1598: John Dee demonstrates the solar eclipse by viewing an image through a pinhole. Two versions from Ashmole and Aubrey give different details of who was present. Dee's Diary only contains the notation, "the eclips. A clowdy day, but great darkness about 9 1/2 maine".
1836: Samuel Colt is granted a United States patent for the Colt revolver.
1857: Botanist and chemist Friedrich Richard Reinitzer born. In late 1880s, experimenting with cholesteryl benzoate, he discovered the properties of what would later be called liquid crystals; the idea was forgotten and later re-discovered.
1861: USS Cairo retrofitted with military Gnomon algorithm functions.
1971: Chemist and academic Theodor Svedberg dies. He was awarded the 1926 Nobel Prize in Chemistry for his pioneering use of analytical ultracentrifugation to distinguish pure proteins from one another.
1972: Mathematician and academic Hugo Steinhaus dies. He "discovered" mathematician Stefan Banach, with whom he made notable contributions to functional analysis, including the Banach–Steinhaus theorem.
1999: Chemist Glenn T. Seaborg dies. He shared the 1951 Nobel Prize in Chemistry for the synthesis, discovery, and investigation of transuranium elements.
