Ragnar Berg (1873-1956) was a Swedish-born biochemist and nutritionist who worked most of his adult life in Germany. He is best known for promoting the importance of acid-base balance and inorganic minerals like calcium in the diet; later in life he endorsed vegetarianism and ways to prolong the human life span. He also invented the alkaline dietary supplement Basica,〔http://www.basica.de/en〕 which Volkmar Klopfer manufactured and marketed from 1925. ==Life== Ragnar Berg was the son of the respected Swedish historian and archaeologist Wilhelm Berg (1839-1915) and his first wife, Ulrika Charlotta Emerentia "Emy" Gumaelius (1846-1902). He married Ella Buscher in 1902, and they had two sons, Gunnar Wilhelm Emil (1907-1974) and Alf Ragnar Wilhelm (1912-1994).〔Christian Rummel, "Ragnar Berg: Leben und Werk des schwedischen Ernährungsforschers und Begründers der basischen Kost", Peter Land, 2003.〕 Berg was recruited by Karl Lingner to the Dresden Center for Dental Hygiene (''Zentralstelle für Zahnhygiene'') in 1902, where he met dentist Carl Röse (1864–1947), his long-time experimental partner. From 1909 to 1921 Berg headed the physiology lab at the homeopathic sanatorium founded by Heinrich Lahmann at Weisser Hirsch near Dresden,〔William Shurtleff, Akiko Aoyagi, ''History of Soybeans and Soyfoods in Africa (1857-2009): Extensively Annotated Bibliography and Sourcebook'', Soyinfo Center, 2009, p.200.〕 researching vitamins, trace elements and the metabolism of minerals.〔Friedhelm Kirchfeld, Wade Boyle, ''Nature doctors: pioneers in naturopathic medicine'', Medicina Biológica, 1994, p.148.〕 The laboratory burned in 1915. In 1921, he was dismissed from Lahmann's Sanatorium, since business had dried up during World War One, and its new directors wanted to focus on the more lucrative fields of psychoanalysis and gynecology. Berg, personally stung, felt that "the directors did not value his scientific approach to nutrition."〔David F. Smith, Jim Phillips, ''Food, science, policy and regulation in the twentieth century: international and comparative perspectives'', Routledge, 2000.〕 He continued conducting experiments on himself and analyzing foodstuffs from a home laboratory. From 1927 to 1932, he headed his own nutrition department at the Dresden-Friedrichstadt Hospital; in 1934 he was invited to the "Rudolf Hess Hospital in Dresden-Johannstadt.〔Eike Reichardt, ''Health, 'Race' and Empire: Popular-Scientific Spectacles and National Identity in Imperial Germany, 1871-1914'', 2008, pp.126-7.〕 However, his funding ran out two years later. Only during the 1940s was he able to get federal funds for his "war-related" work. In March 1945, Berg and his wife, Ella, fled bombed-out Dresden for Berlin and then to Stockholm, Sweden. (Neither their house nor his lab in the hospital had been damaged, however.) They lived in his native Sweden until her death from a heart attack at the end of 1954. Berg was very lonely, his health deteriorated, and he spent many months in the hospital before moving to his son's home north of Hamburg, where he died a few months later of old age and metastatic prostate cancer. He was nearly blind by this time. 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「Ragnar Berg」の詳細全文を読む スポンサード リンク
