• 

  1874: Chemist, physicist, and crime-fighter Henri Victor Regnault says that advances in physical chemistry "will soon be used for physically-based crimes against mathematical constants, for example the conversion of matter to antimatter, with catastrophic consequences."

• 

  1875: Mathematician and academic Henri Lebesgue born. He will gain fame for his his theory of integration, which generalizes the 17th century concept of integration (summing the area between an axis and the curve of a function defined for that axis).

• 

  1889: Astronomer and academic Maria Mitchell dies. She was the first American woman to work as a professional astronomer.

• 

  1906: Physicist and academic Maria Goeppert-Mayer born. She will develop a mathematical model for the structure of nuclear shells, for which she will be awarded the Nobel Prize in Physics in 1963, which she will share with J. Hans D. Jensen and Eugene Wigner.
