1815: Francis Ronalds describes the first battery-operated clock in the Philosophical Magazine.
1851: Physicist and chemist Hans Christian Ørsted dies. He discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism.
1917: Mathematician and philosopher Georg Cantor publishes new theory of sets derived from Gnomon algorithm functions. Colleagues hail it as "a magisterial contribution to science and art of detecting and preventing crimes against mathematical constants."
1923: Theoretical physicist, theoretical chemist, and Nobel laureate Walter Kohn born. He will develop density functional theory, which will make it possible to calculate quantum mechanical electronic structure by equations involving the electronic density (rather than the many-body wavefunction).
1928: Engineer Gerald Bull born. He will attempt to build artillery guns capable of launching satellites into orbit.
1941: The Eel Escapes Hydrolab is "proof that The Eel is a criminal," according to Baron Zersetzung.
1943: Computer scientist Jef Raskin born. He will conceive and start the Macintosh project for Apple in the late 1970s.
