He was born in Boston to William Cooper and Judith Sewall, attended the Boston Latin School, and was graduated from Harvard College in 1743. He was ordained as a minister on May 21, 1746, and served as pastor of the Brattle Street Church, 1747-1783. Members of his parish at the Brattle St. Church included some of the most influential people of the American Revolution: John Hancock, Samuel Adams, Joseph Warren, John Adams, and others.

In 1780, he co-founded the American Academy of Arts and Sciences. He served as "chaplain to the General Court" 1758-1770 and 1777-1783. Around 1783 Harvard College offered Cooper the position of college president, but Cooper declined.[2] In September 1746 he married Judith Bulfinch; they had two daughters.[3] A portrait of Cooper by John Singleton Copley now resides in the collection of the Massachusetts Historical Society.[4]
