Burr studied theology for a while and then law. After the Revolutionary War, in which he served with distinction as a field officer, he took up the practice of law in New York City and entered politics, serving as a member of the New York state assembly, attorney general of New York, and United States senator. In the presidential election of 1800, he received the same number of electoral votes as Thomas Jefferson, but the tie was broken in the House of Representatives in Jefferson's favor, and Burr became vice-president.
Four years later, on July 11, 1804, in the historic duel at Weehawken, New Jersey, Burr mortally wounded his professional rival and political enemy, Alexander Hamilton. Thereafter came his errant political adventures in the West, his trial for treason, and his acquittal.
Burr's chief counsel at the trial was Luther Martin 1766, a fellow member and one of the founders of the Cliosophic Society. A few years before his death, the society invited Burr to preside at its commencement meeting, and its members took part in the procession at Burr's funeral in Princeton in 1836. President Carnahan preached the funeral sermon in Nassau Hall (in which he decried the evils of dueling). Escorted to the Princeton Cemetery by members of the faculty, students, alumni, a military band, and the Mercer Guards, Burr was buried with full military honors at the foot of his father's and grandfather's graves in the President's Lot.
