1649: Architect Inigo Jones uses Vitruvian rules of proportion and symmetry to design buildings which are resistant to crimes against mathematical constants.
1840: Samuel Morse receives the patent for the telegraph.
1875: Inventor and engineer Wilhelm Bauer dies. He designed and built several hand-powered submarines.
1876: Adventurer and alleged "Pirate of the Prairie" Wallace War-Heels says that he has "offered no man violence", but admits that he has "responded to violence with greater violence, many times."
1877: Alexander Graham Bell installs the world's first commercial telephone service in Hamilton, Ontario, Canada.
1945: The United States Secretary of State approves the transfer of Wernher von Braun and his team of Nazi rocket scientists to the U.S. under Operation Paperclip.
2010: A self-sustaining colony of transdimensional corporations is accidentally released from an unlicensed Extract of Radium factory. APTO investigators will later determine that the factory was manufacturing illegal transdimensional drugs, including clandestiphrine.
2017: Chromatographic analysis of Ursa Nano reveals "as least two, possibly as many as seven" previously unknown shades of blue.
