AIDES-PRÉPARATEURS:

Chaltiel was the aide-préparateur during 1906–8; in 1909, he was joined in this position by Jannot. From 1909, the position was vacant, until five people—including Lafond, Roussel, and Huret, who later became préparateurs and remained at the Institute throughout Nicolle's tenure—were hired to fill the position. The number of aide-préparateurs varied between four and six in the years 1919–35.
