STONE, Collins, clergyman and educator, born in Guilford, Connecticut, 7 Sept, ., 1812; died in Hartford, Connecticut, 23 December, 1870. He was graduated at Yale in 1832, and in the following year became a teacher in the American deaf-mute asylum at Hartford. In 1852 he was called as principal to the Ohio state asylum for the deaf and dumb at Columbus, but he returned in 1863 to take charge of the asylum at Hartford, where he remained until his death. He studied theology, and was ordained to the ministry in 1853 while in Ohio. For nearly forty years Mr. Stone was prominent in his department of education, and merits the credit of laying the foundations of the future prosperity of the Ohio institution, and of carrying the Hartford asylum through difficulties. He published annual reports of the Ohio institution (1852-'63) and of that at Hartford (1863-'70). His other educational writings, including an address on the "History of Deaf-Mute Instruction" before the Ohio institution (1869), were published in the "American Annals of the Deaf and Dumb." A railroad accident was the cause of his death.
