I read that one of our presidents shot and killed a person during a duel. Who did it?

President Andrew Jackson, Duel with Charles Dickinson 1806 before he was President.

Andrew Jackson challenged Charles Dickinson, a lawyer, to a duel for having maligned the character of Mrs. Jackson and for a misunderstanding following cancellation of an important horse race. The two squared off with pistols at the customary eight paces in a popular forest clearing in Harrison's Mill, Kentucky in 1806. Dickinson got off the first shot...a direct hit into Jackson's breast that raised dust from his coat as the bullet entered. Andrew Jackson remained so stiff that Dickinson stumbled back in sheer disbelief. At the angry shouts of Jackson's second.... demanding to return to his mark, Dickinson complied and returned to his position. Although it was commonplace for a man in Jackson's position to spare the life of his opponent by firing into the air, Jackson chose otherwise. Jackson fired his pistol. The ball penetrated Dickinson's abdomen and exited the other side... killing him instantly. The future president simply walked off the field... feet sloshing in blood that drained from his chest. Dickinson's bullet had lodged too close to Jackson's heart to be removed safely. Jackson would carry it to his grave.(

You might be thinking of the duel between Alexander Hamilton and Aaron Burr.

Aaron Burr won the duel, killing Hamilton. Neither was ever president but they were both influential founding fathers, especially Hamilton, who can today be seen on the ten dollar bill.

Below is a link giving the account of the events leading up to the duel and the duel itself.

You don't have all the facts right, but there was a duel.
