Anna McClean Bidder

Anna McClean Bidder (4 May 1903 – 1 October 2001 ) was an English zoologist and academic. She was co-founder and first President of Lucy Cavendish College, Cambridge. Her mother, Marion Bidder, had been a pioneering woman student before teaching physiology and botany at Girton and Newnham colleges.

Bidder was educated at the Perse School for Girls, and then went on to study Zoology for a year at University College, London. She returned to Cambridge in 1922 to read Natural Sciences at Newnham College. Her elder sister had chosen to study at Girton, the only other women's college in Cambridge at the time, and their mother wished to send one daughter to each. Bidder changed her subject to Zoology partway through her studies, and graduated in 1926.

This led eventually to the founding of the Lucy Cavendish Collegiate Society for mature female students in 1965. Bidder was President of the college from its foundation until her retirement in 1970.

Her Quaker beliefs led to her involvement in the publication of the somewhat controversial 1963 pamphlet, Towards a Quaker View of Sex, which aimed to take a new view of the changing sexual mores of the time.
