Richard Liebreich
Richard Liebreich (30 June 1830 – 19 January 1917) was a German ophthalmologist and physiologist who was a native of Königsberg. He was of Jewish ancestry.
In 1853 he earned his doctorate at Halle, and from 1854 until 1862 was an assistant to Albrecht von Graefe (1828-1870) in Berlin. He subsequently practiced medicine in Paris (from 1862) and London (from 1870), where he was head of ophthalmology at St. Thomas Hospital. He later retired from medicine and moved back to
deaf patient with retinitis pigmentosa, who had two brothers with the same symptoms. Three years later, one of his students, Richard Liebreich, examined the population of Berlin for disease pattern of deafness with retinitis pigmentosa. Liebreich noted Usher syndrome to be recessive, since the cases of blind-deafness combinations occurred particularly in the siblings of blood-related marriages or in families with patients in different generations. His observations supplied the first proofs for the coupled transmission of blindness and deafness, since no isolated cases of either could be found
