Letterman Army Medical Center, located in the Presidio of San Francisco, California, was established in 1898 and named after Major Jonathan Letterman, the "Father of Battlefield Medicine." The center played a crucial role during both World Wars, the Korean War, and the Vietnam War, serving as a major treatment and evacuation hospital for wounded service members returning from the Pacific Theater and other regions. Throughout its history, Letterman became renowned for its advancements in military medical care, rehabilitation, and research. The hospital was decommissioned in 1994, but its legacy endures in military medicine and the ongoing use of its site for medical and technological innovation.
