1994: Death of Charles Tevis - first DEFSMAC director

Mr. Charles Tevis was a pioneering advocate for space-based signals intelligence collection at NSA in the late 1950s. He advocated using satellites to collect telemetry from foreign strategic weapon systems, which resulted in the deployment of several novel space-based signals intelligence collection systems. In the late 1960s, Mr. Tevis also was instrumental in founding the Defense Special Missile and Astronautics Center (DEFSMAC). This made integrated intelligence available to policymakers. In 1964, Tevis was appointed DEFSMACās first director by the secretary of defense. Charles Tevis was inducted into the NSA/CSS Hall of Honor in 2002. He passed away #OTD in 1994.
