1811–1893
A 19th-century lawyer and reform-minded writer, he moved easily between law, politics, abolitionism, and spiritual debate. His books ranged from constitutional arguments against slavery to practical legal manuals and works on Spiritualism.
Born in 1811 and dying in 1893, Joel Tiffany was an American attorney, author, and public thinker whose career reached across several fields. Contemporary library records link him to major legal works including A Treatise on the Unconstitutionality of American Slavery (1849), The New York Practice (1865, with Henry Smith), and A Treatise on Government, and Constitutional Law (1867). Those works show both sides of his writing life: he could be a practical legal compiler and also a forceful political thinker.
Tiffany is especially notable for arguing against slavery on constitutional grounds. A modern teaching edition of his 1849 antislavery treatise describes him as one of the writers who developed an antislavery interpretation of the United States Constitution, and other records connect him with service as a reporter for the New York Supreme Court. Family and memorial sources also describe him as a teacher, abolitionist, inventor, and active participant in Republican politics.
He also wrote extensively on Spiritualism, with books and lectures such as Lectures on Spiritualism, Spiritualism Explained, and later works on clairvoyance and mediumship. That mix of legal scholarship, reform writing, and religious controversy makes him an unusually wide-ranging figure of 19th-century American intellectual life.
