Peterson, a San Diego businessman and restaurateur, opened the first Jack in the Box restaurant on the main east-west thoroughfare leading into San Diego, at 6270 El Cajon Blvd. Perhaps by coincidence, 1951 was the same year that publisher Merriam-Webster first referenced the term "fast-food."
1960	San Diego Commissary Company, headed by Mr. Peterson, acquired Jack in the Box, Inc.
