After a stage career in the 1920s, she returned to films as Ann Rutledge in D. W. Griffith's Abraham Lincoln (1930). She mostly played supporting roles as the heroine's no-nonsense friend, but with her brought southern accent and her peroxide blond hair, she gave one of the best performances of a wise-cracking, but not so brought chorus girls in "42nd Street". But perhaps best remembered is her hair-pulling fight in "Destry Rides Again" with Marlene Dietrich about the Mischa Auer's trousers. Other Films to watch include Dangerous Female (1931); Private Lives (1931); Red-Headed Woman (1932); The Merry Widow (both 1934 and 1952); Broadway Melody of 1936 (1935); Born to Dance (1936); On Borrowed Time (1939); The Bank Dick (1940); Road to Zanzibar (1941); Mad Doctor Of Market Street(1942);This Is the Army (1943). Tragedy struck in 1946 when she almost died in 1946 when her mother committed suicide by turning on the gas. She returned to films with With a Song in My Heart (1952); and The Parent Trap (1961). She won a Tony in 1956 for "The Ponder Heart" In 1962 she was nominated for the Academy Award as best supporting actress in "Summer and Smoke". Una Merkel died on 2 January 1986 in Los Angeles, California.

Claire Dodd

 Dorothy Anne Dodd was born on December 29, 1908 in Des Moines, Iowa where her mother was on a trip. This did not appeal to her so she said she was born in Little Rock Arkansas where she was raised. Her father was a doctor who abandoned her and her mother before she was ten years old. Her mother suffered from tuberculosis and Dorothy was forced to support her. She went to New York at the age of fifteen, lied about her age, and joined the Zeigfeild Follies where she was eventually discovered by Darryl F. Zanuck. He brought her to Hollywood and shepherded her throughout most of her career. She worked for Warner Brothers, Paramount, and Universal. She played the "other" woman and could not be cast as a "dumb blond" because of her cerebral nature and demeanor. Good friends with 'Betty Davis' with whom she worked in "Ex-Lady", she worked with everyone from Bogart and Flynn to Stanwyk, and Cagney. She played "Della Street" in one of the original Perry Mason thrillers "The case of the Velvet Claw" where she was the only Della Street to marry a Perry Mason. She played the female lead in "In the Navy" against Dick Powell but received lesser billing, which she claimed was a standard procedure practised on her in recompense for her aloofness. In fact, her nickname was "Ice Bucket". She worked in almost sixty films in twelve years from 1930 to 1942. She quit films and married H. Brand Cooper to whom she gave and raised four children. She undertook and completed this phase of her life after she was forty years old, giving bith to her last child at the age of forty-seven. She was to say the least a remarkable woman. She died in our family home from cancer on November 23, 1973.
