Daniel Edgar Sickles
(1819-1914)
In his pre- and post-Civil War careers, as well as during the conflict, Daniel E. Sickles proved to be one of the most controversial of Union corps commanders. Prewar, the New York City native had already become the first man acquitted of a murder charge on the grounds of temporary insanity. Sickles, a congressman, shot down Philip Barton Key-the son of the composer of the "Star Spangled Banner"-in LaFayette Park,across the street from both Sickles' home and the White House. Key had been having an affair with Sickles' wife, whom Sickles had married while serving as secretary of the U.S. legation in London. Defense attorney Edwin M. Stanton gained the innovative verdict.
