Eli TerryDied 26 Feb 1852 at age 79 (born 13 Apr 1772).American clockmaker who was an innovator in mass production. In 1793, Eli Terry began making clocks in Plymouth, Conn. On 17 Nov 1797, he received the first U.S. clock patent In 1802, Terry introduced wooden geared clocks using the ideas of Eli Whitney's new armory practice to produce interchangeable gears that allowed mass production of very inexpensive household clocks. When the clocks didn't sell, he proved an innovator by becoming the first retailer to offer merchandise on a free-trial, no-money-down basis. Over the following years, Terry developed ways to produce wooden clock works by machine rather than by hand. He is to clocks in the United States as Henry Ford is to automobiles.
