(Moritz Wilhelm) Hugo Ribbert (1 March 1855 in Hohenlimburg – 6 November 1920 in Bonn) was a German professor of pathology.
Ribbert studied at Bonn, Berlin and Strassburg. In 1883 he was appointed Professor extraordinarius at Bonn. In 1892 he became professor at Zurich. In 1900 he moved to Marburg University; in 1903 he moved to Göttingen University; and in 1905 he returned to Bonn.[1]
An 1881 conference report of Ribbert is considered to be the first description of cells infected with the cytomegalovirus.[2][3] In 1905 Ribbert proposed an embryonal origin for cancer (Cohnheim-Ribbert theory of cancer).[4]
