Life story
Worcester Warner was born on a Cummington, Massachusetts farm in 1846. He met Ambrose Swasey as an apprentice at Exeter Machine Works, and both worked at Pratt & Whitney in Hartford from 1870.
They founded Warner & Swasey in 1880, starting in Chicago and then moving to Cleveland. The firm became known for telescopes, though its profits came from machine tools and military instruments.
Warner was the 16th president of the American Society of Mechanical Engineers and a trustee of Case School of Applied Science. He and Swasey gave Case their private observatory, dedicated as the Warner and Swasey Observatory in 1920.
He moved to Tarrytown, New York, in 1911 and died in Germany in 1929. He is buried at Sleepy Hollow Cemetery. A medal for ASME and a lunar crater carry his name.
