Nathan Sandford (sometimes spelled Sanford) was born on November 5, 1777, in Bridgehampton, Long Island, NY. He was educated at Clinton Academy in East Hampton, studied at Yale College and then in the law office of Samuel Jones. Admitted to the bar in 1799, he set up practice in New York City. He represented the plaintiff in the foxhunting case of Pierson v. Post (1805).
Sandford was appointed United States commissioner in bankruptcy in 1802 and the following year he was appointed as United States Attorney for the District of New York, a position he held until 1815. Elected to the New York Assembly in 1808 and again in 1811, Sandford was chosen Speaker of the Assembly on January 29, 1811, but ill health prevented him from holding that office for more than a few weeks.
In 1815, he was elected to the United States Senate and remained in that office until his re-election bid was defeated by Martin Van Buren in 1821. That year, Sandford served as a delegate to the New York State Constitutional Convention and, in 1823, he was appointed Chancellor of New York in place of the illustrious James Kent, who had reached the constitutionally-mandated retirement age. Three years later, Sanford, now re-elected to the United States Senate, resigned the Chancellorship. At the expiration of his Senate term, he returned to his estate in Flushing, Long Island, and resumed the practice of law.
He died on October 17, 1838.
