His full name was Oscar-Arthur Honegger, but his first name was never used. He studied harmony and violin in Paris until his parents moved to Zürich, Switzerland, when he studied at the Conservatory there. He then went back to Paris to study with Charles-Marie Widor and Vincent d'Indy. He wrote a ballet "Le dit des jeux du monde" in 1918. In 1926 he married Andrée Vaurabourg, a pianist and fellow student at the Paris Conservatoire. They often went on tour together, and his wife played the piano parts to his compositions. The couple had one daughter, Pascale, born in 1932. Honegger also had a son, Jean-Claude (1926-2003) whose mother was the singer Claire Croiza.
