## Biography

Born in Easton, Pennsylvania, Susan Rambo was the eldest child of George and Annie Rambo. Her father was a wholesale grocer. She graduated high school in Easton, then entered Smith College, located in Northampton, Massachusetts. After graduating from Smith, she taught high school mathematics in Hoosick Falls, New York until 1908.

Susan Rambo joined the mathematics department at her alma mater in 1908 as an assistant in mathematics and remained there the remainder of her career with promotions to instructor in 1911, assistant professor in 1918, associate professor in 1922 and professor in 1937. She was department chairman from 1934 to 1940 and retired in 1948 as professor emeritus. One of her students was Mabel Gweneth Humphreys.

Her thesis was “A comparative study of analytic and synthetic projective geometry”. In 1916 she took a leave of absence from Smith and studied for her PhD the next two years at the University of Michigan. Her dissertation, “The point at infinity as a regular point of certain linear difference equations of the second order” was directed by Walter Burton Ford.
