John Main Olguin was an American aquarium official who served as the museum director of the Cabrillo Marine Museum, which has since been renamed the Cabrillo Marine Aquarium, from 1949 until 1987, when he became director emeritus. Olguin has been called the "father of recreational whale watching", as he was the founder of the Cabrillo Whalewatch program and a founding member of the American Cetacean Society. Olguin was born in San Pedro, California, a port district and neighborhood of Los Angeles, on February 18, 1921. His father, Roy Olguin, had moved to southern California from Mexico in 1910 and married Josie Main, a woman from Long Beach, California, who became Olguin's mother. His ancestry also included some Chumash heritage. Olguin became a lifeguard beginning in 1937. Olguin graduated from San Pedro High School in 1941
