Elliot Richardson, American lieutenant and politician, 11th United States Secretary of Defense (d. 1999)
Elliot Lee Richardson (July 20, 1920 – December 31, 1999) was an American lawyer and public servant who was a member of the cabinet of Presidents Richard Nixon and Gerald Ford. As U.S. Attorney General, he was a prominent figure in the Watergate Scandal, and resigned rather than obey President Nixon's order to fire special prosecutor Archibald Cox.

Born in Boston, Richardson attended Harvard University. He served as Secretary of Health, Education, and Welfare from 1970 to 1973, Secretary of Defense from January to May 1973, Attorney General from May to October 1973, and Secretary of Commerce from 1976 to 1977. This distinction makes him one of only two individuals to have held four Cabinet positions within the United States government (the other being George Shultz). As of 2021 he is the last Republican to serve as Massachusetts Attorney General.
