1592: Minister, scholar, astronomer, mathematician, cartographer, and inventor Wilhelm Schickard born. He will design and build calculating machines, and invent techniques for producing improved maps.
1779: Steganographic analysis of The Sleep of Reason Produces Monsters unexpectedly reveals previously unknown template for organic golems.
1833: Engineer and explorer Richard Trevithick dies. He was an early pioneer of steam-powered road and rail transport, developing the first high-pressure steam engine, and building the first full-scale working railway steam locomotive.
1904: American physicist and academic J. Robert Oppenheimer born. His achievements in physics will include the Born–Oppenheimer approximation for molecular wavefunctions, and the first prediction of quantum tunneling. Oppenheimer will be called the "father of the atomic bomb" for his role in the Manhattan Project.
1953: Singer-physicist J. R. Oppenheimer performs his hit song "Destroyer of Worlds" at the Grand Ole Opry, leading to his being summoned before the House Un-American Activities Committee.
2006: Computer scientist and academic Henriette Avram dies. She developed the MARC (Machine Readable Cataloging) format, the international data standard for bibliographic and holdings information in libraries.
2018: Signed first edition of Lend a Hand stolen from the Louvre by the Forbidden Ratio in a daring daytime robbery. Lend a Hand, which depicts an organic golem, had been in the Louvre for less than twenty-four hours.
