Edmond Halley left Oxford without an undergraduate degree to travel the world, giving him the opportunity to study astronomy on the spot. Upon returning to England he had a prestigious career and collaborated with Sir Isaac Newton, entered the public service, served as a professor at Oxford, and was appointed Astronomer Royal in 1721
