Philip Barton Key II

Philip Barton Key II (April 5, 1818 – February 27, 1859) was an American lawyer who served as U.S. Attorney for the District of Columbia. He is most famous for his public affair with Teresa Bagioli Sickles, and his eventual murder at the hands of her husband, Congressman Daniel Sickles of New York. Sickles defended himself by adopting a defense of temporary insanity, the first time the defense had been used in the United States. Biography Born in Georgetown, D.C., Key was the son of Francis Scott Key and the great-nephew of Philip Barton Key. He was also a nephew of Chief Justice Roger B. Taney. He married Ellen Swan, the daughter of a Baltimore attorney, on November 18, 1845. Allegedly the most handsome man in Washington and by 1859 a widower with four children, Key was known to be flirtatious with many women. Key was appointed to his father's former position, United States Attorney for the District of Columbia, by President Pierce in September 1853, during a recess of the Senate; the Senate later confirmed his nomination in March 1854. Four years later, he was nominated, and confirmed again, for another four-year term; thus, he would serve until his death.
