In Brief

A self-proclaimed torchbearer for matrix theory, Olga Taussky-Todd made the previously little-known field essential for scientists and mathematicians. After earning a PhD in algebraic number theory in Vienna, Taussky-Todd took various academic positions around Europe. She turned her interests to matrix theory while working on aircraft design at the National Physical Laboratory in London during the war years. Taussky-Todd immigrated to America in 1947, living first in Washington, D.C., and then moving to California to work and teach at CalTech. Olga Taussky-Todd published roughly 200 papers in her lifetime, was acclaimed the LA Times’ 1963 Woman of the Year, served on the councils of both the London and American Mathematical Societies, and was honored with the Austrian Cross of Science and Art.

Olga Taussky-Todd called herself a “torchbearer for matrix theory.” Her subject originated in the mid-nineteenth century, remaining a province of mathematicians until physicists reinvented it in the 1920s to interpret quantum mechanics. Her work and passion helped shape matrix theory and draw other talented mathematicians to its development. A century after its inception, matrix theory joined calculus as an essential component of a scientist’s education.

Early life and work: Austria and England

She was born on August 30, 1906, in Olümz, Austro-Hungary (later Olomouc, Czechoslovakia). She came from a well-to-do, cultivated Jewish family, the second of three daughters of Julius David and Ida (Pollach) Taussky. In 1909, the family settled in Linz, where her father worked as an industrial chemist and journalist. All three sisters pursued scientific careers. Olga entered the University of Vienna in 1925 to study mathematics and chemistry, but after a year left chemistry to study the philosophy of mathematics. It was the time of Moritz Schlick’s famous Vienna Circle, which attracted philosophers and scientists from around the world. Kurt Gödel, whose work at age twenty-five shook the foundations of mathematics, became her mentor and friend.

When Olga finished her dissertation on algebraic number theory in 1930 with Philip Fürtwangler, Richard Courant brought her to the world renowned Göttingen Mathematics Institute for a one-year appointment to edit Hilbert’s manuscript on number theory. There she met Emmy Noether, the preeminent woman mathematician of the century, and Princeton geometer Oswald Veblen. Courant, who in 1932 cautioned Olga about the volatile political situation in Germany, left Göttingen two years later for New York University, where he was to found a major mathematics institute. When Noether found refuge at Bryn Mawr, she and Veblen arranged a fellowship for Olga during 1934 and 1935.

Two lonely but productive years in Vienna followed, during which she supported herself by tutoring and an assistant’s stipend from Hans Hahn and Karl Menger. She spent the next two years at Girton College, Cambridge, England, and then, with mathematician G.H. Hardy’s help, she found a junior post at a women’s college in London University. In 1938, she married the Irish mathematician John Todd.

During World War II, Taussky-Todd worked on aircraft design at the National Physical Laboratory near London. This work turned her away from her first love, number theory, to her second, matrix theory.

Immigration to America

In 1947, her husband received a year’s appointment at the National Bureau of Standards in Washington. The matrix theorists assembled there and stirrings of the embryonic computer revolution made the offer appealing. Both were hired, traveling to America on a Liberty ship with a hundred war brides. They remained until 1957, when they were lured to the California Institute of Technology, Todd to be a professor of mathematics, and Taussky-Todd to be a research associate. She received tenure in 1963, but had to wait until 1971 for a professorial appointment, well after she had become internationally known. She published two hundred papers in her lifetime, most during her fertile thirty-eight years at Cal Tech, where she guided fourteen doctoral students.

Taussky-Todd’s Legacy

Among her many honors and awards were the Los Angeles Times Woman of the Year (1963) and the Mathematical Association of America’s Ford Prize (1970). She served on the councils of both the London and the American Mathematical Societies, and was vice president of the latter in 1986–1987. Both the journals Linear Algebra and its Applications and Linear and Multilinear Algebra published issues dedicated to her.

Taussky-Todd was visiting professor at the University of Vienna in 1965, accepted the Austrian government’s Cross of Honor in Science and Art in 1980, and later became a corresponding member of the Austrian and the Bavarian Academy of Sciences. Historians and others puzzle over the warm feelings some Austrian Jews, Taussky-Todd among them, retained for their country of origin in the face of Austria’s long tradition of virulent antisemitism. Her writings ascribe her career difficulties to academe’s prejudice against women, not to antisemitism. Though of Jewish birth, she identified herself with an international intellectual community, not a specifically Jewish one.

Olga Taussky-Todd died on October 7, 1995, in Pasadena, California, survived by her husband of fifty-seven years.
