Paul Leventhal founded the Nuclear Control Institute in 1981 and serves as its President after having held senior staff positions in the United States Senate on nuclear power and proliferation issues.

He has prepared four books for the Institute and has lectured in a number of countries on nuclear issues, including as Distinguished Visiting Fellow at Cambridge University's Global Security Programme.

Mr. Leventhal organized the Institute's International Task Force on Prevention of Nuclear Terrorism, its conference in South America on averting a nuclear arms race between Argentina and Brazil, a coalition of eminent U.S. scientists and diplomats seeking a halt in further production of nuclear-weapon materials, and a working group of public interest organizations in Washington on    nuclear proliferation issues.

He served as Special Counsel to the Senate Government Operations Committee, l972-1976, and as Staff Director of the Senate Nuclear Regulation Subcommittee, l979-1981. He was responsible for the investigations and legislation that resulted in enactment of two landmark nuclear laws---the Energy Reorganization Act of 1974, replacing the Atomic Energy Commission with separate regulatory and promotional agencies, and the Nuclear NonProliferation Act of 1978, establishing stricter controls on U.S. nuclear trade to combat the spread of nuclear weapons. He also served as director of the Senate Special Investigation of the Three Mile Island Nuclear Accident, 1979-1980, and prepared the "lessons learned" legislation enacted in 1980 to require preventive measures and emergency planning for future accidents.

He holds a bachelor's degree in government, magna cum laude, from Franklin and Marshall College.
