Konrad Zacharias Lorenz was an Austrian scientist who specialised in zoology and ornithology; however he made his biggest contribution in the field of ethology and is regarded as the founding father of this particular branch of science. Ever since he was a child, Zacharias was attracted towards animals and keenly observed them. Such was his love for animals that during his student years he developed a large collection of exotic fauna. He started his career as an academic but his scientific pursuits were interrupted by the World War II. Inducted into the German Army as a psychologist, he witnessed the cruelties inflicted by the Nazi soldiers on the prisoners and harboured a deep regret for having served for their horrific cause. Lorenz made path breaking discoveries in zoology, ornithology and ethology throughout his long career, as one of the leading scientist of the world. He won plenty of accolades and award in his life due to the outstanding contributions that he had made to the world of science. It would not be an exaggeration by any stretch of imagination that Konrad Lorenz is a scientist who belongs in the pantheon of the greatest scientists that the world has ever seen.
