In late 1883, Wilson entered Johns Hopkins University. Wilson's course of study included history, political science, German, and other areas. Wilson hoped to become a professor, writing that "a professorship was the only feasible place for me, the only place that would afford leisure for reading and for original work, the only strictly literary berth with an income attached." Wilson spent much of his time at Johns Hopkins writing "Congressional Government: A Study in American Politics", which grew out of a series of essays in which he examined the workings of the federal government. He received a Ph.D. in history of government from Johns Hopkins in 1886, making him the only U.S. president who possessed a doctorate degree. In early 1885, Houghton Mifflin published "Congressional Government", which received a strong reception; one critic called it "the best critical writing on the American constitution which has appeared since the "Federalist Papers"." That same year, Wilson accepted a teaching position at Bryn Mawr College, a newly established women's college on the Philadelphia Main Line. Wilson taught at Bryn Mawr College from 1885 until 1888. He taught ancient Greek and Roman history, American history, political science, and other subjects. In 1888, Wilson left Bryn Mawr for Wesleyan University in Middletown, Connecticut. At Wesleyan he coached the football team, founded a debate team, and taught graduate courses in political economy and Western history.
