Jean Feldmann (1905–1978) was a French biologist, specialising in marine algae.
[2] He initially studied pharmacy, gaining his first degree in 1929, before turning his attentions to marine algae.
[1] The couple moved to Paris when Jean took up a position at the institution that became the Université Pierre et Marie Curie, where they remained until his retirement in 1976.
[1][2] Feldmann published around 220 scientific works, mostly on marine algae, but also covering various fungi, mosses, freshwater algae and flowering plants.
[1] Feldmann strongly believed in international scientific co-operation[3] and, as well as co-founding the Société Phycologique de France in 1955, strongly advocated the foundation of an International Phycological Society,[1] of which he served as the first president from its foundation in 1961 until his retirement.
