A rep said that he died after a short battle with leukemia.
"Our dad always saw himself as The Bright Knight, and aspired to make a positive impact on his fans' lives", West's children said in the statement.
His death was confirmed on his official Twitter account with a post credited to the West family. West in recent years did a range of voice-over work, on such shows as Adult Swim's "Robot Chicken" and Disney Channel's "Jake and the Neverland Pirates".

West made his feature debut in 1959's "The Young Philadelphians", starring Paul Newman.
