Poll seriously Andrew Jackson:
Jackson fought 13 duels, many nominally over his wife's honor. Charles Dickinson, the only man Jackson ever killed in a duel, had been goaded into angering Jackson by Jackson's political opponents. In the duel, fought over a horse-racing debt and an insult to his wife on May 30, 1806, Dickinson shot Jackson in the ribs before Jackson returned the fatal shot; Jackson allowed Dickinson to shoot first, knowing him to be an excellent shot, and as his opponent reloaded, Jackson shot, even as the bullet lodged itself in his chest. The bullet that struck Jackson was so close to his heart that it could never be safely removed. Jackson had been wounded so frequently in duels that it was said he "rattled like a bag of marbles."[53] At times he coughed up blood, and he experienced considerable pain from his wounds for the rest of his life.
On January 30, 1835, what is believed to be the first attempt to kill a sitting President of the United States occurred just outside the United States Capitol. When Jackson was leaving the Capitol out of the East Portico after the funeral of South Carolina Representative Warren R. Davis, Richard Lawrence, an unemployed and deranged housepainter from England, either burst from a crowd or stepped out from hiding behind a column and aimed a pistol at Jackson, which misfired. Lawrence then pulled out a second pistol, which also misfired. It has been postulated that moisture from the humid weather contributed to the double misfiring.[50] Lawrence was then restrained, with legend saying that Jackson attacked Lawrence with his cane, prompting his aides to restrain him. Others present, including David Crockett, restrained and disarmed Lawrence.
Theodore Roosevelt
While Roosevelt was campaigning in Milwaukee, Wisconsin, on October 14, 1912, a saloonkeeper named John Schrank shot him, but the bullet lodged in his chest only after penetrating both his steel eyeglass case and passing through a thick (50 pages) single-folded copy of the speech he was carrying in his jacket. Roosevelt, as an experienced hunter and anatomist, correctly concluded that since he wasn't coughing blood, the bullet had not completely penetrated the chest wall to his lung, and so declined suggestions he go to the hospital immediately. Instead, he delivered his scheduled speech with blood seeping into his shirt.[66] He spoke for 90 minutes. His opening comments to the gathered crowd were, "Ladies and gentlemen, I don't know whether you fully understand that I have just been shot; but it takes more than that to kill a Bull Moose." Afterwards, probes and x-ray showed that the bullet had traversed three inches (76 mm) of tissue and lodged in Roosevelt's chest muscle but did not penetrate the pleura, and it would be more dangerous to attempt to remove the bullet than to leave it in place. Roosevelt carried it with him for the rest of his life.
