The first Science Advisor, Vannevar Bush, chairman of the Office of Scientific Research and Development, served Presidents Franklin Delano Roosevelt and Harry S. Truman from 1941 to 1951.
This committee continued under Presidents Dwight D. Eisenhower, John F. Kennedy, Lyndon B. Johnson, and Richard M. Nixon until 1973.
The current advisor is Arati Prabhakar, who has served as the 12th director of the White House Office of Science and Technology Policy (OSTP) since October 3, 2022.
The office was moved to the White House on November 21, 1957, by President Dwight D. Eisenhower to provide advice and recommendation in response to the Space Race started by the USSR's launch of the first artificial Earth satellite, Sputnik 1.
President Richard M. Nixon eliminated the PSAC in 1973, rather than appointing a replacement for his second Science Advisor, Edward E. David Jr., who resigned.
