What is the first co-ed college in the U.S?
The first coeducational college—one that accepts women as well as men—was Oberlin Collegiate Institute in Oberlin, Ohio. It opened on Dec. 3, 1833 with 44 students, including 29 men and 15 women. Fully equal status for women didn't come until 1837, and the first three women to graduate with bachelor's degrees did so in 1841.
Oberlin was also one of the first schools to admit blacks on equal footing with white students and it was even a stop on the Underground Railroad to Canada.
The school became Oberlin College in 1850, and today it comprises a College of Arts and Sciences, with about 2,400 students, and a Conservatory of Music, with about 500 enrolled.
