Konrad Lorenz

Born 7 Nov 1903; died 27 Feb 1989 at age 85. Austrian zoologist, who founded modern ethology (the study of animal behaviour by means of comparative zoological methods). He was known affectionately by his pupils as the “father of the grey geese” which he studied. His ideas revealed how behavioral patterns may be traced to an evolutionary past, and he was also known for his work on the roots of aggression. He shared the 1973 Nobel Prize for Physiology and Medicine for developing a unified, evolutionary theory of animal and human behaviour. He was also a vehement environmentalist, criticizing prodigality and believed that nature protection is necessary for the preservation of humanity. Even late in life, he participated in demonstrations even if in conflict with government and authorities.
