Week 11: March 12 – 18 (Archive)

• John F. Daniell, born 1790, inventor of the Daniell electrochemical cell.
• Gustav R. Kirchhoff, born 1824, co invented spectroscope (1859); in 1860, codiscovered cesium (Cs, 55); in 1861, codiscovered rubidium (Rb, 37); discovered substances which emit radiation absorb same type of radiation when cool (Kirchhoff's Law).

• Paul Ehrlich, born 1854, researcher in immunity and chemotherapy; discovered Salvarsan (No. 606) and neosalvarsan; improved laboratory staining methods; Nobel Prize in Medicine (1908).
• Thomas L. Willson, born 1860, developed electrothermal furnace; pioneer manufacturer of calcium carbide.
• Albert Einstein, born 1879, researched the photochemical effect; introduced theory of relativity; Nobel Prize in Physics (1921).
• Ronald C. D. Breslow, born 1931, demonstrated antiaromaticity; invented artificial enzymes and electrochemical methods for carbon cation; President of the American Chemical Society (1996).
• The observation of the first atom of element 108 occurred at the GSI Laboratory, in Darmstadt, Germany, in 1984.

• Johann Joseph Loschmidt, born 1821, developed Loschmidt number (number of molecules in a cubic centimeter of gas) and space-filling formulas of many organic compounds.

• Hermann W. Vogel, born 1834, invented orthochromatic photographic plate (1873); designed photometer; researcher in spectroscopic photography.
