5 Schickhard(t), Wilhelm
SUBJECT AREA: Electronics and information technology[br]b. 22 April 1592 Herrenberg, Stuttgart, Germanyd. 24 October 1635 Tübingen, Germany[br]German polymath who described, and apparently built, a calculating "clock", possibly the first mechanical adding-machine.[br]At an early age Schickhard won a scholarship to the monastery school at Tübingen and then progressed to the university, where he obtained his BA and MA in theology in 1609 and 1611, respectively. He then specialized in oriental languages and eventually became Professor of Hebrew, Oriental Languages, Mathematics, Astronomy and Geography at Tübingen. Between 1613 and 1619 he was also deacon or pastor to a number of churches in the area. In 1617 he met Johannes Kepler, who, impressed by his ability, asked him to draw up tables of figures for his Harmonica Mundi (1619). As a result of this, Schickhard designed and constructed a mechanical adding-machine that he called a calculating clock. This he described in a letter of 20 September 1623 to Kepler, but a subsequent letter of 25 February 1624 reported its destruction by fire. After his death, probably from bubonic plague, his papers and the letter to Kepler were discovered in the regional library in Stuttgart in 1930 by Franz Hamme, who described them to the 1957 Mathematical Congress. As a result, a Dr Baron von Freytag Lovinghoff, who was present at that meeting, built a reconstruction of Schickard's machine in 1960.[br]Further ReadingF.Hamme, 1958, "Nicht Pascal sondern der Tübingen Prof. Wilhelm Schickhard erfund die Rechenmaschin", Buromarkt 20:1,023 (describes the papers and letter to Kepler).B.von F.Lovinghoff, 1964, "Die erste Rechenmaschin: Tübingen 1623", Humanismus undTechnik 9:45.——1973, "Wilhelm Schickhard und seine Rechenmaschin von 1625", in M.Graef (ed.), 350 Jahre Rechenmaschin.M.R.Williams, 1985, History of Computing Technology, London: Prentice-Hall.See also: Pascal, BlaiseKF -

9 Braun, Karl Ferdinand
[br]b. 6 June 1850 Fulda, Hesse, Germanyd. 20 April 1918 New York City, New York, USA[br]German physicist who shared with Marconi the 1909 Nobel Prize for Physics for developments in wireless telegraphy; inventor of the cathode ray oscilloscope.[br]After obtaining degrees from the universities of Marburg and Berlin (PhD) and spending a short time as Headmaster of the Thomas School in Berlin, Braun successively held professorships in theoretical physics at the universities of Marburg (1876), Strasbourg (1880) and Karlsruhe (1883) before becoming Professor of Experimental Physics at Tübingen in 1885 and Director and Professor of Physics at Strasbourg in 1895.During this time he devised experimental apparatus to determine the dielectric constant of rock salt and developed the Braun high-tension electrometer. He also discovered that certain mineral sulphide crystals would only conduct electricity in one direction, a rectification effect that made it possible to detect and demodulate radio signals in a more reliable manner than was possible with the coherer. Primarily, however, he was concerned with improving Marconi's radio transmitter to increase its broadcasting range. By using a transmitter circuit comprising a capacitor and a spark-gap, coupled to an aerial without a spark-gap, he was able to obtain much greater oscillatory currents in the latter, and by tuning the transmitter so that the oscillations occupied only a narrow frequency band he reduced the interference with other transmitters. Other achievements include the development of a directional aerial and the first practical wavemeter, and the measurement in Strasbourg of the strength of radio waves received from the Eiffel Tower transmitter in Paris. For all this work he subsequently shared with Marconi the 1909 Nobel Prize for Physics.Around 1895 he carried out experiments using a torsion balance in order to measure the universal gravitational constant, g, but the work for which he is probably best known is the addition of deflecting plates and a fluorescent screen to the Crooke's tube in 1897 in order to study the characteristics of high-frequency currents. The oscilloscope, as it was called, was not only the basis of a now widely used and highly versatile test instrument but was the forerunner of the cathode ray tube, or CRT, used for the display of radar and television images.At the beginning of the First World War, while in New York to testify in a patent suit, he was trapped by the entry of the USA into the war and remained in Brooklyn with his son until his death.[br]Principal Honours and DistinctionsNobel Prize for Physics (jointly with Marconi) 1909.Bibliography1874, "Assymetrical conduction of certain metal sulphides", Pogg.

10 Messel, Rudolf
SUBJECT AREA: Chemical technology[br]b. 14 January 1848 Darmstadt, Germanyd. 18 April 1920 London, England[br]German industrial chemist.[br]Messel served three years as an apprentice to the chemical manufacturers E.Lucius of Frankfurt before studying chemistry at Zürich, Heidelberg and Tübingen. In 1870 he travelled to England to assist the distinguished chemist Sir Henry Roscoe, but was soon recalled to Germany on the outbreak of the Franco-Prussian War. After hostilities ceased, Messel returned to London to join the firm of manufacturers of sulphuric acid Dunn, Squire \& Company of Stratford, London. The firm amalgamated with Spencer Chapman, and after Messel became its Managing Director in 1878 it was known as Spencer, Chapman \& Messel Ltd.Messel's principal contribution to chemical technology was the invention of the contact process for the manufacture of sulphuric acid. Earlier processes for making this essential product, now needed in ever-increasing quantities by the new processes for making dyestuffs, fertilizers and explosives, were based on the oxidation of sulphur dioxide by oxides of nitrogen, developed by Joshua Ward and John Roebuck. Attempts to oxidize the dioxide to the trioxide with the oxygen in the air in the presence of a suitable catalyst had so far failed because the catalyst had become "poisoned" and ineffective; Messel avoided this by using highly purified gases. The contact process produced a concentrated form of sulphuric acid called oleum. Until the outbreak of the First World War, Messel's firm was the principal manufacturer, but then the demand rose sharply, so that other firms had to engage in its manufacture. Production thereby increased from 20,000 to 450,000 tons per year.[br]Principal Honours and DistinctionsFRS 1912.

11 Poelzig, Hans
SUBJECT AREA: Architecture and building[br]b. 1869 Berlin, Germanyd. June 1936 Berlin, Germany[br]German teacher and practising architect, the most notable individualistic exponent of the German Expressionist movement in the modern school.[br]In the last decade of the nineteenth century and in the first of the twentieth, Poelzig did not, like most of his colleagues in Germany and Austria, follow the Jugendstil theme or the eclectic or fundamentalist lines: he set a path to individualism. In 1898 he began a teaching career at the Breslau (now Wroclaw, Poland) Academy of Arts and Crafts, remaining there until 1916. He early introduced workshop practice into the curriculum, presaging Gropius's Bauhaus ideas by many years; the school's workshop produced much of the artisan needs for a number of his buildings. From Breslau Poelzig moved to Dresden, where he was appointed City Architect. It was there that he launched his Expressionist line: which was particularly evident in the town hall and concert hall in the city. The structure for which Poelzig is best known and with which his name will always be associated is the Großes Schauspielhaus in Berlin; he had returned to his native city after the First World War and this great theatre was his first commission there. Using modern materials, he created a fabulous interior to seat 5,000 spectators. It was in the form of a vast amphitheatre with projecting stage and with the curving area roofed by a cavernous, stalactited dome, the Arabic-style stalactites of which were utilized by Poelzig for acoustic purposes. In the 1920s Poelzig went on to design cinemas, a field for which Expressionism was especially suited; these included the Capitol Cinema in Berlin and the Deli in Breslau. For his later industrial commissions—for example, the administrative building for the chemical firm I.G.Far ben in Frankfurt—he had perforce to design in more traditional modern manner.Poelzig died in 1936, which spared him, unlike many of his contemporaries, the choice of emigrating or working for National Socialism.[br]Further ReadingDennis Sharp, 1966, Modern Architecture and Expressionism, Longmans.Theodor Heuss, 1966, Hans Poelzig: Lebensbild eines Baumeister, Tübingen, Germany: Wunderlich.DY
