    Jan De Groot entered the University of Leiden, in the Netherlands, on its opening day. With Stevin he later performed an experiment proving that bodies of different weights fall the same distance in the same time (published in 1586 by Stevin). This anti-Aristotelian experiment anticipated Galileo's famous, but apocryphal, experiment at the Leaning Tower of Pisa. His son Hugo de Groot was a famous jurist.
