Helmut Gams (1893–1976) was a central European botanist. Born in Brno, he moved to Zürich as a child. He studied at the University of Zurich, being awarded a PhD in 1918. During his career, he worked at the University of Munich and the University of Innsbruck. His research saw him pursue fieldwork around Europe and Asia. He was a geobotanist who specialized in the associations of different species of mosses and lichens with each other and the environment.[1][2] Gams coined the terms 'biocoenology' and 'phytocoenology' in his 1918 PhD thesis.[3][4]
Two species named after Gams are Phacus gamsii and Rumex gamsii.[5]
