Presentation copy of the first American publication on teaching the deaf, written by the architect of the U.S. Capitol

The bulk of this treatise deals with the idea of a universal alphabet, but it includes the essay at the end (pp. 94-110) that is the first work upon the education of the deaf actually written and published in America. In it, the author suggests the modern method of teaching the deaf to speak, for which the American Philosophical Society awarded him the Magellanic gold medal.

Thornton (1759-1828), the son of a West Indian planter, was educated in Great Britain. He emigrated to the United States in 1786 and became a U.S. citizen two years later. A polymath, his interests and activities were astonishingly varied. Trained as a doctor, he soon turned his attention to architecture, designing the first building for the Library Company of Philadelphia (1789) and winning the competition to design the U.S. Capitol in Washington. Thornton was associated with John Fitch in the development of a steam-driven paddle boat and was appointed to head the fledgling U.S. Patent Office in 1802, and was an early advocate of abolition and African colonization.
