Mary Ellen Rudin (December 7, 1924 – March 18, 2013) was an American mathematician.[1]

Born Mary Ellen Estill, she attended the University of Texas, completing her B.A. in 1944 and her Ph.D. in 1949, under Robert Lee Moore.[2] During her time as an undergraduate, she was a member of the Phi Mu Women's Fraternity,[3] and was elected to the Phi Beta Kappa society.[4] In 1953, she married the mathematician Walter Rudin. Following her mentor Moore, her research centered on point-set topology. She was appointed as Professor of Mathematics at the University of Wisconsin in 1971, and after retirement served as a Professor Emerita there. She served as vice-president of the American Mathematical Society, 1980–1981. In 1984 she was selected to be a Noether Lecturer. She was an honorary member of the Hungarian Academy of Sciences (1995). In 2012 she became a fellow of the American Mathematical Society.[5]

Rudin is best known in topology for her constructions of counterexamples to well-known conjectures. Most famously, she was the first to construct a Dowker space, thus disproving a conjecture of Dowker's that had stood, and helped drive topological research, for more than twenty years. She also proved the first Morita conjecture and a restricted version of the second.[6] Her last major result was a proof of Nikiel's conjecture.[7] Rudin's Erdős number is 1.

"Reading the articles of Mary Ellen Rudin, studying them until there is no mystery takes hours and hours; but those hours are rewarded, the student obtains power to which few have access. They are not hard to read, they are just hard mathematics, that's all." (Steve Watson[8])

She resided in Madison, Wisconsin, in the Rudin House, a home designed by architect Frank Lloyd Wright.
