thumb Hermann Jakob Knapp (March 17, 1832 – April 30, 1911) was a German-American ophthalmologist and otologist. ==Biography== He was born in Dauborn, Nassau. He earned his medical degree from the University of Giessen in 1854. As a young physician he studied with Franciscus Cornelis Donders in Utrecht, William Bowman in London, Albrecht von Graefe in Berlin and Hermann von Helmholtz in Heidelberg. From 1860 until 1868 he was a professor of ophthalmology at Heidelberg. He emigrated to New York City, where he worked as a surgeon. In 1869 he founded the New York Ophthalmic and Aural Institute, which from 1913 to 1939 was called the Herman Knapp Memorial Hospital. In 1882, he was made professor of the New York University Medical College. In 1888, he was appointed professor of ophthalmology at the College of Physicians and Surgeons, Columbia University, and in 1902 he became emeritus professor. His son, Arnold Knapp (1869–1956) was also a noted ophthalmologist. In 1869, with Salomon Moos (1831–1895), he founded the "Archives of Ophthalmology and Otology" (''Archiv für Augen- und Ohrenheilkunde''), an international scientific monthly journal that was published in Wiesbaden (ing German) and New York (in English). In 1878 the archives split into two independent entities; as the "Archives of Ophthalmology" (''Archiv für Augenheilkunde'') and the "Journal of Otology" (''Zeitschrift für Ohrenheilkunde''). His name is lent to the eponymous "Knapp streaks"; also known as angioid streaks, which are tiny breaks in the elastin-filled tissue in the back of the eye. He devised his own version of an ophthalmotrope, a device used in physiological optics to demonstrate the action of ocular muscles individually or in various combinations. Several instruments used in eye surgery bear his name, including the "Knapp trachoma forceps". 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「Hermann Jakob Knapp」の詳細全文を読む スポンサード リンク
