William Flynn Martin
William Flynn Martin (born October 4, 1950) is an American energy economist, educator and international diplomat. Martin served as Special Assistant to President Reagan for National Security Affairs, Executive Secretary of the National Security Council in the West Wing of the White House and Deputy Secretary of the Department of Energy during the Ronald Reagan administration. He was President of the Council of the University for Peace, appointed to the Council by Secretary General of the United Nations Kofi Annan and served as the Executive Director of the Republican Platform Committee during the re-election bid of George H.W. Bush. He has held senior appointments and advisory positions under several Presidents including: Ronald Reagan, George H.W. Bush and George W. Bush.Martin was born in Tulsa, Oklahoma. He achieved his Bachelor of Science from the Wharton School of the University of Pennsylvania in 1972 and his Master of Science from MIT in 1974. His master's thesis was the basis of an article he co-authored with George Cabot Lodge in the March, 1975 Harvard Business Review entitled Our Society in 1985: Business May Not Like It [1].
