Karl Hermann Knoblauch (11 April 1820 – 30 June 1895) was a German physicist. He is most notable for his studies of radiant heat. He was one of the six founding members of the Deutsche Physikalische Gesellschaft at Berlin on 14 January 1845.As a researcher and teacher at the University of Marburg, 1849–53, he produced valuable experimental demonstrations about the nature of diamagnetism. Knoblauch's student and collaborator on the diamagnetism work was John Tyndall. Tyndall and Knoblauch maintained a correspondence on and off over the next 25 years.

  • Карл Герман Кноблаух (нем. Karl-Hermann Knoblauch; 1820—1895) — немецкий физик.После завершения университетского курса в 1847 году Кноблаух два года в качестве приват-доцента читал в Берлине лекции по физике, затем был назначен экстраординарным профессором в Марбурге (1849—1853), откуда перешёл в 1853 году в Университет Галле в качестве ординарного профессора в Галле.Кноблаух был известен главным образом своими работами над явлениями лучистого тепла; ему и Меллони наука была обязана основными положениями этого отдела физики; из других работ Кноблауха выделяется исследование, проведённое им вместе с английским физиком Тиндалем, над магнитными свойствами кристаллов. С 1878 года Кноблаух был президентом королевской саксонской Леопольдовой академии немецких естествоиспытателей. (ru)
  • Karl Hermann Knoblauch (Berlim, 11 de abril de 1820 — Baden-Baden, 30 de junho de 1895) foi um físico alemão. É conhecido por suas investigações sobre o calor radiante. Foi um dos seis fundadores da Deutsche Physikalische Gesellschaft em Berlim, em 14 de janeiro de 1845. O pai de Knoblauch foi um bem estabelecido fabricante de tecidos de seda em Berlim. Apesar da pressão de seu pai para ele participar dos negócios familiares, Knoblauch optou por estudar matemática e ciências na Universidade Humboldt de Berlim. Lá tornou-se um dos mais destacados alunos do laboratório de Heinrich Gustav Magnus. Em sua tese de doutorado, comcluida em Berlim em 1847, descreveu experimentos fundamentais que estabeleceram algumas das propriedades ópticas da radiação térmica (também conhecida como radiação infravermelha). Em um artigo descrevendo estes experimentos Knoblauch escreveu que fatos experimentais são "as únics coisas permanentes em ciência", enquanto modelos abstratos são "transitórios" e devem ser tratados com precaução e mantidos separados de fatos, ponto de vista também seguido por Magnus. Como pesquisador e professor na Universidade de Marburg, de 1849 a 1853, produziu demonstrações experimentais fundamentais sobre a natureza do diamagnetismo. John Tyndall foi aluno e colaborador de Knoblauch no trabalho sobre diamagnetismo, e mantiveram correspondência durante vinte e cinco anos. Knoblauch mudou-se para a Universidade de Halle-Wittenberg em 1853, onde permaneceu o resto de sua carreira. Durante os primeiros anos em Halle nada publicou. Mais tarde suas publicações não foram mais tão frequentes quanto haviam sido antes de sua mudança para Halle. Durante seus anos em Halle, além de professor e pesquisador, desempenhou várias funções administrativas na ciência da Alemanha, tendo sido presidente da Academia Leopoldina de 1878 a 1895. Também foi reitor da Universidade de Halle-Wittenberg por algum tempo. (pt)
  • Karl Hermann Knoblauch (11 April 1820 – 30 June 1895) was a German physicist. He is most notable for his studies of radiant heat. He was one of the six founding members of the Deutsche Physikalische Gesellschaft at Berlin on 14 January 1845. Knoblauch's father was a well-to-do silk fabrics manufacturer in Berlin. Despite pressure from his father to enter the family business, Knoblauch in his early 20s opted to study mathematics and science at the University of Berlin. There he became one of the star students in the laboratory of Gustav Magnus. Knoblauch's doctorate, completed in Berlin in 1847, described valuable experiments that established some of the optical properties of radiant heat (a.k.a. infrared radiation). In an article describing these experiments Knoblauch wrote that experimental facts are "the only permanent things in science", while abstract models are "transitory" and should be treated with caution and kept separate from the facts, a view that Magnus maintained also. As a researcher and teacher at the University of Marburg, 1849–53, he produced valuable experimental demonstrations about the nature of diamagnetism. Knoblauch's student and collaborator on the diamagnetism work was John Tyndall. Tyndall and Knoblauch maintained a correspondence on and off over the next 25 years. Knoblauch moved to the University of Halle in 1853, and remained there for the rest of his career. During his first few years at Halle he did not publish anything. Later his publications were still not as frequent as they had been before moving to Halle. In his Halle years, apart from science teaching and research, he also gave his time to various administrative functions in German science including being president for 17 years of the German Academy of Sciences. He was also the rector (chief administrative officer) of the University of Halle for a while. (en)
