 Digital Archive Japan / DAJ, Joseph Louis Gay-Lussac, French chemist and physicist, c1860. Gay-Lussac (1778-1850) investigated the behaviour of gases and developed techniques of chemical analysis. He was important in industrial chemistry for the introduction of lead chambers for the production of sulphuric acid. Gay-Lussac made balloon ascents to investigate terrestrial magnetism and composition and characteristics of the atmosphere at different altitudes. He determined that the same volume of any gas will expand equally in response to the same increase in temperature. From Chemistry by James Sheridan Muspratt. (London, c1860). |
 Digital Archive Japan / DAJ, Leonhard Euler, 18th century Swiss mathematician, 1874. Euler (1707-1783) was one of the founders of pure mathematics. He made many decisive and formative contributions to every aspect of pure and applied mathematics, physics and astronomy and he introduced many new functions including the gamma function and elliptic integrals. He developed the theory of trigonometric and logarithmic functions, reduced analytical operations to more simplistic forms and introduced many notations that are still used today in mathematics. |
 Digital Archive Japan / DAJ, Gustav Robert Kirchhoff, German physicist, 1876. Kirchhoff (1824-1887) is known for his work on electricity, heat and optics. His collaboration with Robert Wilhelm Bunsen (1811-1899) on spectrum analysis led, in 1859, to the discovery of caesium and rubidium. He also formulated two laws governing electric networks. From Discoveries and Inventions of the 19th Century by Robert Routledge. (London, 1876). |
