Charles Sidney Burrus (October 9, 1934 in Abilene, Texas - April 3, 2021) was an American electrical engineer and the Maxfield and Oshman Professor Emeritus of Electrical and Computer Engineering at Rice University in Houston, Texas. He is widely known for his contributions to digital signal processing, especially FFT algorithms, IIR filter design, and wavelets.
Achille Joseph Urbain (9 May 1884 – 5 December 1957) was a French biologist born in Le Havre.
Giuseppe Nazzareno Sterzi (1876–1919) was an Italian anatomist, neuroanatomist and medical historian. Although his research activity encompassed no more than fifteen years, the themes treated by Sterzi are relevant to neuroanatomy and history of anatomy. Sterzi’s research on comparative neuroanatomy and embryology were acknowledged by numerous contemporaries (Bardeleben, Chiarugi, Edinger, Eisler, Johnston, Krause, Nicolas, Obersteiner, Sobotta) and many of his discoveries were soon incorporated into anatomy textbooks. Sterzi was awarded several scientific prizes, among which were the ‘Premio Fossati’ of the Reale Istituto Lombardo di Scienze e di Lettere, Milano in 1909 and the ‘Prix Lallemand’ of the Académie des Sciences de l'Institut de France, Paris in 1912.
Gabriel Steiner (26 May 1883, Ulm – 10 August 1965, Detroit) was a German-American neurologist known for his research of multiple sclerosis. In his studies, he postulated a link between multiple sclerosis and certain forms of spirochetes.Of Jewish ancestry, he studied medicine at the universities of Munich, Würzburg, Freiburg and Strasbourg, receiving his doctorate at the latter university in 1910. In 1913 he qualified as a lecturer in neurology and psychiatry, and from 1920, worked as an associate professor at the University of Heidelberg. Here, he was also head of the laboratory for pathological anatomy at the psychiatric-neurological clinic.In 1936 he emigrated to the United States, where from 1937 to 1954, he served as a professor of neurology and neuropathology at Wayne State University School of Medicine in Detroit. In retirement, he was director of the Michigan Multiple Sclerosis Center.
Rudolf Stähelin, surname also spelled Staehelin (28 July 1875, Basel – 26 March 1943, Basel) was a Swiss internist.
He studied medicine at the Universities of Basel, Tübingen and Munich, obtaining his doctorate at Basel in 1901. He briefly served as an assistant physician at the Civic Hospital in Basel, then was a lecturer at the Universities of Basel (from 1902), Göttingen (1906) and Berlin (from 1907). From 1911 until 1943, he was a professor of internal medicine and director of the medical clinic at Basel.His research involved studies on tuberculosis, respiratory, circulatory, metabolic and infectious diseases. With Gustav von Bergmann, he published the second edition of the Handbuch der inneren Medizin (1925-1931).
Hans Otto Friedrich Schlossberger (born 22 September 1887 in Alpirsbach, died 27 January 1960 in Stuttgart) was a German physician, who was known for his research in immunology, medical microbiology, epidemiology and antimicrobial chemotherapy, especially on syphilis, typhus, gas gangrene, diphtheria, erysipeloid of Rosenbach, tuberculosis, malaria and leptospirosis. He was one of the leading immunologists and bacteriologists of Germany during his lifetime, and was a student and collaborator of the Nobel laureates Paul Ehrlich and Emil von Behring, two of the principal founders of the field of immunology.
From 1946 to 1955, he was Professor of Medical Microbiology and Infection Control and Director of the Institute for Medical Microbiology and Infection Control at the Goethe University Frankfurt, and also served as Dean of the Faculty of Medicine 1952–1953. He edited the journal Medical Microbiology and Immunology and the influential book Experimental Bacteriology.
Harald Ernst Malmsten Schering (November 25, 1880 – April 10, 1959) was a German physicist born in Göttingen. He is best known for his work in high voltage electricity and the Schering Bridge used in electrical engineering. Schering was the son of Ernst Schering, mathematician at the Göttingen Observatory. His mother came from a family of Swedish academics who worked with Ernst to translate works from French and Italian. Harald grew up with his two siblings in Göttingen and studied physics at the University of Göttingen. In 1903 he worked at the Geophysical Institute and obtained a Ph.D. in 1904 under Eduard Riecke with work on the Elster-Geitel dispersal apparatus. Beginning in 1905 he was a scientific assistant at the Physics and Technology Institute in Berlin Charlottenburg; today known as the Physikalisch-Technische Bundesanstalt (PTB). His work at the PTB under Emil Warburg primarily dealt with high voltage/high current research and development, and in 1914 he developed a measurement methodology for examining current transformers. In 1914 he was drafted into the First World War and was injured in 1916. In 1918 he became head of the high-voltage lab, succeeding Karl Willy Wagner. In 1919 he attained the title of professor at PTB with an annual salary of 4500 Marks and 1500 Marks as housing allowance. In 1924 he wrote a book on insulators in high voltage. A new institute was established in Hannover, buts construction was delayed by the war. Beginning in 1927, Schering was a professor of electrical engineering and high voltage technology at the Technical University of Hannover (today known as the Leibniz University Hannover). In 1933, he signed the Vow of allegiance of the Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State. He retired in 1949 but continued to work at the PTB until 1954 when Gerhard Pfestdorf took up a position to head the institution.Schering is remembered for invention of the Schering Bridge, which he developed along with Ernst Alberti is an AC bridge circuit used to measure capacitance and the dissipation factor of capacitors. Schering received a Golden Doctorate from the University of Göttingen in 1954 and an honorary doctorate from Braunschweig. He was awarded the Great Cross of Merit by the Federal Republic of Germany in 1957.
Max Robitzsch (2 February 1887 – 10 June 1952) was a German meteorological scientist and university professor. He invented the "Robitzsch Actinograph", a type of pyranometer and wrote numerous scientific books and articles.
He was born in Höxter, Province of Westphalia. He also undertook an expedition into the Scandinavian arctic to research atmospheric phenomena, spending the 1912/1913 winter in Spitsbergen, Norway. His mission, together with Kurt Wegener, brother of Alfred Wegener, was to set up a meteorological observatory for the German Geophysical Observatory, which they did at the Crossbai, Ebeltofthafen (Ebeltofthamna in Norwegian). During the long winter stay, they and two helpers performed 275 pilot balloon soundings, 98 tethered balloon soundings and 19 probe launches with the help of a hang glider. As of 2000, only some archeological remains of the obersvatory could be found.For much of his life (since at least 1917), he worked as a professor at the Meteorological Observatory Lindenberg (German Wikipedia) in Lindenberg, Brandenburg. During the Cold War, he there undertook numerous extensive radio sounding studies of the atmosphere with weather balloons, reputedly at the behalf of the Soviet occupation forces in East Germany.During January to May 1950, he was director of the Meteorologisches Observatorium Lindenberg, before later on becoming professor at (and possibly the director of) the Geophysical Institute of Leipzig, later subsumed in the University of Leipzig.
Claudius Regaud (born 30 January 1870 in Lyons, France; died 29 December 1940 in Couzon-au-Mont-d'Or, France) was a French medical doctor and biologist, one of the pioneers in radiotherapy at the Curie Institute.
Louis Étienne Ravaz or Louis Ravaz (Saint-Romain-de-Jalionas, Isère, 1863 — Montpellier, 1937) was a specialist of ampelography and one of the creators of modern viticulture. In 1892, he founded the grape research station of Cognac (French: Station viticole de Cognac), that he directed for several years. He was professor of viticulture (and from 1919 director) at the National School of Agriculture of Montpellier (École nationale d’agriculture de Montpellier). He contributed to the diffusion of the use of the American varieties in the regions affected by French blight (Phylloxera) and investigated the pathologies of the grapevine. He published several works on viticulture. With Pierre Viala, he described the causes of the black-rot disease of grapevine and founded the "Revue de viticulture".
He was the taxon author of:
Guignardia Viala & Ravaz, Bull. Soc. mycol. Fr. 8: 63 (1892)
