title: History of Ohio State University
context: The Ohio State University was founded in 1870 as a land-grant university in accordance with the Morrill Act of 1862 under the name of Ohio Agricultural and Mechanical College.[1][2] The school was originally situated within a farming community located on the northern edge of Columbus, and was intended to matriculate students of various agricultural and mechanical disciplines. The university opened its doors to 24 students on September 18, 1873. In 1878, the first class of six men graduated. The first woman graduated the following year.[3] In 1900, in light of its expanded focus, the college permanently changed its name to the now-familiar "The Ohio State University". Ohio State began accepting graduate students in the 1880s, with the university awarding its first master's and doctoral degrees in 1886 and 1890 respectively.  1891 saw the founding of Ohio State's law school. Presently, the university has reached the ranking of becoming a Public Ivy, as well as receiving high rankings and awards from many institutions, including U.S. News, Academic Ranking of World Universities.
