Emmy Noether

1882 – 1935

by Lane Saunders Mac

Emmy Noether, a German mathematician, was the world leader in the twentieth-century development of modern “abstract” algebra. Her writing, the students she inspired, and their books wholly changed the form and content of higher algebra throughout the world.

Noether was born in Erlangen, Germany, on March 23, 1882. Her father, Max Noether, was a professor of mathematics at Erlangen, an expert on algebraic geometry. She received her Ph.D. in mathematics from Erlangen in 1907, with a dissertation on invariant theory (involving what she later would call “computational” algebra). In 1915, she moved to Göttingen, as an assistant to the world-famous mathematician David Hilbert. There, she gave a course in his name (she was not allowed to lecture at the time on her own account) and applied her knowledge of invariant theory to relativity theory in a paper that impressed Einstein.

In 1920, she turned her attention to algebra, with decisive axiomatic treatment of the theory of ideals as they apply to number theory (to factor algebraic integers) and to algebraic geometry (curves and surfaces defined by equations). She inspired many students, in particular the Dutchman B.L. Van der Waerden, who delivered brilliant lectures following her ideas and then presented them in his famous text Modern Algebra, which revolutionized the subject. As a graduate student in Göttingen (1931–1933), I attended her lectures and learned something of her insights. Subsequently, in 1941, Garrett Birkhoff and I published an undergraduate text, Survey of Modern Algebra, which introduced the Noether view of mathematics to English-speaking students. Noether’s lectures also influenced many young French mathematicians, several of whom (André Weil, Claude Chevalley) went on to found the Bourbaki group, whose systematic treatise on all of mathematics was much influenced by Noether’s methods. She was also active in algebraic topology, a field in which she persuaded the experts (Paul Alexandroff and Heinz Hopf) to describe topological invariants not as “numbers,” but instead as algebraic objects (groups). Her own research (with Brauer and Hasse) in 1930 solved a famous problem in the theory of algebras. Her brother was also a mathematician, but Emmy Noether was so well known that she was called “der Noether.”

With the rise of Hitler in 1933, Emmy Noether was dismissed from her modest position as Ausserordentliche Professor at Göttingen—she was not only Jewish but a woman and a liberal. The Rockefeller Foundation helped to fund a position for her in the United States at Bryn Mawr College, where there was a long tradition of interest in higher mathematical research. There she was also able to travel once a week to Princeton University, to lecture there and at the Institute for Advanced Study, giving her effective access to one of the great centers of American mathematics. At Bryn Mawr, she helped various young women mathematicians. She advised Marie J. Weiss and guided the Ph.D. thesis of Ruth Stauffer (McKee). She also helped olga taussky-todd, whom she had known in Göttingen.

Emmy Noether died on April 14, 1935, from complications following surgery. Her ideas about the abstract and conceptual approach of mathematics have been spread throughout the mathematics world by her students, her admirers, and many others who had personal contact with her. In the judgment of many, she is the greatest algebraist of the twentieth century.

The "mother" of twentieth-century mathematics, Emmy Noether spearheaded the development of modern abstract algebra. Her ideas revolutionized current understanding of algebra and laid the groundwork for further work by her "children" and "grandchildren" in the mathematical world, who consider her the greatest algebraist of the last hundred years.
