Thaddeus Mason Harris, clergyman, born in Charlestown, Massachusetts, 7 July, 1768; died in Dorchester, Massachusetts, 3 April, 1842. He was a descendant in the sixth generation of Thomas Harris, of Ottery St. Mary, Devonshire, England. His father was a Revolutionary patriot, who died during the war, leaving his family destitute. Thaddeus was sent to earn his living with a farmer in the township of Stirling, Massachusetts, and received some schooling with the farmer's children. He entered the school of Dr. Morse, a suspected Tory, who prepared him for college, and in 1787 he was graduated at Hat-yard. Through the influence of friends he was in this year invited to become private secretary to General Washington, but was prevented by an attack of small-pox. He taught at Worcester a year, studied theology, and in 1781 was appointed librarian at Harvard. He accepted a call in 1793 from the 1st Unitarian church at Dorchester, and remained its pastor till three years before his death. Harvard gave him the degree of D. D. in 1813. He published "Discourses in Favor of Freemasonry" (Boston, 1803); "Journal of a Tour of the Territory Northwest of the Alleghany Mountains" (1805); "A Natural History of the Bible" (1821); "Memorials of the First Church at Dorchester" (1830); and "Biographical Memoirs of James Oglethorpe" (1841).
