Definition of Lorenz, Konrad
- (1903–89), Austrian zoologist; full name Konrad Zacharias Lorenz. He pioneered the science of ethology, emphasizing innate rather than learned behaviour or conditioned reflexes. Lorenz extrapolated his studies in ornithology to human behaviour patterns, and compared the ill effects of the domestication of animals to human civilizing processes. He shared a Nobel Prize in 1973 with Karl von Frisch and Nikolaas Tinbergen.
