George Atzerodt
George Andrew Atzerodt was a conspirator, with John Wilkes Booth, in the assassination of U.S. President Abraham Lincoln. Assigned to assassinate U.S. Vice President Andrew Johnson, he lost his nerve and did not make an attempt. He was executed along with three other conspirators by hanging.
Atzerodt was born in Drna, today part of Anrode, Germany. He immigrated to the United States in 1843 at the age of eight. As an adult, he opened his own carriage repair business in Port Tobacco, Maryland.
