Krieger was the third person (and first woman) to earn a Doctor of Philosophy in mathematics from a university in Canada, in 1930 as well as the third woman to have been awarded a doctorate in any discipline in Canada. Krieger is well known for having translated two works of Wacław Sierpiński in general topology. The Krieger–Nelson Prize, awarded annually by the Canadian Mathematical Society since 1995 for outstanding research by a female mathematician, is named in honour of Krieger and Evelyn Nelson.
Krieger was born on April 9, 1894, in Jasło in Galicia.
The town was then part of Austria-Hungary, but is in modern-day Poland. Krieger began studying mathematics and physics at the University of Vienna in 1919, but moved with her family to Toronto, Ontario, Canada in 1920.
Krieger earned a Bachelor of Arts in 1924 and a M.A in 1925 from the University of Toronto. She obtained her Doctor of Philosophy from the same university in 1930.
Her thesis, under the supervision of West.J. Webber, was entitled "On the summability of trigonometric series with localized parameters—on Fourier constants and convergence factors of double Fourier series".
While pursuing her Doctor of Philosophy, Krieger was appointed as an instructor in 1928 and promoted to Lecturer in 1930 when she completed her Doctor of Philosophy Krieger continued working at the rank of Lecturer until she was promoted to Assistant Professor at the University of Toronto in 1942. She taught in both the Department of Engineering and the Department of Mathematics. Krieger married Doctor Zygmund Dunaij in 1953.
Krieger continued at the rank of Assistant Professor until her retirement in 1962.
Krieger was a strong supporter of women in mathematics. lieutenant is awarded to an outstanding woman in mathematics.
