David G. Simons was an American physician turned U.S. Air Force lieutenant colonel who, as part of Project Manhigh, set a record of high-altitude balloon flight in 1957 at 19 miles above the Earth in an aluminum capsule suspended from a helium balloon. He received the Distinguished Flying Cross for this record. Simons was shown on the cover of Life of September 2, 1957, issue. Dr. Simons went on to a distinguished career in academic medicine as an instructor at the VA Medical Center, Long Beach, California. He authored more than 200 publications on trigger points and related treatments for chronic myofascial pain. He famously co-authored the Trigger Point Manual with Dr. Janet Travell. Originally published in 1983, it was considered a breakthrough, and remains a foundational work in the field.
