Konrad Zacharias Lorenz (1903 - 1989) was an Austrian zoologist, animal psychologist, and ornithologist, winning the Nobel prize for Physiology or Medicine in 1973.
He is often regarded as one of the founders of modern Ethology, developing an approach that began with an earlier generation. He studied instinctive behavior in animals, and rediscovered the principle of Imprinting (originally described by Douglas Spalding in the 19th century) in the behavior of Nidifugous birds.
He was influential in the development of the Theory of Instinct (see Psychological Aspects of Biodanza).
