John Wilkes Booth was an American stage actor who assassinated United States President Abraham Lincoln at Ford's Theatre in Washington, D.C., on April 14, 1865. A member of the prominent 19th-century Booth theatrical family from Maryland, he was a noted actor who was also a Confederate sympathizer; denouncing President Lincoln, he lamented the then-recent abolition of slavery in the United States.
