Since World War II, Barry Goldwater and Ronald Reagan have been America's predominant conservative politicians, but William F. Buckley was the intellectual who founded the movement. Buckley was a lonely voice in the 1950's, but he became a familiar one. He was founder of the National Review and host of Firing Line on public TV. Ill with emphysema, Buckley died at work in Stamford, Connecticut at the age of 82. George Nash, whose books include The Conservative Intellectual Movement in American Since 1945, is president of the Philadelphia Society, a conservative group Buckley founded.
