Gary Allen

As a student, Allen majored in history at Stanford University in Palo Alto, California, and studied as well at California State University in Long Beach. He was a prominent member of Robert W. Welch, Jr.'s John Birch Society, of which he was a spokesman. He contributed to magazines such as Conservative Digest and American Opinion magazine since 1964.

In 1971, Allen wrote with Larry Abraham a book titled None Dare Call It Conspiracy (prefaced by U.S. Representative John G. Schmitz of California's 35th congressional district and the nominee of the American Independent Party in the 1972 U.S. presidential election). It sold more than four million copies during the 1972 presidential campaign opposing Nixon and U.S. Senator George S. McGovern.

In this book, Allen and Abraham assert that the modern political and economic systems in most developed nations are the result of a sweeping conspiracy by the Establishment's power elite, for which he also uses the term Insiders.
