Cooke was born in
Hulme in Lancashire in 1867 to John and Eliza Anderson (born Jackson) Cooke. Following private education she went to
Manchester High School for Girls where she was identified as academic. She could attend
Owens College, Manchester (by then part of the
Victoria University), since the college had allowed women to attend a few years before and she was able to live with her parents. The university had limited provisions for co-educational education. She liked history and she won the Bradford history scholarship in 1888 which assisted her in gaining not only a first class degree in history in 1890, but also the
Jones fellowship. The fellowship funded post-graduate research which resulted in a publication in 1893 of what became the standard account of early
Cistercian monasteries. 1893 also saw Cooke become the first woman lecturer working for
Thomas Frederick Tout at her alma mater and the first recipient of a master's degree from Owens College: the university did not award history doctorates at that time. She also took various roles to assist female students who were following her path and she became a governor of the university and assistant tutor to women students in 1897. Cooke travelled and cycled and supported women's suffrage. A notable academic task was her compilation of an index to
Earl Spencer's Althorp Library. It had been the most expensive library collection ever purchased when the millionairess
Enriqueta Rylands paid £210,000 for it. The indexing was undertaken at the request of Mrs. Rylands, for the nascent
John Rylands Library. In 1901 Cooke moved to Cardiff where she lectured in the history department of the
University College of South Wales and Monmouthshire. She was there until 1903 when she returned to cataloguing libraries. In this case it was Lord Acton's Library in Cambridge which consisted of over 60,000 books. From 1905 she returned to teaching, this time it was modern history at Cambridge University's
Newnham College. After the war her health deteriorated which may have been due to her work as a Leeds policewoman during the conflict. After a lengthy convalescence she returned to Newnham College where she was director of studies in the history department. Cooke retired in 1927 where she lived with a companion. In 1934 she became an invalid and she was cared for by nuns in Manchester until her death in 1940. ==Legacy==
