Mary Ellen Rudin was a famous American mathematician. She was born in Hillsboro, Texas, on December 7, 1924. Her family moved often because of her father's job as a civil engineer. Her mother, Irene, was an English teacher. Mary Ellen grew up around Leakey, Texas, with her younger brother. Her family valued learning very much. Her grandmothers both went to Mary Sharp College in Tennessee. This background helped her pursue a big career in math.

She was an expert in a field called set-theoretic topology. Topology is the study of shapes and spaces. Mary Ellen was famous for finding counterexamples. A counterexample is a special case that shows a math rule is wrong. In 1958, she found an unshellable triangulation of a tetrahedron. In 1971, she found a Dowker space. This discovery proved a rule by Clifford Hugh Dowker was wrong. Her work helped math researchers for many years.

Mary Ellen studied hard at the University of Texas. She finished her degree in 1944 after only three years. She later earned her Ph.D. in 1949. She worked under a mathematician named Robert Lee Moore. During college, she was in the Phi Mu Women's Fraternity. She was also part of the Phi Beta Kappa society. She later married another mathematician named Walter Rudin. They met while she was teaching at Duke University.

She taught at many important places. She taught at Duke University and the University of Rochester. In 1959, she became a lecturer at the University of Wisconsin. She became a Professor of Mathematics there in 1971. She was a speaker at the International Congress of Mathematicians in 1974. She also served as vice-president of the American Mathematical Society. In 1984, she was a Noether Lecturer. She lived in a house designed by Frank Lloyd Wright.

Many people honor her work today. In 2013, a group called Elsevier started a special prize. It is called the Mary Ellen Rudin Young Researcher Award. The prize gives $15,000 to young researchers in topology. They can use the money for conferences or research centers. The first prize was given to Logan C. Hoehn. This award helps new scientists follow in her footsteps. Her legacy lives on through these young thinkers.
