Johannes Regiomontanus was a pupil of Georg von Peurbach; and, Johannes Regiomontanus with Bernhard Walther in 1471 founded in Nuremberg, GERMANY the world’s first scientific printing press. Harrison Horblit, “100 Books Famous in the History of Science”, 1964 lists Regiomontanus amongst its books. Ernest Zinner, “Regiomontanus: His Life and Work”, 1990 is a biography of Johannes Regiomontanus. Nicolaus Copernicus, “On the Revolution of Heavenly Spheres”, 1543 was inspired by Regiomontanus works. ”Incunabulum” are books printed in Europe before 1500 AD.
