The Antietam Institute will wrap up their Summer Lecture Series with esteemed local historian John Schildt presenting “A Farmer, a Physician, and a General: Henry Rohrbach, Nathan Mayer, and Isaac P. Rodman.” Although not on the battlefield proper, the Henry Rohrbach farm sat just east of the Lower Bridge and would serve as a staging area for the Federal forces, a headquarters, and a hospital on September 17, 1862. A farmer, Henry Rohrbach; a surgeon, Dr. Nathan Mayer; and a soldier, General Isaac P. Rodman, would share the trauma of war at the house and barn of the Rohrbach farmstead.
