Gloria Parker (née Rosenthal; August 20, 1921April 13, 2022) was an American musician and bandleader who had a radio show during the big band era. The Gloria Parker Show was broadcast nightly from 1950 to 1957, coast to coast on WABC. She played the marimba, organ, and singing glasses (glass harp). Dubbed Princess of the Marimba, she conducted the 21-piece Swingphony from the Kelly Lyceum Ballroom in Buffalo, New York. This was the largest big band led by a female bandleader. Edgar Battle and Walter Thomas were arrangers for the Swingphony. Early life Parker was born in Brooklyn on August 20, 1921. Her father, Jack, was the owner of a garage; her mother, Rose (Glickman), was a violinist with Mark Warnow & the Hit Parade Orchestra. Her grandfather immigrated to the United States from the modern-day Czech Republic, and taught her how to play glasses. She started learning the violin at the age of four or five, playing a quarter-sized version of the instrument at the Brooklyn Academy of Music during the latter year. Career Parker worked as a songwriter, bandleader and musician. She performed with her orchestras playing the marimba, glass harp or musical glasses, piano, organ, violin, viola, vibraphone, xylophone, guitar, drums and all Latin percussion instruments. The big band era included a musicians' recording ban from August 1942 to November 1944. The union that a majority of musicians belonged to did not allow its members to record until the record companies such as CBS agreed to pay them each time their music was played on the radio. This happened after an earlier ban of ASCAP songs from radio stations which led to the demise of this style of swing music. Parker emerged as a spokesperson for musicians and earned the title "Famous One Share Stockholder" in her battle for musician rights with CBS, RCA, and Time Inc. The national media would anxiously await Parker's head to head confrontations with CBS founder William S. Paley and RCA chairman of the board David Sarnoff at the annual stockholder meetings. Starting in 1952, Parker had her own program, The Gloria Parker Show, on WJZ-TV in New York City. It featured her all-female Swingphony, the largest big band led by a woman. During the early 1950s, she hosted a radio program with Vincent Lopez from the Taft Hotel in Manhattan called Shake the Maracas. She hosted an evening broadcast on WOR
