Gontran Georges Henri Hamel (1883–1944) was a French phycologist.
In 1927 he earned his doctorate in natural sciences with a thesis on the red algae genera Acrochaetium and Rhodochorton.[1] He is known for research performed in the "Laboratoire de Cryptogamie" at the Museum d'Histoire Naturelle in Paris.[2] He reportedly died while trying to reach Paris by bicycle prior to its liberation in August 1944.[3]
In 1924 with Pierre Allorge (1891–1944), he was co-founder of the journal Revue algologique.[4] Since 1927 he was also the editor and a contributor to the exsiccata series Algues de France.[5][6]
In 1942 Frederik Børgesen named the brown algae genus Hamelella (family Chordariaceae) in his honor.[3][7] Also, the red algae species Lithothamnion hamelii is one of several species that bear his name.[8]
