Sara Berner (born Lillian Ann Herdan; January 12, 1912 – December 19, 1969) was an American actress. Known for her expertise in dialect and characterization, she began her career as a performer in vaudeville before becoming a voice actress for radio and animated shorts. She starred in her own radio show on NBC, Sara's Private Caper, and was best known as telephone operator Mabel Flapsaddle on The Jack Benny Program. Columnist Erskine Johnson described Berner in 1944 as "the most famous voice in Hollywood." Early life and career Born Lillian Ann Herdan in 1912 in Albany, New York, she adopted her stage name by combining her mother's first name (Sarah) and her maiden name of Berner. She was the oldest of four children, and her family relocated to Tulsa, Oklahoma when she was a teenager. She became interested in performing after watching silent movies and vaudeville shows at a theater and then imitating scenes in front of the women's restroom attendant. Berner performed in an adaptation of Abie's Irish Rose after graduation, and she studied drama for two years at the University of Tulsa. She and her family then moved to Philadelphia, Pennsylvania, where she worked in a Wanamaker's department store until she was fired for mimicking a customer. Berner hosted her own fifteen-minute program (written by Arthur Q. Bryan) thereafter on a local radio station, then returned to New York City in hopes of pursuing a show-business career. She worked in a Broadway millinery in the meantime, and studied dialect by observing customers' Brooklyn accents. She sneaked out during a shift to audition for Major Edward Bowes' amateur hour, and was hired the next day. Beginning in 1937, Berner toured the country as part of Bowes' sixteen-member "all-girl unit" of vaudeville acts over the next four years, and created a gimmick of a fired saleslady who performed imitations of celebrities such as Mae West and Katharine Hepburn. Career Radio After the Major Bowes tour ended, Berner began working in network radio in Hollywood, with recurring roles on Fibber McGee & Molly and The George Burns and Gracie Allen Show. On The Jack Benny Program, she voiced one-time parts before joining the principal cast as the recurring characters of Jack Benny's girlfriend Gladys Zybisco, and wisecracking telephone operator Mabel Flapsaddle, who gossiped about Benny with her cohort Gertrude Gearshift (Bea Benaderet), while Benny waited impatiently on the other end of
