1886: Winifred Edgerton Merill
The first American Woman to receive a PhD. in math (from Columbia University) was Winifred Edgerton Merill who was born and raised in Ripon, WI. At the end of her second year she petitioned to receive a Ph.D. degree, having fulfilled the required credits and written an original thesis titled “Multiple Integrals” that dealt with geometric interpretations of multiple integrals and translations and relations of various systems of coordinates. Her work in mathematical astronomy included computation of the orbit of the comet of 1883. After some controversy, the board unanimously voted to award her the Ph.D. in mathematics, which she received in 1886 with highest honors.

The fourth person to receive a PhD in Math at UW was Florence Eliza Allen. She remained at the University of Wisconsin as an instructor in mathematics for the next thirty years, publishing two more papers on “A Certain Class of Transcendental Curves” and “Closure of the Tangential Process on the Rational Plane Cubic”. Allen was promoted to assistant professor in 1945, retiring with the title Assistant Professor Emeritus. (her PhD advisor was Van Vleck)
1930: Elizabeth Stafford Hirschfelder
Elizabeth Stafford Hirschfelder received a Math PhD (advisor Mark Ingraham) She later married Ivan Sokolnikoff (PhD 1931), who was on the faculty from 1927-1944. She taught until 1954. The title of Dr. Hirschfelder’s thesis was “Matrices conjugate to a given matrix with respect to its minimum equation.” She taught mathematics at Wisconsin for almost 20 years. With her first husband, Ivan Sokolnikoff, she co-authored in 1934 the important textbook “Higher Mathematics for Engineers and Physicists.” In 1997 she started the Elizabeth S. Hirschfelder Fund for Graduate Women in Mathematics, Chemistry, and Physics at the UW-Foundation.
1954: Etta Falconer

1959: Mary Ellen Rudin
Mary Ellen Rudin taught at UW starting in 1959 to 1991. She was promoted from Lecturer to Full Professor (in 1971). She served as vice-president of the American Mathematical Society, from 1980-1981. Rudin is best known in topology for her constructions of counterexamples to well-known conjectures. Most famously, she was the first to construct a ZFC Dowker space, thus disproving a conjecture of Dowker’s that had stood, and helped drive topological research, for more than twenty years. Her example fuelled the search for “small” ZFC Dowker spaces. She also proved the first Morita conjecture and a restricted version of the second. Her last major result was a proof of Nikiel’s conjecture.
