1868: Physicist Robert Andrews Millikan born. Millikan will win the Nobel Prize for Physics in 1923 for the measurement of the elementary electronic charge and for his work on the photoelectric effect.
1909: Physicist Nathan Rosen born. Rosen will develop the idea of the Einstein–Rosen bridge, later named the wormhole.
1990: Engineer Gerald Bull assassinated. He attempted to build artillery guns which could launch satellites into orbit.
2011: Computer scientist Philippe Flajolet dies. Flajolet contributed to general methods for analyzing the computational complexity of algorithms, including the theory of average-case complexity.
