Ida May Schottenfels (December 21, 1869 – March 11, 1942) was an American mathematician and university professor.

Education and career

She was a student at the University of Chicago, earning a master's degree in mathematics in 1896.^[1] In 1910, she was appointed as head of the mathematics department at the University of Toledo. She was cited as one of the most "active" women mathematicians of the time.^[2] From 1891 to 1906 she gave 17 lectures at meetings of the American Mathematical Society and published three papers. She presented her paper "On a set of generators for certain substitution and Galois field groups" at the 1904 AMS meeting.^[1]

Research

In group theory, Schottenfels was the first mathematician to prove that there exist two non-isomorphic simple groups of the same order, by demonstrating that there are two non-isomorphic simple groups of order 20,160.^[3]
