Hermann Traugott Rüdisühli (10 June 1864, Lenzburg – 27 January 1944, Munich) was a Swiss painter, a member of the Rüdisühli family of artists. He created more than 1,000 paintings, primarily landscapes, portraits and allegories.
Like his siblings, Rüdisühli began his artistic training under his father, Jacob Rüdisühli. He later studied at the Kunstgewerbeschule Basel (now the Schule für Gestaltung) and from 1883 to 1887 at the Kunstakademie Karlsruhe (now the Academy of Fine Arts) in Karlsruhe, under Ferdinand Keller and Karl Brünner. From 1888 to 1898 he himself directed art schools in Stuttgart and Basel. He then moved to Munich, where he initially was successful, especially among well-born art patrons.
Like his father and brothers, Rüdisühli was greatly influenced by Arnold Böcklin.
In his later years he was impoverished. He committed suicide after his flat and studio were destroyed in an air raid during the Second World War.
