CHEMISTS Amadeo Avogadro, an Italian scientist, was born in 1776 and died in 1856, whlle he was professor of Physics in Turin He enun ciated the law that bears his name and thus laid the foundation for determining the number of atoms in a molecule of an elementary gas Avogadro showed the relation between the law of Gay Lussac and the atomic hypothesis of Dalton He assumed that the molecule of an elementary gas could be composed of smaller units, and that the relative densities of gases agree with the values determined by experiment Ernest Solvay C1839 19227 was born in Belgium He made prec tical a process for obtaining the carbonates of sodium directly from common salt by a precipitation method His scientific achiex ments brought him many honors and great wealth which he used gen erously in phllanthrooic and educational work He was promlnentln the political life of his country and was a member of the Belgian Senate Edward G Acheson, is the inventor of many important processes associated with the graphite and carbon compounds He is famous chiefly as the dlscoverer of carborundum, artificial graphite, and deflocculated graphite In connection with these industries he h s had a great deal to do with the development of electric furnaces He invented graphltized anodes, which are much more durable than carbon electrodes in electrolytic furnaces To meet the need for a highly refractory material he invented siloxlcon, a compound of temperatures He was awarded the Perkins Medal of the Society of Chemical Industry in January, l9lO Sir William Ramsay fl852 19167 was born in Glasgow, Scotland He was known as a remarkably, skillful experimenter He shared with Rayleigh the honor of the discovery of argon This element, although present in the atmosphere to the extent of almost one per cent, had escaped detection because of its chemical inactivity Further works by Ramsay indicated the presence of other previously undiscovered gases in small amounts, in the atmosphere, and showed that helium, formerly known only as a constituent of the sun, was given off by certain minerals With Soddy, he found that hellum lS one of the discomposition products oi radium Ramsay was awarded the Nobel Prize in 190A Robert W Bunsen 11811 18997 was born in Gottingen and edu cated in its university He was professor in several German Un1 versities At Heidelberg he had a career of nearly fifty years as a great teacher and brllliant investigator His researches led to the acceptance of the idea of radicals existing in com ounds Many of his simple and efficient laboratory devices, are in use today, notably the Bunsen burner Bunsen may be regarded as the founder of modern gas analysis His greatest vork was the invention, with Klrchhoff, of the spectroscope This instrument is useful in the detection of known elements, and has led to the discovery of new ones By its means Bunsen found calclum and rabidium ' ll I 1 . 1 .
