From the Elmer Colpitts papers:
“She attended normal school at Fredericton in 1890-91, and she and her brother Weldon, roomed and boarded at the same house. The school law for teaching in New Brunswick in 1891 required one school year's work at normal school and provided that a woman must be 16 years old before she could teach in the public schools, and that a man must be 18 years old to teach in the public schools. Julia was 16 years old February 22, 1891 and Weldon was 18 years old on May 4, 1891. Julia taught in New Brunswick schools from 1891 to 1895. She attended Mt. Allison from 1895 to 1899 and received her B.A. degree with honors in Mathematics. She was at Cornell University during the school years 1899-1900 and received her M.A. degree in 1900. She went to Iowa State College in the fall of 1900 and taught mathematics there the rest of her life except for a few leaves of absence. She did graduate work ata the University of Chicago for several summers and at Cornell University for a school year and received her Ph.D. degree in Mathematics from Cornell at the end of the school year (probably 1924). She spent quite a number of summer vacations with her mother. She and Miss Maria Roberts of Iowa State College were the authors of "Analytic Geometry" by Roberts and Colpitts. She died following an operation in a hospital in Southhampton, England as she was returning from a trip to Sweden. Her body was interred at Point de Bute, Westmorland County, New Brunswick, Canada.”95
