Weld, Theodore Dwight, 1803–95, American abolitionist, b. Hampton, Conn. In 1825 his family moved to upstate New York, and he entered Hamilton College. While in college he became a disciple of the evangelist Charles G. Finney and was influenced by Charles Stuart, a retired British army officer who urged Weld to enlist in the cause of black emancipation. While studying for the ministry at Oneida Institute he traveled about lecturing on the virtues of manual labor, temperance, and moral reform. After 1830 he became one of the leaders of the antislavery movement working with Arthur Tappan and Lewis Tappan, New York philanthropists, James G. Birney, Gamaliel Bailey, Angelina Grimké, and Sarah Grimké. He married Angelina Grimké in 1838. Weld chose Lane Seminary at Cincinnati, Ohio, for the ministerial training of other Finney converts and studied there until the famous antislavery debates he organized (1834) among the students led to his dismissal. Almost the entire student body then requested dismissal, and it was from these theological students that Weld and Henry B. Stanton selected agents for the American Anti-Slavery Society. The "Seventy," as the agents were called, gave character and direction to the antislavery movement and successfully spread the abolitionist gospel throughout the North. From 1836 to 1840, Weld worked at the New York office of the antislavery society, serving as an editor of the society's paper, the Emancipator, and contributing antislavery articles to newspapers and periodicals. He also directed the national campaign for sending antislavery petitions to Congress and assisted John Quincy Adams when Congress tried Adams for reading petitions in violation of the gag rule. While in Washington he advised the Northern antislavery Whigs, many of whom (e.g., Ben Wade, Thaddeus Stevens) were converted to the cause by Weld or one of his agents. After 1844 he retired from public participation in the movement to found a school, Eaglewood, near Raritan, N.J. During the Civil War, at the urging of William Lloyd Garrison, he came out of retirement to speak for the Union cause and campaign for Republican candidates. Most famous of his writings (none was published under his own name) was American Slavery As It Is (1839), on which Harriet Beecher Stowe partly based Uncle Tom's Cabin and which is regarded as second only to that work in its influence on the antislavery movement. Many historians regard Weld as the most important figure in the abolitionist movement, surpassing even Garrison, but his passion for anonymity long made him an unknown figure in American history.
