Sitter in 5 portraits
Cartwright was one of 5 women studying mathematics at St Hugh's College, Oxford and the first woman to receive a First class honours degree in the subject, in 1923. After teaching for several years, she returned to Oxford to research her doctorate and met John Littlewood, an external examiner who would become a lifelong collaborator. Together they researched non-linear differential equations and worked on solutions of the Van der Pol equation, laying the foundations of the chaos and catastrophe theory. Elected to a Yarrow Research Fellowship in 1930, in 1936 Cartwright became director of studies of mathematics at Girton College, Cambridge. Between 1960-1963 she was the president of the London Mathematical Society.
