Konrad Lorenz was an Austrian zoologist and ethologist, best known for his pioneering work in animal behavior. He is often regarded as one of the founders of modern ethology, the study of animal behavior in natural environments. Lorenz is famous for his research on imprinting, a process where young animals form attachments to the first moving object they encounter, typically their mother. In 1973, Lorenz was awarded the Nobel Prize in Physiology or Medicine alongside Karl von Frisch and Nikolaas Tinbergen for their contributions to the understanding of animal behavior. His work has had a lasting impact on the fields of psychology, biology, and ecology, influencing how we understand the behavior of both animals and humans.
