Kuiper's alma mater was Leiden University (of the Leiden Jar fame), where he was associated with Ejnar Hertzsprung, Jan Oort and Paul Ehrenfest, amongst others. He obtained a BSc. in Astronomy, and a Ph.D. in 1933 on binary stars, after which he went to the Harvard College Observatory in 1935, and then the Chicago University Yerkes Observatory in 1937.

Kuiper's impact on astronomy, particularly studies of the solar system, is reflected in the frequent use of his name for craters, an observatory, a planetoid, and the Kuiper Belt, although he did not discover it himself.

Stephen Hawking

b. 1942

Stephen Hawing is possibly the most-recognisable living scientist. His work in cosmology is considered the most advanced in explaining phenomena such as black holes, and unites general relativity with quantum mechanics.
