(b. Boston, Massachusetts, 28 August 1867; d. Cambridge, Massachusetts, 12 September 1918)

mathematics.

Maxime Bôcher was the son of Ferdinand Bôucher the first professor of modern languages at the Massachusetts Institute of Technology, and Caroline Little, of Boston. He entered Harvard in 1883, specializing in mathematics and natural science under W.E. Byerly, B.O. Pierce, and J. M. He was elected to phi Beta Kappa upon his graduation in 1888. Bôucher then went to Göttingen as a traveling fellow to audit the lectures of Felix Klein, Schönfiles, Schur, Schwarz, and Voigt. Encouraged by Klein, he wrote a tract that won the prize in a competition sponsored by the philosophical Faculty at Göttingen in 1891. It also served as his doctoral dissertation (1891), and was published as a book (1894) with an introduction by Klein.

In 1891 Bôcher returned to Harvard as an instructor in mathematics, and rose through the ranks to a professorship in 1904. In 1913 he was an exchange professor at the Sorbonne for a three-month period beginning in November.

He served the mathematical community unstintingly as a member of the editorial staff of the Annals of Mathematics in 1896–1900, 1901–1907, and 1911–1914; as vice-president, in 1902 and as president, in 1909 and 1910, of the American Mathematical Society; and as editor of the Society’s Transactions in 1908, 1909, and 1911–1913. Under Klein’s leadership as president of the international Commission on the Teaching of Mathematics, Bôucher served as chairman of the American Committee on Graduate Work in Universities, which published the report “Graduate Work in Mathematics in Universities and in Other Institutions of Like Grade in the United States” in the Bulletin of the U.S. Bureau of Education no. 6 (1911). He was an invited speaker at the St. Louis Congress of Mathematicians in 1904 and at the Fifth International Congress of Mathematicians, Cambridge, England, in 1912, where his paper dealt with boundary problems in one dimension.

Bôucher was a prolific contributor to mathematical journals on the theory of differential equations and related questions. His research topics included systems of linear differential equations of the first order, singular points of functions satisfying partial differential equations of the elliptic type, exposition of the work of Jacques Strum on algebraic and differential equations, boundary problems, and George Green’s functions for linear differential and difference equations, and the theorems of oscillation of Strum and Klein.

He was a member of the National Academy of Sciences and the American philosophical Society, and was a fellow of the American Academy of Arts and Sciences.
