Chauncey Jerome of New Haven, Connecticut.
Chauncey Jerome was born in 1793 in Canaan, Connecticut, the son of a blacksmith and a nail-maker. He has a storied history in the Connecticut clock industry, becoming one of our nation's giant employers and producers during his lifetime. His autobiography has been reprinted and is available at the American Clock and Watch Museum in Bristol, CT. It is a worthy read.
Chauncey began his clockmaking career as a joiner. First, making wooden dials for tall clocks, and then in 1816, he went to work for Eli Terry. Jerome made the cases for Terry's Pillar & Scroll shelf clocks. Soon, he decided to work for himself, making cases and trading them with Terry for his movements. By 1822, Jerome moved his business to Bristol. He was an innovator in clock case construction and design. In 1842, he again moved his shop, this time to New Haven.
In 1850, Jerome formed the Jerome Manufacturing Company. In 1853, he formed the New Haven Clock Co.
Throughout his lifetime, he weathered numerous business disasters and windfalls. He was a well-respected citizen and served in the state legislature and as mayor of New Haven. He died penniless in 1868.
