During the 1970s and 80s, the magazine's contributors included Milton Friedman, Murray Rothbard, Thomas Szasz, and Thomas Sowell. In 1978, Poole, Klausner, and Machan created the associated Reason Foundation, in order to expand the magazine's ideas into policy research. Marty Zupan joined Reason in 1975, and served through the 1980s as managing editor and editor-in-chief, leaving in 1989.
