By profession, Geoffrey Crossley was a furniture manufacturer,[2] but he had been a keen amateur racing driver since just before World War II.

[4] Crossley also campaigned the Alta GP in selected races in 1949, including the 1949 Belgian Grand Prix, where he finished seventh and last, six laps down on the winner.

The following year he took part in the first ever World Championship Formula One race: the 1950 British Grand Prix at Silverstone Circuit.

[7] In addition to his Championship entries, Crossley also took part in a number of non-Championship races in the Alta, but at the end of the 1950 season he decided to retire due to the high costs of the sport.

[2] Owing to work and family commitments Crossley abandoned the Berkshire Special's development,[10] and withdrew from racing for good.
