David Edgar Herold (June 16, 1842 – July 7, 1865) conspired with John Wilkes Booth to assassinate Abraham Lincoln. Herold was born in Maryland, the sixth of ten children of Adam and Mary Porter Herold. He grew up in a large brick house near the Washington Navy Yard, attended Gonzaga College High School, Georgetown College, and Rittenhouse Academy, and worked as a pharmacist and as a clerk for a doctor. He also was an avid hunter. Herold attended Charlotte Hall Academy, where he met John Surratt, who introduced him to Booth. For a time in 1864 Herold was employed in Brooklyn, New York, by Francis Tumblety, a quack "Indian Herb" doctor who would be arrested in St. Louis, Missouri in the manhunt following the Lincoln assassination and then released. Years later, Tumblety would be numbered among the Jack the Ripper suspects. On the night of April 14 1865, Herold guided Lewis Powell (aka Lewis Payne) to the house of Lincoln's Secretary of State, William H. Seward. Inside, Powell attempted to kill Seward, severely wounding him and other members of his household. The ensuing commotion frightened Herold and he rode off, leaving Powell to fend for himself. Another conspirator claimed that Herold was to have killed Vice President Andrew Johnson, but this attack was never carried out. *David Herold * samuelmudd.com (via Wikipedia)
