The St. Francis Dam was a 200-foot high concrete gravity-arch dam built between 1924 and 1926 in St. Francisquito Canyon (near present-day Castaic and Santa Clarita). The dam collapsed on March 12, 1928 at two and a half minutes before midnight. The resulting flood killed more than 600 residents plus an unknown number of itinerant farm workers camped in San Francisquito Canyon, making it the 2nd greatest loss of life in California after the 1906 San Francisco earthquake. It is considered the worst American civil engineering failure in the 20th century.
Dr. St. Louis Albert Estes (1876-1951) was an American doctor and the author of Raw Food and Health. He lived in Van Nuys, California in the late 1920s and early 1930s, and had 3 children with his first wife in the 1910s, 12 children with his second wife in the 1920s and 1930s.
