John Factor (born Iakov Faktorowicz) claimed to have been born in Hull in 1892 (although his family stated that he was born in Lodz in Poland four years earlier). In 1904, he emigrated to the United States with his family, and grew up in St Louis and then New York. Initially Factor worked as a barber before becoming involved with organised crime, meeting the mobster Arnold Rothstein. Although indicted multiple times for stock and land fraud for various schemes in the United States, he was never charged. By 1923 was living in a 14-room flat.
