Magdalen Dorothea Vernon (1901–1991) was a British experimental psychologist who published her research widely and trained many PhD students.
Maggie (as she was known) and her brother Philip, were born in Oxford to Katharine Dorothea Ewart and Horace Middleton Vernon.
She attended Oxford High School and then enrolled in Newnham College, Cambridge on a scholarship, earning her MA in 1926 and Sc.D in 1953.
Her following book on the subject was widely read and she worked with Scottish psychologist Kenneth Craik as well, which resulted in joint papers on dark adaptation.
According to an obituary by Davis, "Her presence greatly enhanced the reputation of the department and it is remarkable how many eminent psychologists took their PhDs under Magdalen Vernon's supervision".
