Huntington Hartford had $90 million at 12, lost about $30 million on Paradise Island, and was found in a Brooklyn rental at 90

Huntington Hartford was heir to the A&P supermarket fortune. When his grandfather died in 1917, he began receiving about $1.5 million a year, and by 12 he had about $90 million. In 1940 he put $100,000 into the newspaper PM. He backed a Broadway Jane Eyre, a model agency, Show magazine, a graphology institute, an oil-shale venture and an automated parking system. None succeeded under his ownership. In the late 1950s he bought a two-mile strip of land off Nassau, renamed it Paradise Island and built the Ocean Club. Without a gambling licence, he sold to Resorts International for $1 million, about $30 million less than he had put in. His Gallery of Modern Art at Columbus Circle in Manhattan failed. In 1984 his fourth ex-wife and a friend were charged over an incident involving his teenage secretary. In 2001 his daughter found him living in a squalid rental in Brooklyn and moved him to a nursing home, then to the Bahamas. He died at his home in Lyford Cay on 19 May 2008, aged 97, living with his daughter.
