Donald Crowhurst
Donald Charles Alfred Crowhurst (1932 – July 1969) was a British electronics engineer, businessman, and amateur sailor who disappeared while competing in the Sunday Times Golden Globe Race, a single-handed, round-the-world yacht race held in 1968–1969. Crowhurst, a developer of (chiefly marine) electronic products with a poorly performing small business "Electron Utilisation", believed that pursuing the £5,000 prize money offered by the race organisers would offer a financial lifeline for his business, and that successful completion of the race would also showcase a number of new products that he had in mind as safety devices for yachts, in addition to the personal recognition that might ensue.
