Born in
Hampstead, London, Hatry began his professional career as an
insurance clerk in London's
West End. Shrewd fellow-promoters remembered that "Clarence" made his first big profit in silk. He then recouped the ensuing bankruptcy in insurance, through City Equitable, a modest
reinsurance business. It was bought from German and Austrian owners in 1914 for £60,000; Hatry reorganised it in six months and sold a controlling interest for £250,000 () to
Gerard Lee Bevan and an associate called Peter Haig Thomas. Hatry found the First World War a chance to profiteer, and by 1921, he was the respected director of 15 corporations. He had already come to the attention of the American public for a different reason: transporting Eastern European immigrants to the United States and Canada. In 1924, his Commercial Corporation of London failed for $3.75 million (). In some manner, three successive bankruptcies had left him successively richer. He built a new business empire, with investments in photographic supplies, cameras, vending machines,
department stores and loan offices. In early 1929 investors flocked to the Hatry group: General Securities Ltd. (of which
Henry Paulet, 16th Marquess of Winchester, was chairman); Austin Friars Trust, Ltd., Dundee Trust, Oak Investment Corp., Associated Automatic Machines Corp., Retail Trade Corp., Photomaton Parent Corp. and Far Eastern Photomaton Corp. Photomaton Parent Corporation Limited was set up by Clarence Hatry in 1928 to operate photograph machines in hundreds of public places such as railway stations and amusement parks. By 1929, he had returned to the top table of corporate finance, and had worked out his greatest project, a merger of steel and iron concerns into the $40 million
United Steel Companies. Just as this deal was to be consummated, the Stock Exchange Committee caught him borrowing $1 million () on worthless paper. On 20 September 1929, the fraud became known, and the Hatry empire collapsed. ==Personal life==
