Johnny Claes

Octave John 'Johnny' Claes (born 11 August 1916 in London, died 3 February 1956 in Brussels) was a Belgian racing driver and jazz trumpeter who competed in Formula 1 from 1950 until 1955. Starting off as the owner-driver of the initially competitive Claes Racing Developments, he competed as a privateer (employing other drivers alongside him) until significant rule changes in 1953 drove him to drive for other teams, notably Leader and Mercedes-Benz before buying into Jacques Swaters' Ecurie Nationale Belge in early 1955. After a couple of entries that year, Claes retired from racing due to ill health. He died shortly thereafter from tuberculosis, aged 39.
