Frank Kellogg Richardson (February 13, 1914 – October 5, 1999) was an Associate Justice of the California Supreme Court.
Born in St. Helena, California, Richardson graduated from Germantown High School in Philadelphia, Pennsylvania. He attended the University of Pennsylvania his freshman year but transferred to Stanford University, where he earned an A.B. with distinction in political science in 1935 and was elected to the Phi Beta Kappa honor society. He then went on to earn his LL.B. from Stanford Law School in 1938.
After being admitted to the California State Bar in 1938, Richardson entered private practice in Oroville sharing office space with retired Butte County Judge Hirman Gregory. While working as an usher at the local Methodist church, Richardson met Betty Kingdon, whom he would marry on January 23, 1943. Their marriage would produce four sons and last for 56 years until Frank Richardson's death in 1999.
During World War II, Richardson entered the U.S. Army, serving from 1942 to 1945 in Europe. In 1944, Richardson, a second lieutenant in Army Intelligence, was assigned to the top secret Ultra Project at Bletchley Park (north of London), where he learned that British Prime Minister Winston Churchill was scheduled to address the British Parliament on the status of the war effort in the Balkans. Wearing his US Army uniform and using identification papers from the U.S. Embassy, Richardson talked his way through multiple layers of security and was escorted to a seat in the Distinguished Visitors Gallery next to the Archbishop of Canterbury. By the end of the war, he was a First Lieutenant and had been awarded two service stars.
