Pierre Humbert (mathematician)

Pierre Humbert ( born June 13, 1891 in Paris, † November 17, 1953 ) was a French mathematician.

Pierre Humbert was the son of the mathematician Georges Humbert ( 1859-1921 ). He studied from 1910 at the Ecole Polytechnique and from 1913 to 1914 at the University of Edinburgh Edmund Taylor Whittaker. After his military service in the First World War, where he was wounded, he studied in Paris again in 1918 and his doctorate (Su les surfaces de Poincaré ). After that, he was professor of astronomy at the Faculté de Science in Montpellier.

As a mathematician, he dealt with special features ( such as the Lame and Mathieu functions) and elliptic functions. He was strongly influenced by Whittaker and also worked ( as Whittaker ) on the symbolic calculus of operational calculus of Oliver Heaviside. He was the son of the astronomer Marie Henri Andoyer, with whom he published about astronomy history of the 17th century.
