André Maublanc

André Pierre Jules Maublanc (24 July 1880 in Nantes – 30 April 1958 in Paris) was a French mycologist and plant pathologist.

Beginning in 1902 he worked as a préparateur at the Station de Pathologie végétale in Paris. In 1912 he traveled to Brazil, where he was responsible for organizing the plant pathology laboratory at the National Museum in Rio de Janeiro. In 1921 he was named head (chef de travaux) of botany and plant pathology at the Institut nationale agronomique.

From 1909 he served as general secretary of the Société mycologique de France, and in 1945 was named president of the Société botanique de France. The mycological genera Maublancia (G.Arnaud, 1918) and Maublancomyces (Herter, 1950) commemorate his name.
