Konrad Lorenz (1903-1989). Caricature of the Nobel Prize-winning Austrian zoologist Konrad Lorenz being followed by a duckling. Lorenz studied medicine in Vienna before changing to zoology. His first discovery as a scientist occurred when he was given a one-day-old duckling that followed him around as if he were its mother. Together with the Dutch zoologist Niko Tinbergen, he founded a branch of animal behaviour called ethology, based on observing the instinctive behaviour of animals in the wild. They shared the 1973 Nobel Prize for physiology or medicine with Karl von Frisch.
