Theodore Dwight Weld, American author and activist (d. 1895)
Theodore Dwight Weld (November 23, 1803 – February 3, 1895) was one of the architects of the American abolitionist movement during its formative years from 1830 to 1844, playing a role as writer, editor, speaker, and organizer. He is best known for his co-authorship of the authoritative compendium American Slavery As It Is: Testimony of a Thousand Witnesses, published in 1839. Harriet Beecher Stowe partly based Uncle Tom’s Cabin on Weld's text; the latter is regarded as second only to the former in its influence on the antislavery movement. Weld remained dedicated to the abolitionist movement until slavery was ended by the Thirteenth Amendment to the United States Constitution in 1865.According to Lyman Beecher, the father of Harriet Beecher Stowe, Weld was "as eloquent as an angel, and as powerful as thunder.": 323  His words were "logic on fire".Weld "is totally unknown to most Americans".: v 

His obscurity was of his own choosing. Weld would never accept an office of authority or honor in any antislavery organization. He refused to speak at antislavery conventions or anniversaries, or even to attend them if he could avoid it. He shunned the cities, and chose to labor in the country districts, where newspapers were few, and his activities were seldom reported except by abolition journals. His writings were published anonymously, and he would seldom allow the content of his speeches or his letters from the field to appear in print at all.: vi
