Adolf Portmann (27 May 1897 – 28 June 1982) was a Swiss zoologist who focused the study of life on its appearances, ranging from morphological to semiotic aspects.
Born in Basel, Switzerland, he studied zoology at the University of Basel and worked later in Geneva, Munich, Paris and Berlin, but mainly in marine biology laboratories in France (Banyuls-sur-Mer, Roscoff, Villefranche-sur-Mer) and Helgoland.
In 1931 he became professor of zoology in Basel. His main research areas covered marine biology and comparative morphology of vertebrates. His work was often interdisciplinary comprising, morphological, behavioral, sociological and philosophical aspects of life of animals and humans.
Portmann was known for his work in theoretical biology and his comparative studies on morphology and behavior. His research has influenced the field of biosemiotics.[1]
Portmann died in Binningen near Basel on 28 June 1982.
