Caption: Jacques Loeb (1859-1924), German-US physiologist. Loeb held several professorships before becoming a member of the Rockefeller Institute for Medical Research in 1910. Loeb researched simple plant and animal reactions (tropisms) towards or away from stimuli, such as light or gravity. He argued that such behaviour could also be applied to higher animals and that even humanity's morals and ethics were due to combinations of tropisms. His experiments on marine invertebrates achieved artificial parthenogenesis of sea urchin eggs. He conducted these experiments at the Marine Biological Laboratory (MBL), Woods Hole, Massachusetts, USA.
