US Senator. The son of General Frederick Frelinghuysen, he graduated from the College of New Jersey (now known as Princeton University) in 1804, and was admitted to the New Jersey Bar in 1808. In 1817 he was appointed as Attorney General of New Jersey, serving in that office from 1817 to 1829. He was then elected as an Anti-Jacksonian Senator from New Jersey to the United States Senate, serving from 1829 to 1835. He set up a law practice in Newark, New Jersey, and served as the city's Mayor from 1837 to 1838. In 1844 he was selected by Kentucky Senator Henry Clay to his Vice Presidential running mate in Clay's bid for the Presidency of the United States; a run that saw them defeated by the James Knox Polk-George M. Dallas ticket. His later years saw him serve as President of Rutgers University in New Brunswick, New Jersey from 1850 until his death in 1862. A strong defender of Native American Rights, as a Senator he made a six hour speech over the course of three days passionately opposing President Andrew Jackson's Indian Removal Act of 1830. His nephew, Frederick Theodore Frelinghuysen, later served as a Senator from New Jersey and as United States Secretary of State in President Chester A. Arthur's Administration.
