“ Returning to the United States in 1816, he established at Hartford, Connecticut, with the aid of Laurent Clerc (1785–1869) , a deaf mute assistant of the abbé Sicard, a school for deaf mutes, in support of which Congress, largely through the influence of Henry Clay, made a land grant, and which Gallaudet presided over with great success until ill-health compelled him to retire in 1830. It was the first institution of the sort in the United States, and served as a model for institutions which were subsequently established. He died at Hartford, Connecticut, on the 5th of September 1851. ”
