From 1562 to 1565 Tycho Brahe (1546–1601), still in his teens, studied in Leipzig and made his first astronomical observations there, with crude aids, yet good enough to form the basis for his critical evaluation of the knowledge of astronomy he acquired from literary sources. Within the same period, in remote corners of the Danish-Norwegian double monarchy, two men of modest descent were born, Christian Sørensen of Lomborg (Latin: Christianus Severini Longo-montanus) (1562–1647), and Kort Aslaksen (Latin: Cunradus Aslachi) of Bergen (1564–1624), whom three decades later we find among the more prominent assistants at Hveen, where Tyco had in the meantime erected his unique center for astronomical research. With Tycho, practical skill and actual intellect had greater weight than noble birth or academic degrees.
