During World War II, residential commissions stopped. Wright did manage to receive a commission to design two buildings for the Kingsbury Ordnance Plant 20 miles south of Long Beach. In 1946, Wright published a biography of his father, "My Father Who Is on Earth". Wright and Hazel Lundin were divorced in 1942, and Wright married Frances Welsh in 1946. Wright designed a home for him and his third wife in Del Mar, California, later that year. He also resumed his architectural toy designs, designing Wright Blocks and Timber Toys. He designed nearly four dozen houses in California until his death on December 20, 1972, eight days after his eightieth birthday.
