E. H. Moore: Eliakim Hastings Moore was an American mathematician who helped develop abstract algebra and modern mathematical analysis. Moore supervised Wheeler's doctoral work at the University of Chicago.
Functional analysis: Functional analysis studies vector spaces with limits, especially spaces of functions, and the operators acting on them. Wheeler's research helped develop this field's early theory of operators and equations.
Women in mathematics: Women in mathematics are people whose mathematical work has developed the subject across its history and institutions. Wheeler's doctorate and professorship marked rare achievements for an American woman of her generation.
University of Chicago Department of Mathematics: The University of Chicago Department of Mathematics is an academic unit devoted to mathematical research and teaching. Wheeler studied and taught in the department during its formative years.
Ernest William Brown: Ernest William Brown was a British-American mathematician known for mathematical astronomy and lunar theory. Wheeler studied with Brown at Haverford College, where he taught.
Integral equation: An integral equation is an equation in which an unknown function appears inside an integral. Wheeler investigated how these equations could be solved through operator methods.
Women in science: Women in science are researchers and practitioners whose work spans scientific disciplines and historical periods. Her academic career belongs to the broader history of women's access to scientific professions.
Haverford College: Haverford College is a liberal arts college in Pennsylvania founded by the Religious Society of Friends. Wheeler earned her undergraduate degree there before pursuing graduate mathematics.
Leonard Eugene Dickson: Leonard Eugene Dickson was an American mathematician who worked in algebra and number theory. Dickson was among the University of Chicago mathematicians who shaped Wheeler's graduate education.
Linear operator: A linear operator is a map between vector spaces that preserves addition and scalar multiplication. Operators provide a framework for expressing and analyzing integral equations.
