Louise Duffield Cummings

Louise Duffield Cummings (21 November 1870 – 9 May 1947) was a Canadian-born American mathematician.

Education and career

Cummings received her B.A. in 1895 from the University of Toronto. She studied mathematics at the graduate level in 1895–1896 at the University of Toronto, in 1896–1897 at the University of Pennsylvania, in 1897–1898 at the University of Chicago, and in 1898–1900 at Bryn Mawr College. During 1900–1901 she taught at the Ontario Normal College and, while completing her A.M. at the University of Toronto, she taught at St. Margaret's College during 1901–1902.^[2]

Cummings joined the faculty of Vassar in 1902 as an instructor and was promoted to assistant professor in 1915, to associate professor in 1919, and to full professor in 1927^[3] before her retirement in 1936.^[2] She was an invited speaker at the International Congress of Mathematicians in 1924 at Toronto and again in 1932 at Zürich.
