On February 2nd, 1946, ABC premiered a fifteen-minute serial from KGO in San Francisco called One out of Seven. It starred a twenty-five year old actor named Jack Webb.
He was born in Santa Monica, California on April 2nd, 1920 and grew up in a Bunker Hill boarding house run by his Irish and Native American mother Margaret. One of their tenants was a former jazz musician who gave Jack a record of Bix Beiderbecke's "At the Jazz Band Ball.” He became an instant fan.
He attended High School near downtown Los Angeles and St. John's University in Minnesota, where he studied art.
Following his World War II discharge from the US Army Air Corps he moved to San Francisco, where a shortage of radio announcers led to an opportunity.
