A Swiss ecologist who devised the most widely used of European phytosociological methods for the description of vegetation communities, and who was generally acknowledged as the foremost authority on such schemes. He developed the framework for his system in this doctoral study of the vegetation of the central Cévennes (1915), and the fully developed method was published in his authoritative textbook Pflanzensoziologie (Springer, Berlin, 1928) which he revised and updated most recently for a third, enlarged edition published in 1964. He worked at, and for many years was director of, the Station Internationale de Géobotanique, Méditerranéenne et Alpine (SIGMA) at Montpellier, France.
