Bill Brack

Bill Brack, a Canadian driver born in 1935, made three World Championship starts spread across three separate seasons. He debuted in 1968 with a Lotus-Ford at the age of thirty-two, then appeared with BRM in 1969.

After a two-year absence from the championship, he returned for one final start with BRM in 1972. None of his three outings produced points, and each came as a single-race entry rather than part of a full campaign.

His pattern of appearances — one start per season, four years apart at the extremes — is characteristic of drivers who entered their home Grand Prix in the late 1960s and early 1970s while racing primarily elsewhere.
