Arthur Josef Stanislaus Berson (6 August 1859 – 3 December 1942) was a German〔(Encyklopedia PWN - Berson Artur )〕 meteorologist and pioneer of aerology who was a native of Neu Sandez, Galicia (now Nowy Sącz, Poland). After visiting the gymnasium in Neu Sandez, Berson studied philology in Vienna. He then studied meteorology and geography in Berlin, where he had as instructors Ferdinand von Richthofen and Wilhelm von Bezold. In 1890 he was an assistant to meteorologist Richard Aßmann at the Meteorological Institute in Berlin. During this period of time he was also secretary of the ''Deutschen Verein zur Förderung der Luftschiffahrt'', the first aeronautical organization in Germany. In 1900 he became ''Hauptobservator'' at the newly founded Aeronautics Observatory in Berlin-Tegel, and was later stationed at the Lindenberg Aeronautical Observatory in Beeskow. From 1896 to 1899 Berson was editor of the magazine ''Zeitschrift für Luftfahrt und Physik der Atmosphäre'' (Magazine for Aviation and Physics of the Atmosphere). == Scientific research == Berson is largely known for his scientific hot-air balloon expeditions. On 4 December 1894, he ascended to a then-record altitude of 9,155 meters aboard the hydrogen balloon ''Phoenix''. On 10 January 1901, with artillery officer Alfred Hildebrandt (1870–1949), he travelled from Berlin to Markaryd, Sweden in a balloon, thus being the first to cross the Baltic Sea by air. On 10 January 1902, with balloonist Hermann Elias (1876–1955), he set the German long-distance ballooning record, as the two men journeyed from Berlin to Poltava in the central Ukraine (1,470 kilometers in 30 hours). During the 1890s, he was involved in international "simultaneous ascents" with balloonists from other nations. These ascents were performed in order to study variances of climatic conditions above different locations in Europe, to work to bring about uniformity in methods of observation, and to create increased cooperation among nations in the new science of aerology. On 31 July 1901, with meteorologist Reinhard Süring, he took his most celebrated ascent. Starting from Berlin-Tempelhof aboard the ''Preussen'', Berson and Süring ultimately reached a height of 10,800 meters above sea level. At 6000 m. they required compressed oxygen, at 10,000 m. both scientists were rendered unconscious, and after regaining consciousness were able to land their balloon near Briesen, 7.5 hours after their flight began. Their record ascent had significant scientific importance. Climatic data taken from simultaneously released unmanned sounding balloons agreed with the information gathered from the Berson/Süring ascent. Now scientists such as Richard Aßmann no longer had any reason to distrust temperature readings taken from unmanned balloons, an important factor that led to the discovery of the stratosphere by Aßmann and Teisserenc de Bort in 1902. Another important aspect of high altitude flight involved physiological problems that balloonists could experience when exposed to conditions at great heights. Here, Berson assisted physiologists Hermann von Schrötter and Nathan Zuntz with pioneer experiments in the field of aviation medicine. He undertook high altitude balloon ascents with the two physiologists, and conducted studies of decompression sickness with a pneumatic chamber located at the ''Jüdischen Krankenhaus'' (Jewish Hospital) in Berlin. Other significant accomplishments by Berson include climatic studies with weather kites off of Svalbard, pioneer meteorological observations from German East Africa, and aerological research over the Amazon Basin. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Arthur Berson」の詳細全文を読む スポンサード リンク
