(1813-1887) Preacher, reformer, and abolitionist, he was the son of famed evangelist Lyman Beecher and brother of author Harriet Beecher Stowe. In the 1850s, he helped raise money to support the New England Emigrant Aid Company in its efforts to keep slavery out of Kansas Territory. After the Civil War, he emerged as perhaps the best-known Protestant minister, in part because of his ability to adapt Christianity to fit the times, emphasizing the compatibility of religion, science, and modernity.
