Biography
Caldwell Hart Colt was born in Hartford, Connecticut, the son of Samuel Colt, founder of Colt's Patent Fire-Arms Manufacturing Company (now known as Colt's Manufacturing Company) and Elizabeth Jarvis Colt. Caldwell Colt attended Yale University and was known later in life for being a yachtsman.
He served as vice-commodore of the New York Yacht Club in 1888 and commodore of the Larchmont Yacht Club from 1892–1893. He was the owner of the schooner yacht Dauntless and sloop Wizard. The New York pilot-boat Caldwell H. Colt was named in honor of Colt.
Following in his father's footsteps as a gunmaker, in 1879 he designed the Colt double barrel rifle. This rifle was chambered in .45-70 Government and is one of the rarest Colt firearms that was ever made.
