Northwestern first fielded an intercollegiate football team in 1882, and later became a founding member of the Big Ten Conference. Northwestern became affiliated with professional schools of law, medicine, and dentistry throughout the Chicago area in the 1870s and 1880s. Enrollments grew through the 1890s, and under Henry Wade Rogers these new programs were integrated into a modern research university combining professional, graduate, and undergraduate programs, and emphasizing teaching along with research. The Association of American Universities invited Northwestern to become a member in 1917. Under Walter Dill Scott's presidency from 1920 to 1939, Northwestern began construction of an integrated campus in downtown Chicago designed by James Gamble Rogers to house the professional schools, the establishment of the Kellogg School of Management, as well as opening new buildings on the Evanston campus like Dyche Stadium and Deering Library. A proposal to merge Northwestern with the University of Chicago was considered in 1933, but rejected by Northwestern.
