CHEVALIER, Charlotte Bergersen

Charlotte Bergersen Chevalier was an American pianist, composer, piano teacher, and music educator, born in Chicago on 14 September 1926. She taught piano for many years and headed the Children’s Department of the American Conservatory of Music in Chicago. She was also an active concert pianist in the Chicago/Highland Park area, appearing regularly in solo and chamber-music programmes. Scribd
Music reference works explicitly identify her as a composer, although I have not found a reliable online catalogue giving titles of her original compositions. Archival records document her extensive activity as a pianist, including performances into the late 1980s.
