Doctor Frederick Bartlett will be best remembered as an eminent research psychologist. He attained a first class degree in Moral Sciences in 1914 at the age of 28.

In the same year as his graduation and appointment as an Assistant in Experimental Psychology, war broke out and all of his seniors in Cambridge left for war service. Bartlett was ineligible for service due to a heart condition (he tried to enlist three times), and so he was appointed Temporary Director of the department. This resulted in the unheard of event in his almost immediately promotion from undergraduate student status to head of Psychology at Cambridge.
