Camelia Whitehurst (1871–1936) was born in Baltimore, Maryland, where she spent most of her life. She studied at Baltimore’s Charcoal Club with Samuel Whitman, and at the Pennsylvania Academy with William Merritt Chase and Cecilia Beaux. After completing her studies, she opened a studio in Paris and traveled through Europe. In 1920, she moved into her Baltimore studio.

She was a member of the National Association of Women Artists; the Grand Central Art Gallery; North Shore Art Academy; Springfield Art League; the Society of Washington Artist; and other arts organizations.

Camelia exhibited her works at various venues including the Pennsylvania Academy of Fine Arts, the Society of Washington Artists, Corcoran Gallery of Art, and the National Association of Women Painters and Sculptors. In 1924, Whitehurst participated in the first exhibition at the Baltimore Museum of Art to feature only works of art by women. The “Six Baltimore Women Painters” had exhibited earlier (c.1911-1912) in the Peabody Gallery; by the time of the 1924 exhibition The Six had become “The Six and One”.

Camelia Whitehurst was best known for her portraits of young children. I also found an example where one of her paintings had been used for a cover of The Literary Digest, so it seems that in her time she was considered a notable artist. https://www.periodpaper.com/products/1930-cover-literary-digest-gypsy-child-costume-fashion-kid-camelia-whitehurst-205236-yld6-018
