Silas Hoadley of Plymouth, Connecticut.
Silas Hoadley was born in Bethany, Connecticut, on January 31, 1786. He was the son of Ammi Hoadley and Amy (Thompson) Hoadley. He first apprenticed as a joiner to his uncle Calvin Hoadley. Along with Seth Thomas, he was hired in about 1808 by Eli Terry at the age of 21 to set up and work at Terry's Ireland factory. Shortly after Terry's Porter Contract was satisfied, he and Seth Thomas bought the factory from Terry. Thomas & Hoadley continued to make tall clock movements until 1813, when he purchased Thomas's business shares. He transitioned to shelf clocks, manufacturing movements of his own design. The "Upside down" style is one of the more unique examples. In the late 1830s, he transitioned to manufacturing brass movements. He retired in 1849 as a wealthy man. Silas Hoadly died on December 28, 1870, in Plymouth, Conn.
