[6] Smith encouraged Davison to pursue a career in medical illustration, commissioning her to produce anatomical drawings for him.
[7] She produced illustrations for orthopaedic surgeon Sir Harry Platt, Professor of Anatomy G.A.G Mitchell, and obstetrician Daniel Dougal.
[7] Davison also produced illustrations for notable publications, including Mitchell's Anatomy of the Autonomous Nervous System and Israel's Atlas of Pathological Haematology.
[9] In 1939, the University of Manchester sought to offer Davison a formal contract as a Medical Artist, but the onset of the war prevented this from happening until 1945.
[5][10] Davison used the 'Ross board technique', developed by Max Brödel while at Johns Hopkins School of Medicine, and introduced to British artists by Audrey J.
Davison always emphasised the capacity of medical illustration to clarify and draw attention to the complex and obscure, as opposed to photographs which could merely copy.
[11]From the early 1940s, Davison trained a large number of aspiring medical artists in Manchester,[6] a condition of her employment at the Royal Infirmary.
[6] In 1927, she published Days and Ways of Early Man, which one review called "a marked advance in the art of popular presentation of difficult and highly technical matter".
[14] In 1934, she published Men of the Dawn: the Story of Man's Evolution to the End of the Old Stone Age (part of the Thinker's Library).
