About the author

Born in Boston in 1818, John Weiss became a Unitarian clergyman, author, and public reformer. Reliable biographical sources describe him as an abolitionist and an advocate of women's rights, and note that he studied at Harvard College and Harvard Divinity School before serving congregations in Massachusetts.

Alongside his ministry, he built a literary career that ranged across religion, criticism, biography, and essays. He is especially remembered for works such as Life and Correspondence of Theodore Parker and American Religion, which reflect his interest in both moral reform and the intellectual life of his time.

Weiss died in 1879, but his career still offers a vivid picture of the outspoken liberal religious culture of 19th-century New England. For readers coming to him now, he stands out as a writer who linked faith, conscience, and social action in a direct and energetic way.
