Career
Hickman, a politician and businessman, served as Prime Minister of Newfoundland for 33 days in 1924 as leader of a caretaker administration after the successive collapses of the Liberal Reform Party governments of Prime Ministers Sir Richard Squires and William Warren. The governor asked Hickman to form an administration to govern the province when the government of William Warren was defeated in a Motion of Number Confidence. His new party was defeated in the 9 June 1924 election by former supporters of Warren who joined with the conservative opposition to form the Liberal-Conservative Progressive Party.
