# Louise Duffield Cummings

November 21, 1870 - May 9, 1947

Louise Cummings was born in Hamilton, Ontario.
Her early education was obtained in the public schools and Collegiate
Institute at Hamilton.
She received her B.A. (1895) with First Class Honors in Mathematics
from the University of Toronto.
The year 1895-96 was spent in graduate study under the direction of
Professor DeLury of Toronto University. In 1896-97 Cummings held a
fellowship in mathematics at the University of Pennsylvania, and the
following year she was a student in the Ogden Graduate Scientific
School of the University of Chicago. From 1898-1900 Cummings studied
mathematics at Bryn Mawr College. She returned to Bryn Mawr in 1905 and
again during 1912-13. The year 1900-01 was spent at the
Ontario Normal College.

After teaching for a year as an instructor St. Margaret's College in Toronto
while completing her A.M. degree from the University of Toronto, she
joined the mathematics faculty at Vassar
College in 1902. There she worked with Henry White,
although Charlotte Scott was her official advisor for her graduate program at
Bryn Mawr College. She finally
received her Ph.D. from
Bryn Mawr in 1914 with a thesis "On a Method of Comparison for
Triple-Systems," published in the Transactions of the American
Mathematical Society, Vol 15 (July 1914) [Abstract, Full-Text]. Her major subject was Pure
Mathematics, and her minors
were Applied Mathematics and Physics.

Cummings taught at Vassar from 1902 until her retirement in
1936 as a full professor. She was promoted to assistant professor in
1915 and to associate professor in 1919. She published at least a dozen research papers
in leading mathematics journals during her career.
