Alphonse Demoulin

Alphonse-Adolphe-Auguste Demoulin (born September 20, 1869 in Brussels , † June 25, 1947 in Gent ) was a Belgian mathematician who dealt with geometry ( projective geometry , differential geometry ).

Demoulin attended the Athenaeum in Brussels and studied at the University of Ghent with a degree in 1889 and a doctorate in 1890 and then in Paris with Gaston Darboux , where he received his doctorate in 1892. From 1893 he was a repetitor, from 1898 Chargé de Cours, 1899 associate professor and from 1904 full professor in Ghent, where he lectured until 1936 when there were no more French lessons there due to the flamingo. In 1939 he retired.

He was one of the pioneers in projective differential geometry.

Demoulin received the Poncelet Prize in 1945 and the Prix Bordin of the Académie des Sciences in 1911 . He received honorary doctorates in Brussels, Montpellier and Toulouse. In 1903 he became a corresponding and in 1911 full member of the Royal Belgian Academy of Sciences and in 1927 its president.
