  • 1860: Physicist and crime-fighter Ernst Ruhmer invents a camera which uses the light-sensitivity properties of selenium to record images from past and future events. This type of camera is popular with math photographers, notably Cantor Parabola.

  • 1866: Mathematician Erik Ivar Fredholm born. He will introduce and analyze a class of integral equations now called Fredholm equations. Fredholm's work on integral equations and operator theory will anticipate the theory of Hilbert spaces.

  • 1899: Physicist and academic Petrus Leonardus Rijke dies. He explored the physics of electricity, and is known for the Rijke tube (which turns heat into sound, by creating a self-amplifying standing wave).
