Ned Doheny, his wife Lucy, and their five children moved into Greystone in October 1928. Four months later, on February 16, 1929, Doheny died in a guest bedroom in a murder-suicide with his close boyhood friend and personal confidential secretary, Theodore Hugh Plunkett. "On November 28, 1921,
Doheny (Sr.) signed a proposal to build the oil storage depot at Pearl Harbor in exchange for the Navy's crude oil. The very next day,
Fall called Doheny and told him to go ahead and said the "loan" they had talked about was due. Doheny then dispatched his son, Edward L. Doheny, Jr. and Doheny, Jr.'s employee and friend, Hugh Theodore Plunkett, to deliver the loan. The two men went to the brokerage house of Blair and Company withdrew one hundred thousand dollars in cash from Ned's account wrapped the money in paper and put it in a little black bag and took it to Fall in his apartment at the
Wardman Park Hotel in Washington. Later Ned Doheny claimed that Fall had given him a receipt for the "loan"." Doheny's widow, Lucy, remarried and lived in the house until 1955, when she sold the estate to
Paul Trousdale, who developed its grounds into
Trousdale Estates and sold the mansion to
Chicago industrialist
Henry Crown, who rented it to
film studios. In 1963 Crown planned to demolish the mansion and subdivide its lot. Beverly Hills stopped the demolition by purchasing the mansion in 1965. The estate became a city park on September 16, 1971, and on April 23, 1976, was added to the
National Register of Historic Places. The city leased the mansion to the
American Film Institute from 1965 to 1982 for $1 per year, hoping the institute would pay for repairs and upkeep. ==Current use==
