Cricket
Crankshaw made headlines in 1903 when, playing for Eton, he scored a century against Harrow at Lord's. Eton won the match by 8 wickets. Crankshaw later played for Gloucestershire County Cricket Club as a right-handed batsman. He made a single first-class appearance for the side, during the 1909 season, against Surrey.
In 1929, while Churchill was serving as the Chancellor of the Exchequer, he selected Crankshaw to become Secretary of the Government Hospitality Fund. The appointment required Crankshaw to take on the role of lead host and the responsibility of promoting international goodwill on behalf of the government. His role also included oversight of Government Wine Cellar located at Lancaster House. Events under Crankshaw's charge included dinners, receptions, informal lunches, and visits to places of interest for visiting dignitaries, but also arrangements for the 1937 Coronation of George VI. He served in this capacity until his retirement in 1949.
