The streak was broken in the last dual meet of the 1930–31 season against cross-state rival, the University of Oklahoma Sooners. During the rest of the 1930s, the Cowboys lost only one other dual meet (at Southwestern Oklahoma State in the 1936–37 season) and had three ties. In 1928, the National Collegiate Athletic Association (NCAA) held its first national college wrestling championship. At that first NCAAs—hosted by Iowa State—Gallagher's wrestlers won four of the seven titles. In the thirteen years of NCAA championships with Gallagher as coach, 22 individual Cowboy wrestlers won a total of 37 NCAA titles. Olympic success From 1924 through 1936, fifteen of Ed Gallagher's wrestlers qualified for U.S. Olympic teams, along with Earl McCready competing for his native Canada at the 1928 Olympics, and George Chiga wrestling for Canada in 1936. Four Cowboy Olympic wrestlers coached by Gallagher earned medals. Bobby Pearce and Jack VanBebber both won gold medals at the 1932 Los Angeles Olympics. At the 1936 Berlin Olympics, Frank Lewis won the gold, while teammate Ross Flood earned silver. Ed Gallagher served as honorary coach for the 1936 U.S. Olympic team. Scientific approach to wrestling Using his engineering knowledge, Gallagher studied leverage, and how it applied to wrestling. Gallagher selected over 400 wrestling holds, and expected each of his wrestlers to master about 200. Gallagher openly shared what he learned with others. He and his teams often conducted wrestling demonstrations before or after dual meets. In 1939, he and his Cowboy wrestlers demonstrated holds in a three-page photo-article in Life magazine. He also wrote two instructional books, "Amateur Wrestling" and "Wrestling." Later life In the 1930s, Gallagher was diagnosed with Parkinson's Disease. In 1938, he retired as director of physical education but remained on as wrestling coach. February 3, 1939 was "Gallagher Day" at Oklahoma A&M and Stillwater, the day the new 4-H Club and Student Activity Building was dedicated. Soon afterward, it was renamed Gallagher Hall in Gallagher's honor. This structure has since been renamed Gallagher-Iba Arena to honor both Gallagher and Henry Iba, long-time basketball coach at Oklahoma A&M/State. The Cowboys' first season in the new arena was the last to be coached by Gallagher. He died on a vacation to Colorado on August 28, 1940. His funeral was held in the arena. Honors In 1976, Edward C. Gallagher was inducted into the inaugural class of the National Wrestling Hall of Fame
