Isaac Babbitt (July 26, 1799 in Taunton, Massachusetts – May 26, 1862 in Somerville, Massachusetts) was an American inventor; in 1839 he invented a bearing made of a low-friction tin-based metal alloy, Babbitt metal, that is used extensively in engine bearings today.
Babbitt was a goldsmith by trade, who experimented with metal alloys. In 1824 he made the first Britannia metal manufactured in the United States, from which he sold table wares as Babbitt, Crossman & Company. As this proved financially unsuccessful, he withdrew, and in 1834 moved to Boston. There he engaged as superintendent for the South Boston Iron Company, better known as Alger's foundries, where he produced the first brass cannon in the United States. Also while there, in 1839, he invented the widely-used anti-friction metal now known as Babbitt metal. For this invention he received in 1841 a gold medal from the Massachusetts Charitable Mechanic Association, and afterward the United States Congress granted him $20,000. He subsequently patented this material in England (1844) and in Russia (1847). For some time he devoted his attention to the production of the metal, and he was also engaged in the manufacture of soap.
