Elvia Allman (September 19 1904, Enochville, North Carolina – March 6 1992, Santa Monica, California) was a character actress and voice over performer in Hollywood films and television programs for over 50 years. She is best remembered for her semi-regular roles on The Beverly Hillbillies and Petticoat Junction and for being the voice of Walt Disney's Clarabelle Cow. Allman's first known credit as a voice performer for cartoons was in 1936 with the Porky Pig cartoon Porky's Moving Day. She may have originated the character of Clarabelle Cow prior to this, but there are no records indicating which specific cartoons she voiced Clarabelle in (Clarabelle Cow was featured in 28 Disney cartoons from 1928 to 1942). In 1937 Allman voiced the title role in the cartoon "Little Red Walking Hood", a spoof of Little Red Riding Hood. Allman made her film debut as an actress in 1940s Road to Singapore in an unbilled bit as a homely woman pursuing Bob Hope. The role was an unbilled bit like the majority of Allman's motion picture appearances in the 1940s. She worked most successfully during this period as a radio comedienne playing assorted guest parts, typically as a shrewish woman. One of her more steady radio gigs was on the Blondie radio series in the part of "Cora Dithers", the domineering wife of Dagwood Bumstead's boss. In 1957, she reprised her role of "Cora Dithers" in a short-lived TV adaption of Blondie. She also appeared on seven episodes of the series The Jack Benny Show, having worked often with Benny on his radio program in the 1940s and 1950s. (via Wikipedia)
