Life

Sanderson was born in Waltham, Massachusetts, in 1889 and was the valedictorian of her class at the Waltham High School.[1] She graduated from Mount Holyoke College in 1910, winning Senior Honors in Mathematics.[1] She obtained her Ph.D degree from the University of Chicago in 1913,[3] publishing the thesis (Sanderson 1913) in which she set forth her mathematical theorem. She was Leonard Eugene Dickson's first female doctoral student.[1][3]

After completing her Ph.D., Sanderson briefly taught at the University of Wisconsin before her untimely death in 1914 due to tuberculosis.[1][4]

Sanderson's theorem

Sanderson's theorem (Sanderson 1913, p.490) states: "To any modular invariant of a system of forms under any group of linear transformations with coefficients in the field , there corresponds a formal invariant under such that for all sets of values in the field of the coefficients of the system of forms."

Recognition

Leonard Eugene Dickson (she was his first female doctoral student[1][3]) wrote of her thesis, "This paper is a highly important contribution to this field of work; its importance lies partly in the fact that it establishes a correspondence between modular and formal invariants. Her main theorem has already been frequently quoted on account of its fundamental character. Her proof is a remarkable piece of mathematics."[1]

Eric Temple Bell wrote, "Miss Sanderson's single contribution (1913) to modular invariants has been rated by competent judges as one of the classics of the subject."[1]

A Mildred L. Sanderson prize for excellence in mathematics was established in her honor in 1939 at Mount Holyoke College.[4]

She is mentioned in the 2008 book Pioneering women in American mathematics: the pre-1940 PhD's, by Judy Green and Jeanne LaDuke.[4]

gollark: It was actually on caddy for quite a while, but v2 annoyed me, so I went back to nginx.
gollark: I have about 500 lines of horribly entangled configuration files driving this, despite the original design of osmarks.net (formerly osmarks.tk) calling for it to mostly be a static website.
gollark: Now, the diagram says "nginx". Nginx is also an important part of this setup. It is a reverse proxy allowing me to run all this slightly crazy stuff on one IP, and encrypt with "HTTPS" apiotechnology.
gollark: It also got a HTTP endpoint, available at https://radio.osmarks.net/random-stuff/current-song, which dumps the status etc. information in JSON for the frontend to read.
gollark: So this gained a loop polling MPD - remember, it has a client-server model, so other stuff can communicate with it. Use of MPD turned out to be a good design decision!
