Purdue University, located in West Lafayette, Indiana, U.S., is the flagship university of the six-campus Purdue University System. Purdue was founded on May 6, 1869, as a land-grant university when the Indiana General Assembly, taking advantage of the Morrill Act, accepted a donation of land and money from Lafayette businessman John Purdue to establish a college of science, technology, and agriculture in his name. The first classes were held on September 16, 1874, with three buildings, six instructors, and 39 students. Today, Purdue enrolls the second largest student body of any university in Indiana as well as the second largest international student population of any public university in the United States. Overall, Purdue is ranked 18th among U.S. public universities, and 56th among all U.S. universities, according to U.S. News and World Report. Purdue offers both undergraduate and graduate programs in over 210 major areas of study. Purdue has produced multiple Nobel Prize winners, Fortune 500 executives, Super Bowl MVPs, Grammy Award nominees, and Pulitzer Prize winners, and the university's alumni pool collectively holds over 15,000 United States patents.
