Early life

Seymour was born in Litchfield, Connecticut on May 31, 1778, the son of Mary (Molly) Marsh Seymour and Major Moses Seymour, a veteran of the American Revolution, the longtime Litchfield town clerk, and a member of the Connecticut House of Representatives. Horatio Seymour attended the local schools, and was tutored by his brother in law, the Reverend Truman Marsh. Seymour graduated from Yale College in 1797 and received his master of arts degree from Yale in 1799. He taught school in Cheshire, Connecticut, and studied at the Litchfield Law School. Seymour then moved to Middlebury, Vermont, completed his legal training in the office of Daniel Chipman, and was admitted to the bar in 1800.

Start of career

Seymour established a successful law practice in Middlebury. He also trained several prospective attorneys in his office, including Edward John Phelps, John C. Churchill, and John Wolcott Stewart. He was active in the Episcopal Church, and the management of the Addison County Grammar School and Middlebury College.

From 1800 to 1809 Seymour was Middlebury's postmaster. He was a member of the State executive council from 1809 to 1814, and state’s attorney for Addison County from 1810 to 1813 and 1815 to 1819.

In 1820 Seymour was a successful Democratic-Republican candidate for the United States Senate. He was reelected as a National Republican in 1826, and served from March 4, 1821 to March 3, 1833. He did not run for re-election in 1833. During his Senate career, Seymour served as chairman of the Committee to Audit and Control the Contingent Expenses (18th and 19th Congresses), and the Committee on Agriculture (22nd Congress).

Later career

Seymour continued his Middlebury law practice after leaving the Senate. By now a Whig, he ran unsuccessfully for Governor of Vermont several times in the 1830s in an ultimately successful effort to have his new party supplant the Anti-Masonic Party as the main alternative to the Democratic Party. From 1847 to 1856 he served as Addison County's probate court judge.

Death and burial

Seymour died in Middlebury, Vermont on November 21, 1857. He was buried in Middlebury's West Cemetery.


In 1800 Seymour married Lucy Case of Addison. They were the parents of four sons and two daughters. Lucy Case Seymour died in 1838.

Seymour's son Ozias (1801-1861) was an attorney in Middlebury, and served as Addison County State's Attorney.
