Irad "Terry" B. Hardy, III (c. 1943 - June 5, 2016) was an American wargame designer and amateur historian who was the head of research and development staff for SPI (Simulations Publications, Inc.). He helped design about 20 games for SPI between 1975 and 1978.
He should not be confused with his father Irad B. Hardy, Jr. (October 12, 1913 in Gloucester, Massachusetts - January 28, 1993 Waltham, Massachusetts) who was the former chief of surgery at Waltham-Weston Hospital and Medical Center, graduating from Harvard College and Harvard Medical School where he was an All-American football player at the tackle position. During World War II, Irad B. Hardy, Jr. served as a Navy Captain combat surgeon assigned to the 4th Marine Division artillery with the 4th Marine Division at Tarawa, Saipan, and Iwo Jima where he was awarded the Navy and Marine Corps Medal for saving lives. On February 4, 2008, his grandson U.S. Navy Seal Chief Petty Officer Nathan H. Hardy, a nephew of Irad B. Hardy, III, was killed conducting combat operations in support of Operation Iraqi Freedom.
