Dame Mary Lucy Cartwright December 17, 1900 - April 3, 1998 During the 1940's Mary Cartwright worked with John Littlewood on the solutions of the Van der Pol equation and discovered many of the phenomena that later became known as "chaos". In his review of Ian Stewart's book, Nature's Numbers , Dyson writes about this work Cartwright had been working with Littlewod on the solutions of the [ Van der Pol] equation, which describe the output of a nonlinear radio amplifier when the input is a pure sine-wave. The whole development of radio in World War Two depended on highpower amplifiers, and it was a matter of life and death to have amplifiers that did what they were supposed to do. The soldiers were plagued with amplifliers that misbehaved, and blamed the manufacturers for their erratic behavior. Cartwright and Littlewood discovered that the manufacturers were not to blame. The equation itself was to blame. They discovered that as you raise the gain of the amplifier, the solutions of the equation become more and more irregular. At low power the solution has the same period as the input, but as the power increases you see solutions with double the period, and finally you have solutions that are not periodic at all. Cartwright had a distinguished career in analytic function theory and university administration, publishing numerous papers on classical analysis, differential equations and related topological problems. In 1947 Cartwright became the first woman mathematician to be elected as a Fellow of the Royal Society of England. She was elected President of the London Mathematical Society in 1951, received the Sylvester Medal of the Royal Society in 1964, the De Morgan Medal of the London Mathematical Society in 1968, and in 1969 became Dame Mary Cartwright (the female equivalent of a knighthood).

When she was eleven years old, she was sent away to school, first attending Leamington High School, then later attending the Godolphin School in Salisbury. Her best subject at school was history but it had the disadvantage of requiring much effort in learning endless lists of facts. When she was encouraged in her studies of mathematics in her final year at school, Mary realised that it was a topic where one could succeed without the long hours of learning facts. It became the topic that she wanted to study at university. In October 1919 Cartwright entered St Hugh's College in Oxford to study mathematics. At that time she was one of only five women in the whole university who were studying mathematics. This was a difficult time to enter university since, World War I having just ended, there were large numbers of men returning from the army who were either restarting the university studies they had begun before the war or were taking up their studies for the first time. The lecture halls were crowded and often Cartwright had to copy up notes of lectures which she could not get into because of the crowds.

Obituaries Electronic Telegraph Saturday 11 April 1998 Dame Mary Cartwright Mistress of Girton whose mathematical work formed the basis of chaos theory DAME Mary Cartwright, who has died aged 97, was one of most eminent British mathematicians of the century, and between 1949 and 1968 Mistress of Girton College, Cambridge - the longest tenure in the college's history. Mary Lucy Cartwright was born on December 17 1900 at Aynho, Northamptonshire, where her father was curate and later rector. At first educated by governesses, Mary was later sent away to various schools, including Godolphin, in Salisbury. Her younger brother Frederick, a Rugbeian, would end his career as deputy chairman of the British Steel Corp-oration. In 1919 Mary Cartwright went up to St Hugh's College, Oxford, to read mathematics. Owing to the gaps in her schooling she felt herself ill-prepared for the course, and in 1921 obtained only a Second in Moderations. Tempted to change to history, she rejected this option because it seemed to entail rather too much work. Her breakthrough as a mathematician came in her third year, when V C Morton, later professor of mathematics at Aberystwyth, suggested at a party on a barge in Eights Week that she should attend evening classes of the great G H Hardy, then Savilian Professor of Geometry. Mary Cartwright went on to obtain a First in 1923, only the second year in which women took Final degrees at Oxford.

On reading her papers on these latter applications, it is clear that she had a deep and abiding appreciation for the physical phenomenon as well as its underlying mathematics. Her prescient work (especially with Littlewood) anticipated some of the geometrical ideas that are fundamental to chaotic dynamics and represents an important milestone in the evolution of our thinking about dynamical complexity."

Continue article Advertisement M.C. I am descended from the Cartwrights of Aynho in Northamptonshire. Richard Cartwright purchased the manor house and its grounds in 1616. His son John, who married the daughter of the attorney general to Charles I, remained a Roundhead, and stayed in London during the Civil War. During the War the Aynho Park Manor House was occupied by Cavalier soldiers and John's mother imprisoned in Banbury. John's only son William married Ursula, daughter of Fernando Fairfax. After their major defeat by Thomas Fairfax at the Battle of Nasby, the returning Cavalier soldiers burnt most of Aynho Park. My great-great-grandfather married Mary Catharine Desaguliers whose grandfather J. T. Desaguliers came over from France with his father, a Huguenot pastor, after Louis XIV revoked the Edict of Nantes in 1685. J. T. Desaguliers became Curator of the Royal Society and wrote books on physics. His son became a General in the Army and brought back stones with inscriptions praising Louis XIV which were inserted in the Wall at Aynho Park. My great-grandfather, William Randolph Cartwright lived in Rome for a time and then Florence, where he was a correspondent for the Spectator magazine. He returned to England and served as a liberal MP for Oxfordshire for more than forty years. He was married twice and had thirteen children, eight sons by his first wife and five sons by his second wife Julia Frances nee Aubrey.
