Evelyn Marion Hickmans (9 April 1882[1] – 16 January 1972[2]) was a pioneer in developing a treatment for phenylketonuria together with Horst Bickel and John Gerrard.
Their work on fat absorption in cases of coeliac syndromes, would be further clarified by work undertaken by Parson's successor, Professor J. M. Smellie and a team that would include John Gerrard and Charlotte Anderson.
Hickmans came to notice when she, Horst Bickel and John Gerrard were persuaded by a persistent mother to help her daughter who was suffering from phenylketonuria.
They created a diet that was low in phenylalanine and the daughter's condition improved.
[3] In 1962, she and her team were awarded the John Scott Medal for their invention of a method for controlling phenylketonuria.
