He was born in Winterthur, where he attended primary and high school, and later studied at the Zurich Conservatory and at the University. He also taught piano, counterpoint, composition, and wrote about music. He wrote "3 ländler op.28" for 4 hand piano duet.
He was a bassoonist with the Winterthur Stadtorchester from 1942 to 1971.
Among his compositions is the Sonata for Viola & Bassoon, the only classical-style chamber work written for that combination of instruments.
