Barbara Evelyn Nicholson (1906 – 1978) trained at the Royal College of Art, graduating in 1923. She began her artistic career as a medical illustrator and was a founder member of the Medical Artists Association, where she is recorded as serving on an exhibition committee in October 1949. By 1951, she had illustrated G.F. Gibberd, A short textbook of midwifery (2nd ed., London: J. & A. Churchill, 1941) and Philip Wiles, Essentials of orthopaedics (London: J. & A. Churchill, 1949). The Medical Artists Association records last list her, in 1951. In the 1950s her focus moved to botanical subjects and from the late 1950s – 1970s she was a prolific botanical illustrator.
