The son of a sea captain, Theodore Roberts was a veteran stage actor, making his first appearance in 1880. Often referred to as the "Grand Duke of Hollywood," Roberts was a regular on the Cecil B. DeMille team and appeared in 23 of DeMille's films. He is best remembered for his role as Moses in DeMille's The Ten Commandments (1923). A well-known and well-loved actor, his funeral in Westlake Park (he died from uremic poisoning) was attended by nearly 2,000 people. However, Roberts felt so much bitterness in his heart for his immediate relatives that he bequeathed his estate to a nephew (a commercial illustrator) in New York. The estate was valued at nearly $20,000, including a yacht valued at $10,000. Several of Roberts' personal items were left to his friends William C. de Mille and his brother Cecil. Roberts claimed that during the worst times of his life, no one in his family offered a word of sympathy or any help at all. His only request was that he be laid to rest next to his beloved wife Florence Smythe, who passed away in 1925.
