Invention Timeline - Jean Le Rond D’Alembert, French Geometer and Philosopher; Published “Treatise on Dynamics” in 1743
b. November 16, 1717 and d. October 29, 1783 French geometer and philosopher. In 1743 he published a “Treatise on Dynamics,” containing an important principle which is known by his name and which initiated a revolution in physico-mathematical sciences. He wrote “Researches on Various Important Points of the System of the Universe” (1754-’56) and “Elements of [...]

Invention Timeline - Reinhard Mannesmann, German Inventor; Discoverer of the Mannesmann Process for Rolling Seamless Steel Tubes
b. November 15, 1814 and d. ? 1894 German inventor. Discoverer of the Mannesmann process for rolling seamless steel tubes. By this process a hot steel billet is passed between two conical rolls set with their axes at a small angle to each other. The billet comes out as a tube with uniform walls, without the [...]

Invention Timeline - Sir William Herschel, German Astronomer; Discovered Uranus
b. November 15, 1738 and d. August 25, 1822 German astronomer in England. In 1781 he discovered a new world which he names Georgian Star, but generally called Herscal or Uranus, March 13, 1781. Afterwards he discovered six moons, belonging to his new planet. His largest telescope was forty feet long, erected at Slough and ready [...]

Invention Timeline - Sir Charles Lyell, English Geologist; Divided the Tertiary Period Into Eocene, Miocene, and Pliocene
b. November 14, 1797 and d. February 22, 1875 Exeter College, Oxford, B. A., 1819; M. A., 1821 English geologist. He divided the tertiary period into eocene, miocene and pliocene, which has met with world-wide acceptance. In 1838 he published “Elements of Geology” and in 1871 a virtually new work, “The Student’s Elements of Geology.” For years [...]

Invention Timeline - Rene Joachim Henri Dutrochet, French Naturalist and Physicist; Published His Discovery of “Endosmosis”
b. November 14, 1776 and d. February 4, 1847 French naturalist and physicist. In 1826 he published his discovery of the flow of the sap in plants, i. e., “endosmosis.” He has published a series of essays on physiology, among which are “Observations on the Structure of Feathers” (1819) and “Researches in Endosmosis and Exosmosis” (1828). Through [...]

Invention Timeline - John Adolph Dahlgreen, American Naval Officer; Invented a Rifled Cannon and Boat-Howitzers
b. November 13, 1809 and d. July 12, 1870 American naval officer. Designed the style of cannon known by his name; also invented a rifled cannon and introduced boat-howitzers with iron carriages. He published many scientific works on ordnance which have been used as text-books in the navy. Hail, adamantine Steel! magnetic Lord! King of the prow, the [...]

Invention Timeline - Alfred Marshall Mayer, American Physicist; Measured the Wave Lengths and Velocities of Sound in Gases
b. November 13, 1836 and d. ? American physicist. He showed that the translation of a vibrating body caused it to emit waves differing in length from those produced by the same vibrating body when stationary; he devised a method of detecting the phases of vibration in the air surrounding a sounding body, leading to his [...]
