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.

Mitral valve from below, from above, wall of l<eft> ventricle, l<eft> atrium from above Lettering inscribed in black ink as key, typed accopmanying note with patient history includes post-operative infectious pneumothorax followed by fatal heart failure. At autopsy, it was discovered that division of the mitral, attempted at valvotomy was unsuccessful, since the calcified chordae tendinae were not materially altered. This created the fish mouth effect shown in the right image. This mass of calcerous material around the septal chordae, in particular, had prevented adequate splitting of the commissure Bears number: 331/1953
