BRATTLE, Thomas, merchant, born in Boston, Massachusetts, 5 September, 1657; died there, 18 May, 1713. He was graduated at Harvard in 1676, and became treasurer of the College. He wrote "Eclipse of the Sun and Moon observed in New England," published in the "Philosophical Transactions" for 1704; "Lunar Eclipse, New England, 1707"; and a private letter giving an account of the witchcraft delusion in 1692, which is preserved in the "Massachusetts Historical Collections." --His brother, William, was pastor of the church in Cambridge, having been previously a tutor in Harvard College. He published a treatise on logic entitled "Compendium logicae secundum Principia died Renati Cartesii," which was long used as a recitation-book in the College. His death, at the age of fifty-four, occurred on 15 February, 1717. --William, son of William, loyalist, born in Cambridge, Massachusetts, about 1702 ; died in Halifax, Nova Scotia, in October, 1776. He was graduated at Harvard in 1722, studied theology, and preached acceptably; then became a lawyer, and was for many years a member of the legislature and of the governor's council. He also practiced medicine extensively, and was besides a military man, becoming captain of the artillery company in 1733, and afterward major general of militia. His talents and attractive manners made him a favorite with the governor, and popular among the people. When the revolutionary war began, his attachment to General Gage impelled him to side with the British. He withdrew to Boston, and, when the troops evacuated that City, accompanied them to Halifax. A well-known street in Boston commemorates the family.
