Octavius Brooks Frothingham

Born in Boston in 1822, he was the son of the prominent Unitarian minister Nathaniel Langdon Frothingham. He studied at Harvard College and Harvard Divinity School, then began his ministry in Salem before serving in Jersey City and New York.

Over time, his preaching moved in a more radical and independent direction, shaped in part by the influence of Theodore Parker. He became known not only as a clergyman but also as a lecturer, critic, and author with a strong interest in religious liberalism, philosophy, and reform.

He is especially remembered for writing about the Transcendentalists and for helping preserve the intellectual history of New England Unitarianism. His books and memoirs remain useful to readers interested in American religion, culture, and ideas in the 1800s.
