Parker (Theodore) is born in Lexington.

The grandson of Capt. John Parker Lexington Green fame, Theodore Parker graduates from Harvard Divinity School, marries Lydia Cabot and is named minister of the Second Church in West Roxbury in 1837, and lives on today’s St. Theresa Avenue. He subsequently writes to his brother, “I preach abundant heresies, and they all go down, for the listeners don’t know how heretical they are. I preach . . . Transcendentalism, the grand heresy itself, none calling me to account therefore.” He becomes minister at the Twenty-Eighth Congregational Society in 1846,* becomes a well-known and well-traveled speaker, abolitionist, and writer. Parker dies in Florence, Italy May 10, 1860, and is buried there in the Protestant Cemetery.
