Established in 1907, as a series of wooden structures on Fort Shafter Flats, it was renamed Tripler Army Medical Center in 1920 after Brig. Gen. Charles Stuart Tripler, the legendary American Civil War medic who made significant contributions to military medicine. The current facility was commissioned in 1942 by Lt. Gen. Robert C. Richardson Jr., Military Governor of the Territory of Hawaii during World War II. In 1948, construction was completed on the then-tallest skyscraper in the Pacific. It boasted the latest advances in both medicine and building construction and served as place of solace for the U.S. Army Soldier to rest and recuperate both physically and mentally. A major expansion in 1985, added 433,000 square feet of space.
