On February 23, 1870, what was then known as State Agricultural College (now Michigan State University) opened its doors to 10 female students. These women, ranging in age from 16 to 23 – studied subjects including chemistry, botany, horticulture, floriculture, trigonometry, surveying, and entomology. No special courses for women were offered at that time, so they took the same classes as men and participated in the daily fieldwork alongside male students.
