August Wenzinger (1905–1996) was a prominent cellist, viol player, conductor, teacher, and music scholar from Basel, Switzerland. He was a pioneer of historically informed performance, both as a master of the viola da gamba and as a conductor of Baroque orchestral music and operas. 　　Wenzinger received his basic musical training at the Basel Conservatory, then went on to study cello with Paul Grümmer and music theory with Philipp Jarnach at the Hochschule für Musik in Cologne. He then took private cello lessons with Emanuel Feuermann in Berlin. Wenzinger served as first cellist in the Bremen City Orchestra (1929–1934) and the Basel Allgemeine Musikgesellschaft (1936–1970). 　　By 1925 Wenzinger had mastered the viola da gamba, an instrument then usually considered obsolete. He joined the Kabeler Kammermusik (Kabel Chamber Music), a circle of musicians interested in authentic Baroque performance, sponsored by paper manufacturer Hans Eberhard Hoesch in Hagen, Germany. In 1930 he and flautist Gustav Scheck also founded the Kammermusikkreis Scheck-Wenzinger (Scheck-Wenzinger Chamber Music Circle), considered the leading early music ensemble until the 1950s.
