SALOMONSEN, CARL JULIUS (1849–1924), Danish physician and bacteriologist. Born in Copenhagen, Salomonsen began his bacteriological investigations in 1873 as an assistant at the Copenhagen Municipal Hospital. He studied with Julius Friedrich Cohnheim (1839–84), Robert Koch (1843–1910), and Louis Pasteur (1822–95), and then introduced bacteriology as a scientific discipline into Denmark and was appointed lecturer on bacteriology at the University of Copenhagen. Salomonsen was professor of pathology from 1893 to 1920 and rector magnificus (1919–20). With the introduction of serotherapy and the discovery of diphtheria antitoxin, Salomonsen established a serotherapeutic laboratory in 1895 which became the foundation of the well-known Danish State's Serum Institute. Salomonsen was known as the last polyhistor at the University of Copenhagen. A great number of monographs on various branches of science afford evidence of his extensive knowledge and interests.
