Octave John "Johnny" Claes (11 August 1916 – 3 February 1956) was an English-born racing driver who competed for Belgium. Before his fame as a racing driver, Claes was also a jazz trumpeter and successful bandleader in Britain.

Early life and jazz career

Claes was born in London to a Scottish mother and Belgian father. He was educated in England at Lord Williams's School. In England, he began playing trumpet in a jazz band that included Max Jones on reeds, and another with Billy Mason on piano. In the 1930s he moved to the Netherlands, where he worked with Valaida Snow and Coleman Hawkins. He also worked with Jack Kluger's band in Belgium. Returning to England, he led his own group, the Claepigeons, making a recording in 1942. In the late 1940s he abandoned his jazz career and settled in Belgium as a professional racing driver.

Racing career

Claes was one of several gentlemen drivers who took part in Grand Prix racing of post-World War II. His first contact with racing was at the 1947 French Grand Prix, where he served as interpreter for British drivers.
