Donald Charles Alfred Crowhurst (1932–1969) was a British businessman and amateur sailor who died while competing in the Sunday Times Golden Globe Race, a single-handed, round-the-world yacht race. Crowhurst had entered the race in hopes of winning a cash prize from The Sunday Times to aid his failing business. Instead, he encountered difficulty early in the voyage, and secretly abandoned the race while reporting false positions, in an attempt to appear to complete a circumnavigation without actually circling the world. Evidence found after his disappearance indicates that this attempt ended in insanity and suicide.
Crowhurst was born in 1932 in Ghaziabad, British India. His mother was a school teacher and his father worked on the Indian railways. During her pregnancy, his mother had longed for a daughter, and Crowhurst was raised as a girl until the age of seven. After India gained its independence, his family moved back to England. The family's retirement savings were invested in an Indian sporting goods factory, which later burned down during rioting after the Partition of India.
Crowhurst's father died in 1948. Due to family financial problems, he was forced to leave school early and started a five-year apprenticeship at the Royal Aircraft Establishment at Farnborough Airfield. In 1953 he received a Royal Air Force commission as a pilot, but was asked to leave the Royal Air Force in 1954 for reasons that remain unclear, and was subsequently commissioned in to the Royal Electrical and Mechanical Engineers in 1956. After leaving the Army in the same year owing to a disciplinary incident, Crowhurst eventually moved to Bridgwater, where he started a business called Electron Utilisation. He was active in his local community as a member of the Liberal Party and was elected to Bridgwater Borough Council.
