Isaac Caldwell (1795 – January 12, 1836)[1] was a justice of the Supreme Court of Mississippi from 1825 to 1826.[2]
Born in Clinton, Mississippi, Caldwell became well-known as an attorney.[3] In 1829, Caldwell fought a duel with state legislator John R. Peyton over the latter's vote preventing Caldwell's hometown from being named capital of Mississippi; neither participant was injured.[3] Caldwell was the law partner of Senator George Poindexter, and following Poindexter's defeat in his 1836 bid for reelection, Caldwell ended up engaging in a duel with one of Poindexter's political opponents, Colonel Samuel Gwin.[4] The parties fought with pistols,[3] [5] and "[b]oth parties fell. Caldwell expired in two hours. Gwin was shot through the lungs and survived about a year".[4]
