Where is the Alma mater of most US presidents?

Nine Presidents never attended college: Washington, Jackson, Van Buren, Taylor, Fillmore, Lincoln, A. Johnson, Cleveland, and Truman. The college that has the most presidents as alumni (six in total) is Harvard: J. Adams, J. Q. Adams, T. Roosevelt, F. Roosevelt, Kennedy, and G. W. Bush (business school). Yale is a close second, with five presidents as alumni: Taft, Ford (law school), G.H.W. Bush, Clinton (law school), and G. W. Bush.
