Purdue University's School of Aeronautics and Astronautics prepares graduates to be exceptional, recognized contributors to aeronautical and astronautical engineering in industry, government laboratories, and universities. Purdue University has graduated 23 astronauts, more than any other public institution, and 13 of those hold degrees from the School of Aeronautics and Astronautics, including Neil Armstrong, the first man to walk on the Moon. Aeronautical education has existed on at least a small scale at Purdue University since about 1920. The School of Aeronautics was established as a separate entity on July 1, 1945.
