Hermann Jacques Jordan (Utrecht University, 1917)

Hermann Jacques Jordan (born July 9, 1877 in Paris , † September 21, 1943 in Wageningen , Gelderland province ) was a German-Dutch zoologist. His specialty was comparative physiology.

Life

Jordan's parents were the merchant Julius Jordan and his (Jewish) wife Rosa nee. Levie . When he was nine years old, he came to Eisenach with his family . In 1896 he passed the Abitur examination at the Realgymnasium Eisenach . From Easter 1896 to autumn 1897 he studied natural sciences at the Julius Maximilians University of Würzburg . Like his older brother Leo Jordan , he was active in the Corps Guestphalia Würzburg . His academic teachers included Theodor Boveri and Julius Sachs . As an inactive he moved to the Rheinische Friedrich-Wilhelms-Universität Bonn . There Eduard Pflüger instructed him in experimental physiology. In the fall of 1898 he went to the Naples Zoological Station for a year and a half . As Anton Dohrn's assistant , he investigated the movement of a veil snail . This resulted in the doctoral thesis, which he in February 1901 (age of 23) in Bonn summa cum laude for Dr. phil. received his doctorate.

There was no place for comparative physiology anywhere. Jordan therefore went to the Concilium Bibliographicum in Zurich in 1902 . The University of Zurich appointed him a private lecturer in 1904 . In 1907 he took on a teaching position at the Eberhard Karls University in Tübingen , which appointed him professor in 1911. In autumn 1913 he moved to the University of Utrecht as an assistant , which appointed him to an associate's post in 1915 and to the chair of comparative physiology in 1919 (1919). His inaugural lecture was entitled De vergelijkende physiologie in de geschiedenis der dierkunde . The Rockefeller Foundation helped him out of the space and furnishing problems in his laboratory . It supported the financing of a new building that was inaugurated in November 1935.

He lectured at the Volksuniversiteit Utrecht and gave courses at the Dutch Zoological Station in Den Helder. Friends of Maria Montessori , he was co-founder and curator of the Montessori Lyceum Amsterdam . During the German occupation of the Netherlands, the school lost many Jewish students in the Holocaust . Since 1902 he was married to Nanette van Witsen , a Jew from Rotterdam. Released from his chair on April 1, 1943, he hid with her for the last months of his life.
