4-64. Émile Picard
Charles-Émile Picard (1856–1941) was the son of a silk-factory manager. He attended the École normale supérieure, and obtained the agrégation in mathematics in 1877. He was recruited by Paris Faculty of Science in 1878, and named Chargé de cours in differential and integral calculus the following year. In 1881, he married a daughter of Charles Hermite. In 1886, Picard was named to the chair of differential and integral calculus. Picard also lectured on mechanics at the École centrale des arts et manufactures from 1894. In 1897, upon the retirement of his father-in-law, Picard was named to the chair of analysis, which he held until his own retirement in 1931. From 1900, he also taught at the École normale supérieure de jeunes filles, in Sèvres.
Picard joined Poincaré in the geometry section of the Paris Academy of Sciences on 11 November, 1889, and was elected Perpetual Secretary of the Academy on 2 April, 1917. He was a member of the Bureau of Longitudes, and of the Académie française.11endnote: 1 Institut de France (1968, 436), Charle and Telkes (1989, 226).
