Vivian Vance (born Vivian Roberta Jones, July 26, 1909 – August 17, 1979) was an American television and theater actress and singer. Vance is best known for her role as Ethel Mertz, sidekick to Lucille Ball on the American television sitcom I Love Lucy, and as Vivian Bagley on The Lucy Show.

Born in Cherryvale, Kansas, Vance was the second of six children born to Robert and Euphemia Jones. When she was six years old her family moved to Independence, Kansas, where she eventually began her dramatic studies at Independence High School under the tutelage of Anna Ingleman, the drama instructor. Her love of acting clashed with her mother's strict religious beliefs, and it wasn't too long before Vance, nicknamed "Viv" by friends, became very rebellious, often sneaking out of her bedroom and staying out after curfew. She soon changed her surname to Vance (after folklorist Vance Randolph) and moved to Albuquerque, New Mexico to find work as an actress. Vance was a founding member of the Albuquerque Little Theatre, where she appeared in many plays including, This Thing Called Love and The Cradle Song. The local theatre community helped pay her way to New York to study under Eva Le Gallienne.

She was still making films in the 1960s and 1970s. In 1962, Ball became the first woman to run a major television studio, Desilu, which produced many successful and popular television series.

Joan Alexandra Molinsky (born June 8, 1933), better known by her stage name Joan Rivers, is an American television personality, comedian, and actress. She is known for her brash manner; her loud, raspy voice with a heavy New York accent; and her numerous cosmetic surgeries. Rivers' comic style relies heavily on her ability to poke fun at herself and other Hollywood celebrities.

Joan Rivers was born Joan Alexandra Molinsky in Brooklyn, a borough of New York City, the daughter of Russian Jewish immigrants Beatrice (née Grushman; January 6, 1906 – October 1975) and Meyer C.

She attended Connecticut College between 1950 and 1952 and graduated from Barnard College in 1954 with a bachelor-of-arts degree in English literature and anthropology. Before entering show business, Rivers worked at various jobs such as a tour guide at Rockefeller Center, a writer/proofreader at an advertising agency and as a fashion consultant at Bond Clothing Stores. During this period, the agent Tony Rivers advised her to change her name, so she chose Joan Rivers as her stage name.
