Tad Lincoln, Abe Lincoln&#39;s son, was a a wild child. Before Abe became president, Tad would often trash his father&#39;s law office in Illinois. He never attended formal school but went through many private tutors who couldn&#39;t handle him. He was allowed everywhere in the White House and would often interrupt his father&#39;s meetings, bring animals inside and charge people to meet his father. He had a speech impediment that often made him impossible to understand. He died at 18 from tuberculosis.
