Jim Hurtubise

Jim Hurtubise, an American driver born in 1932, made a single World Championship start, driving a Christensen in 1960 at the Indianapolis 500, which counted toward the Formula 1 World Championship from 1950 to 1960.

The appearance came in the final year of the race's inclusion on the championship calendar and brought no points. That one start constitutes his entire Formula 1 record.
