How Golgi Shared the 1906 Nobel Prize in Physiology or Medicine with Cajal

There were four proponents for Golgi that year, namely Hertwig, professor of comparative anatomy from Berlin, Kölliker, professor of anatomy from Würzburg, and two Swedes, Gustaf Retzius, former professor of anatomy from Stockholm, and Carl Magnus Fürst, professor of anatomy from Lund. Kölliker, Retzius and Fürst proposed Golgi and Cajal. Retzius, however, proposed Cajal alone as an alternative. Cajal's nomination was also supported by, in addition, Ziehen, professor of psychiatry and neurology from Berlin, and by Emil Holmgren, from Stockholm.
