Paul Mason

Professional career Paul Mason served for many years in California government: Chief Assistant Secretary of the California Senate (1929–32); Chief, Division of Driver's Licenses (1937–53); Director of Motor Vehicles (1954–58); and Legislative Secretary to California Governor Goodwin Knight (1954–58). Mason is known primarily for two published works: The Constitutional History of California and the Manual of Legislative Procedure.

According to the National Conference of State Legislatures (NCSL), Mason's Manual has become the most widely used legislative procedure guide in the U.S., currently in use by 77 of the 99 state legislative bodies in the United States.

Before Mason's death in 1985, he assigned the copyright of his manual to the NCSL. The book is edited by an NCSL commission every few years to keep it up-to-date with the latest legal precedents.

Mason's other seminal work was his Constitutional History of California. In this essay, Mason examines the Spanish alcalde origins of California's legal system, through the Mexican era, up through the framing of the Constitutions of 1849 and 1879.

In the California Senate, Mason served for many years under longtime Secretary of the Senate Joseph Beek.
