Just after World War II, a new branch of science was born – ethology, the study of animal behavior. The first ethologist to come to prominence in the scientific community was Austrian Konrad Lorenz.
In 1973 Lorenz won the Nobel Prize, along with colleagues Karl von Frisch and Niko Tinbergen, for their discoveries concerning animal behavioral patterns. They discovered the phenomenon of imprinting, in which young animals socially bond to the first moving object they encounter.
Some of Lorenz’ views were expressed in his popular book On Aggression (1966), wherein he asserted that human aggressive impulses are to a degree inborn, and drew analogies between the aggression demonstrated in both human and animal territorial behavior. These assertions made decades ago have engendered considerable controversy. Some saw Lorenz’ views as an attempt to whitewash human atrocities like the Nazi persecution of the Jews.
