Georges Valiron

Georges Valiron was a French mathematician, born in Lyon in 1884 and active until his death in Paris in 1955, known above all for work in analysis: the theory of entire and meromorphic functions, holomorphic functions and Tauberian theorems. He studied at the École Normale Supérieure in Paris and taught secondary school at Besançon, where his pupils included André Bloch, before doing doctoral research advised by Émile Borel and defending his thesis in Paris on 20 June 1914. After artillery service in the First World War he was a professor at Valence and then taught at Strasbourg from 1921, becoming professor there in 1922. His 1922 lectures at Aberystwyth became Lectures on the general theory of integral functions, still in print in the twenty-first century. From 1931 he held a chair at the Faculty of Science in Paris and taught at the École Polytechnique; his two-volume Cours d'Analyse mathématique appeared in 1942 and 1945.
