, et après ma protestation contre cette critique, protestation publiée dans le “Journal of the British Astronomical Association”, page 438 du nº8 de l'année courante, M. Antoniadi explique la raison de sa critique à la page 47 du “Seventh Report of the Section”. M. Antoniadi dit, simplement, qu'avec un 4½ pouces il était impossible de voir, en 1894, le Lac du Phoenix, obscur, défini et rougeâtre, puisque le grand Dawes ne put jamais l'apercevoir auparavant avec un 8 pouces’.

28Il y a bien long-temps que j'ai remarqué un sentiment de jalousie à mon égard de M. Comas Solà. Ainsi, lorsque j'ai découvert l'aureole optique autour de la Nova Persei en 1901, découverte publiée sous les noms Flammarion et Antoniadi, comme ayant été faite a l'Observatoire de M. Flammarion, M. Comas Solà, dans son livre sur l'astronomie, a dit que c’était M. Flammarion qui avait découvert ce fait, sans mentionner mon nom … En éliminant mon nom, M. Comas Solà altère la vérité’.

30 Note that Lowell and others argued that the canals themselves were too small to be observed from the Earth and therefore observers saw wide bands of vegetation that ran alongside and were watered by the canals.

34 The Mars debate became especially lively during the 1890s at the British Astronomical Association, closely linked to the extraterrestrial-life debate and the idea that the canals could be the work of intelligent agents.

38 The popular historical interest in inhabited Mars has recently been revisited, emphasizing the strong links that astronomical narratives about the red planet had with geography and with the knowledge-production processes characteristic of this latter field.

42 For example, when Antoniadi was offered the chance to become the director of the Observatory of Athens, he was requested to present an honorary academic degree from a European university, which he could not obtain. Antoniadi to Raurich, 24 August 1910, SR, Ms 3943/2.

43J'ai aussi une formidable correspondance avec les principaux savants du monde, commençant le 21 septembre 1909, correspondance qui va bientôt briser toute résistance. La guerre avec Comas Solà va s'allumer en Angleterre’. Antoniadi to Raurich, 19 December 1909, SR, Ms 3943/2.

44 Antoniadi's reluctance to accept the results of Comas i Solà’s observations during the 1890s may be reasonable. In fact, as has recently been pointed out, several planetary observations reported from 1890 and 1894 by Comas i Solà were under the theoretical resolution limit of his telescope. See Oliver, J. Maria, Josep Comas Solà, observador visual, Sabadell: Agrupació Astronòmica de Sabadell, 2007Google Scholar. However, it is suggested here that Comas i Solà was able to make such observations because of his long experience as an astronomer – even when he may have not distinguished well-defined details because of the low image contrast.

45 ‘With their excellent 4¼-in. by Fraunhofer, Beer and Maedler saw no «canals» on Mars. Comas Solá, with a French glass (and such glasses are seldom good, unless coming from the Brothers Henry), saw 42 ‘canals’. But Beer and Maedler were much more skilled observers than Comas Solá, and their evidence seems decisive … For it would be absurd to believe that markings which eluded the eagle eye of Dawes with 8 inches could ever be seen by Comas Solá with 4¼ inches!’. Antoniadi to Raurich, 8 November 1910, SR, Ms 3943/2. Note that, despite playing important roles in similar disputes, atmospheric issues related to observational sites were not present in this controversy between Antoniadi and Comas i Solà.

53 As Lankford has pointed out, this debate achieved symbolic resolution in the 1910s, when most amateur astronomers, such as Theodore E.R. Phillips, recognized the immense value of large-aperture telescopes in the study of the planets. For a complete study of this controversy see Lankford, John, ‘Amateurs versus professionals: the controversy over telescope size in late Victorian science’, Isis (1981) 72, pp. 1128Google Scholar.

54 Antoniadi to Raurich, 8 November 1910, SR, Ms 3943/2. In fact, as has been previously suggested when dealing with the Astronomical Society of Barcelona, Raurich made no explicit mention of Comas i Solà in the articles he wrote acknowledging Antoniadi's discovery of the illusory character of the Martian canals. However, both in the specialized journals (like the Boletín de la Sociedad Astronómica de Barcelona) and in more general periodicals (such as Por esos mundos) where Raurich wrote on the topic, references to Comas i Solà were easily ascertained when he criticized those who observed Mars with telescopes of 108 mm aperture, like the one regularly employed by Comas i Solà for planetary observations. See, for example, Raurich, op. cit. (52).

55 A good example is Comas i Solà’s public lecture on 17 December 1909 at the Royal Academy of Science and Arts of Barcelona. See Historial del Academico J. Comas Sola, Archives of the Royal Academy of Science and Arts of Barcelona, Barcelona, Folder ‘Documentos Referentes al Académico’.

59 During the first decades of the twentieth century most Spanish governments adopted a regenerationist rhetoric – a legacy of nineteenth-century Spanish liberal ideas that spread, particularly after the Spanish–American War of 1898, throughout various sectors of Spanish society, through the press, universities, and the parliament. In general terms, regenerationists wished for a nationwide programme of public works to create the infrastructure needed for a modern economy. Regenerationism strongly influenced the political life of the country during these years, but the concept was finally emptied of meaning, and the word was absorbed by and included as part of the established political system.

65 ‘The most noteworthy incident in connection with recent studies of Jupiter is to be found in a very pronounced acceleration of motion in the great red spot … And this increase of velocity has been contemporary with the outbreak of a large, irregular or multiple marking of a dusky hue, in the same latitude of the planet … It seems a probable conjecture that the presence of the marking just referred to may have forced the red spot along at a more rapid rate than that which it exhibited in previous years’.

69 The idea of situating scientists in networks of trust was developed by constructivists (although in a slightly different way to that presented here) from Collins's claims that individuals’ knowledge must be acquired by contact with the relevant community rather than by transferring programmes of instruction.
