David Edgar Herold (June 16, 1842 July 7, 1865) accomplice of John Wilkes Booth in the assassination of Abraham Lincoln. After guiding fellow conspirator Lewis Powell to the home of Secretary of State William H. Seward, whom Powell attempted to kill, Herold fled and met with Booth outside of Washington, D.C. They then proceeded to Surrattsville, Maryland where they picked up weapons that Mary Surratt had left earlier for them at her property. Since Booth had broken his leg earlier in the escape, Herold accompanied him to the home of Dr. Samuel Mudd. Herold and Booth continued their escape through Maryland and into Virginia, and Herold remained with Booth until the authorities found them. He was tried and sentenced to death by hanging.
