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).
