William Jay (June 16, 1789 – October 14, 1858) was an American abolitionist and jurist, son of Governor of New York and first U.S. Supreme Court Chief Justice John Jay. Early life Jay was born in New York City on 16 June 1789, in between his father's terms as United States Secretary of Foreign Affairs in the administration of George Washington. He was the son of John Jay (1745–1829) and Sarah Van Burgh (née Livingston) Jay (1756–1802). Among his older siblings was Peter Augustus (who served as Recorder of New York City under Richard Riker), Susan, Maria, and Ann Jay. His maternal grandparents were Susannah (née French) Livingston and William Livingston, an attorney who was a signer of the United States Constitution and later served as the first post-colonial Governor of New Jersey during the American Revolutionary War. His paternal grandparents were Peter Jay, a wealthy trader in furs, wheat, timber, and other commodities, and Mary (née Van Cortlandt) Jay (daughter of New York mayor Jacobus Van Cortlandt). He graduated from Yale College in 1808. Career After his graduation, he took up the management of his father's large estate in Westchester County, New York, and also studied law at Albany. Poor eyesight soon compelled him to give up the legal profession. He early became interested in various philanthropic enterprises and reforms and identified himself especially with the temperance, antislavery, and antiwar movements. He was one of the founders (in 1816) of the American Bible Society, which he defended against the vigorous attacks of the High Church party, led by Bishop John H. Hobart. He was Judge of Common Pleas in New York from 1818 to 1820, and was first judge of Westchester County from 1820 to 1842, when he was removed on account of his anti-slavery views. An enthusiastic member of the American Anti-Slavery Society, whose constitution he drafted, Jay stood with James Birney at the head of the conservative abolitionists, and by his calm, logical, and judicial writings exerted for many years a powerful influence. From 1835 to 1837 he was the society's corresponding foreign secretary. In 1840, however, when the society began to advocate measures which he deemed too radical, he withdrew his membership, but with his pen he continued his labor on behalf of the slave, urging emancipation in the District of Columbia and the exclusion of slavery from the territories, though deprecating any attempt to interfere
