Book Review

Gustaf Retzius (1842–1919), the Swedish anatomist and anthropologist, and Camillo Golgi were contemporaries. They met on several occasions and came in closer contact when Golgi, together with Ramón y Cajal, was awarded the Nobel Prize in Physiology or Medicine in Stockholm in 1906. Retzius came from an illustrious family. His father was professor of anatomy at Karolinska Institutet and Gustaf himself made a fast career. At 35, he was appointed to a professorship in histology, especially created for him at Karolinska Institutet, and later he became professor of anatomy in the same institution. Retzius was exceedingly productive, and published more than 300 scientific papers, most of which dealt with the nervous system and sensory organs. The majority of these were included in his magnificent volumes Biologische Untersuchungen, Neue Folge (Biological Investigations, New Series), which appeared from 1890 to 1921, and in Das Gehörorgan der Wirbelthiere (“The Acoustic Organ of Vertebrates”, 1881 and 1884), which may be his internationally better known contribution. Much of his work, especially on invertebrates, was based on Ehrlich's methylene blue method, but he also used the Golgi method early on. Particularly his studies of the innervation of the sensory organs became of great importance for the support of the neuron doctrine. His standing internationally was reflected in his membership in many of the most prominent academies abroad, as well as in invitations to him to give a “Croonian Lecture” in 1908 and “The Huxley Lecture” in 1909.
