George Andrew Atzerodt (June 12, 1835 – July 7, 1865)[1][2] was a German American repairman, Confederate sympathizer, and conspirator in the assassination of U.S. President Abraham Lincoln.

[7] Atzerodt was willing to join in Booth's earlier conspiracy to kidnap President Abraham Lincoln, as he later admitted in his trial.

According to the prosecution, Booth assigned Atzerodt to assassinate Vice President Andrew Johnson on April 14, 1865.

At 10:15 P.M. that night, the same moment John Wilkes Booth shot Abraham Lincoln at Ford's Theater, Lewis Powell attacked the already injured Secretary of State William Seward, but Atzerodt could not muster the courage to kill Andrew Johnson.

Butler said that Atzerodt admitted going to the meeting in March to help plan the kidnapping of Lincoln while he attended a play at a hospital.

[9] Atzerodt and three other convicted conspirators (Mary Surratt, Lewis Powell, and David Herold) were hanged in Washington, D.C., on July 7, 1865.

In the episode, he makes an attempt to assassinate Johnson but is stopped by Rufus and other soldiers and arrested by the authorities.
