there were only a few groups in California that promoted "vocational training" for police. Two of these groups, in coordination with San Jose State College, obtained partial funding in order to conduct a series of two-week summer sessions. Three seminars were held in the summer of 1937 at San Jose. These seminars were named the "California Technical Institute for Peace Officer Training".
Frank Gompert was a laboratory expert for the Los Angeles County Sheriff's Department and an instructor at the school. At the class graduation dinner, he was selected as chairman of a group of graduates who proposed establishing a “brotherhood or fraternity” of trained officers that could promote the learning they had acquired in the school. Earl Warren, (later Governor of California and Chief Justice of the United States Supreme Court), saw the proposed organization as a valuable contribution to peace officers in the state. He provided the necessary resources and facilities as well as legal assistance.
