Alan Sterling Parkes

Sir Alan Sterling Parkes, FRS, CBE (10 September 1900 – 17 July 1990) was an English reproductive biologist credited with Christopher Polge and Audrey Smith for the discovery that spermatozoa can be protected against induced damage induced by freezing and low-temperature storage using glycerol. This work enabled the development of the field of cryobiology.

Hall was educated at Willaston School.

He published on the reproductive effects of X-rays on mice, hormonal control of secondary sexual characteristics in birds, and aided Hilda Bruce in research that established the Bruce effect.

He was a member of the American Association for Anatomy.

In 1962, Parkes was awarded the Cameron Prize for Therapeutics of the University of Edinburgh. Provided by Wikipedia
