Birth & DeathMary Lucy Cartwright was born Decemeber 17, 1900 in Aynho, England. Mary died April 3, 1993 in Cambridge, England.

FamilyMary Cartwright had four siblings. Three brother and one sisters; John, Nigel, Jane, and William.Mary's Father, William Cartwright, was a Vicar at Aynho. Which is a priest at a church in England. Her mom was didn't work.

ImpactIn 1930 she was awar­ded her thes­is, “The zer­os of in­teg­ral func­tions of spe­cial types,” was pub­lished in two parts in the Quarterly Journ­al of Math­em­at­ics, vol. 1 (1930) and vol. 2 (1931). Dur­ing her ca­reer, Cartwright pub­lished over 100 pa­pers in clas­sic­al ana­lys­is, dif­fer­en­tial equa­tions, and re­lated to­po­lo­gic­al prob­lems. she used Ahlfors's tech­nique of con­form­al map­ping to show that an en­tire func­tion of or­der p has at most 2p asymp­to­mat­ic val­ues. This be­came known as Cartwright's The­or­em, and is still fre­quently ap­plied in sig­nal pro­cessing.


AwardsShe was awar­ded a re­search fel­low­ship at Gir­ton Col­lege, Cam­bridge Uni­versity, to con­tin­ue her study of the the­ory of func­tion. She was also awarded De Morgan Medal.

CareerCartwright taught math­em­at­ics in Worcester and Buck­ing­ham­shire for the next four years be­fore re­turn­ing to Ox­ford for her D.Phil. in 1928. By 1935, she had been ap­poin­ted a Lec­turer in Math­em­at­ics at Cam­bridge.1959, when she would be­come a Read­er in the The­ory of Func­tions, the po­s­i­tion she would re­tain un­til her re­tire­ment. Cartwright re­tired from Gir­ton in 1969, but con­tin­ued to teach as a vis­it­ing pro­fess­or in Eng­land, Amer­ica and Po­land.She was ap­poin­ted Dame of the Brit­ish Em­pire the year after she left Gir­ton Col­lege. After years of teach­ing abroad, Cartwright re­turned to Cam­bridge, where she was one of the ed­it­ors of The Col­lec­ted Pa­pers of G. H. Hardy. She died there in 1998.

Fun FactsFor a time Cartwright ser­i­ously con­sidered giv­ing up math­em­at­ics al­to­geth­er and re­turn­ing to his­tory, since she when she re­ceived second-class hon­ors in­stead of the first-class award.She also made ground-break­ing con­tri­bu­tions to chaos the­ory.She also was apart of a team that discovered communation used in World War II

ChildhoodMary was home-schooled till she was 11. After she was sent to Leam­ing­ton High School. Her best subject at school was history but it had the disadvantage of much effort in learning endless lists of facts. Later, in her last year at the Godol­phin School in Salis­bury, Cartwright was en­cour­aged to study math­em­at­ics. 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.

EducationIn 1919, Cartwright be­came one of five wo­men study­ing math­em­at­ics at Ox­ford Uni­versity. This was a difficult time to enter university since, World War I having just ended, there were large numbers of men returning from the 1923 she gradu­ated from Ox­ford with a first-class de­gree from her Fi­nal Hon­ors.In 1930 she was awar­ded her D.Phil and her thesis. The end of Mary’s edu­ca­tion at Ox­ford began many years of re­search and teach­ing.
