William Ruckelshaus
William Doyle Ruckelshaus (July 24, 1932 – November 27, 2019) was an American attorney and government official.
Ruckelshaus served in the Indiana House of Representatives from 1966 to 1968, and was the United States Assistant Attorney General for the Civil Division from 1969 to 1970. He was also the first Administrator of the US Environmental Protection Agency (EPA) from 1970 to 1973, after being nominated by Richard Nixon. He returned to the position from 1983 to 1985, as the fifth Administrator of the EPA, during the Reagan administration. In 1973, he was also the acting FBI Director.
While serving as US Deputy Attorney General in October 1973, in what became known as the "Saturday Night Massacre," Ruckelshaus and US Attorney General Elliot Richardson resigned from their positions rather than obey the order of US President Richard Nixon to fire the independent special prosecutor, Archibald Cox, who was tasked with investigating Nixon's role in the Watergate scandal.
