Konrad Lorenz
In the early 1980s the term 'human–animal bond' was officially coined by Leo K. Bustad, who delivered a summary lecture on the Human-Pet Relationship on October 28, 1983, at the International Symposium in Vienna. This symposium was held in honour of Konrad Lorenz, and during his lecture, Bustad praised him for his work on the human–animal bond and encouraged others to build on Lorenz's work on the subject. In the early 1970s, Konrad Lorenz had developed the field of ethology with his landmark research on the imprinting of behaviours in geese.
