Ralph Jester (July 10, 1901 – September 25, 1991) was an American costume designer, sculptor, and artist. Born in Tyler, Texas, he graduated in 1919 from the Terrill School, the forerunner to St. Mark's School of Texas. He was educated at Yale, where he was an editor of the campus humor magazine The Yale Record.After graduating from Yale and studying at the American Academy in Fontainebleau, France, Jester moved to Hollywood. By 1931, he was working as an art director and costume designer for Cecil B. DeMille and Paramount Pictures. For much of his career, his closest collaborator was Edith Head.For DeMille's epic Cleopatra (1934), Jester designed Claudette Colbert’s marble throne as well as the busts of Colbert and her co star, Warren William. He is perhaps best known professionally as one of the costume designers of The Ten Commandments (1956). He also worked on such films as Omar Khayyam (1957) and The Buccaneer (1958). Earlier, in 1938, Frank Lloyd Wright had designed a circular home for Jester in Santa Clara, California. Never built but considered a masterpiece of design, the house was Wright's first foray into using the circle in his buildings. Wright's Guggenheim Museum would not be built for another 20 years. Jester would go on to build a more traditional, Wright-designed house, in Ranch Palos Verdes, California.
