A member of a prominent family, Cadet Sidney J. Brooks, Jr. became the first San Antonian to lose his life in World War I activities. He was killed when his JN-4 biplane crashed on his final return training flight from Hondo airfield to Kelly Field (now Kelly Air Force Base), Texas. Cadet Brooks was posthumously awarded his aviator's wings and commissioned at the request of the City Council. Brooks Field (now Brooks Air Force Base), San Antonio, was named in his honor. In November 1987 the Sidney J. Brooks Jr. Memorial Park and monument was dedicated on the base. He was reinterred, and his original gravestone transferred, from the Alamo Masonic Cemetery near downtown San Antonio, to the park on November 11, 1993.
