Walt Brown

Walt Brown, an American driver born in 1911, made two World Championship starts in 1950 and 1951, both driving Kurtis Kraft machinery at the Indianapolis 500, which counted toward the Formula 1 World Championship from 1950 to 1960.

Neither appearance produced points or a classified championship position. His record therefore reads as two starts across two seasons in the earliest years of the World Championship, made when he was approaching his fortieth birthday.
