Who is Frank S. Petersen?

Frank S. Petersen was a northern California jurist and politician who represented California's 4th State Senate district from 1963 to 1966 and served as a California Superior Court Judge for Del Norte County from 1966 to 1988.

Petersen was born June 20, 1922, in a logging camp near Elk, Mendocino County, California, and grew up in nearby Fort Bragg, California. He enlisted in the United States Navy during World War II, after which he received an associate degree from Santa Rosa Junior College in 1948 and a J.D. from the University of San Francisco in 1951. After working in a private practice and the county district attorney's office, he became the district attorney for Mendocino County in 1960. During his term as D.A., he became embroiled in a controversy called the "War of the Warrants" that began with a domestic abuse case, led to the issuance of 57 arrest warrants, and ended with the conviction of four people, two of them sitting judges, for obstruction of justice.

In 1962, Petersen ran for office as a California State Senator for California's 4th State Senate district, which at that time covered both Mendocino and Lake Counties.
