Yael Dowker

Yael Naim (later Dowker) was born in Tel Aviv. Dowker did her doctorate at Radcliffe College (in Cambridge, Massachusetts) under Witold Hurewicz (a Polish mathematician known for the Hurewicz theorem). She published her thesis Invariant measure and the ergodic theorems in 1947 and received her Ph.D. in 1948. In the period between 1948 and 1949, she did post-doctoral work at the Institute for Advanced Study, located in Princeton, New Jersey. A few years after the war, McCarthyism became a common phenomenon in the academic world, with several of the Dowker couple's friends in the mathematical community harassed and one arrested. In 1950, they emigrated to the United Kingdom. and later went to the Imperial College London, where she was the first female reader within the department. While there, among the students she advised was Bill Parry, who published his thesis in 1960. She also cooperated on some of her work with the Hungarian mathematician Paul Erdős (Erdős' number of one). She worked with her husband with gifted children who were having difficulties at school for the National association for gifted children. == Legacy ==

The best PhD award at Imperial College London is given in her name each year. ==Works==
