Johnson, Andrew

17th President of the United States, Democrat.  In Office: April 15, 1865 – March 4, 1869.  Born: December 29, 1808. Died: July 31, 1875.  Served as 16th Vice President of the United States under Abraham Lincoln.  Johnson became President after the assassination of President Lincoln and served during the Reconstruction Period.  Johnson was impeached in March of 1868, but was acquitted by the Senate in May of 1868.  Johnson was the third U.S. President to have his veto overridden by Congress, an action that became common during his presidency (15, which remains the most for any President), due to disagreements regarding reconstruction strategies.
