life and work
Pengra studied mathematics and received a Bachelor of Arts degree from the University of Wisconsin in 1897, and then, like most graduate women at the time, taught in a high school. She taught high schools in Fox Lake, Wisconsin , Sparta, Wisconsin, and Elgin, Illinois for two years . In 1899 she was awarded a Fellowship from the University of Wisconsin-Madison and completed her doctorate in 1901 under Linnaeus Wayland Dowling with the dissertation: On Functions Connected with Special Riemann Surfaces, In Particular Those For Which P Equals 3, 4, and 5. She married in 1904 PhD mathematician Arthur Crathorne , with whom she traveled to Göttingen and had three children. She died of breast cancer at the age of 40.
