Heini Hediger

Heini Hediger (1908-1992) was a Swiss biologist noted for work in proxemics in animal behavior and is known as the "father of zoo biology". Hediger was formerly the director of Tierpark Dählhölzli (1938-1943), Zoo Basel (1944-1953) and Zürich Zoo (1954-1973).

Psychology

Hediger described a number of standard interaction distances used in one form or another between animals. Two of these are flight distance and critical distance, used when animals of different species meet, whereas others are personal distance and social distance, observed during interactions between members of the same species.[1] Hediger's biological social distance theories were used as a basis for Edward T. Hall's 1966 anthropological social distance theories.

In the 1950s, psychologist Humphry Osmond developed the concept of socio-architecture hospital design, such as was used in the design of the Weyburn mental hospital in 1951, based partly on Hediger’s species-habitat work.

Zoo biology

In 1942 the Swiss biologist and ethologist Heini Hediger made a revolutionary breakthrough. He developed the science of wild animals kept in human care and published this concept of a new, special branch of biology, called “zoo biology”. The main statement is that animals in zoos are not to be considered as “captives” but as “owners of property”, namely the territory of their enclosures. They mark and defend this territory as they do in the natural environment and if the enclosures contain these elements which are of importance to them also in their natural environment, they have neither need nor desire to leave this property, but to the contrary, stay within it, even when they would have the opportunity to escape, or return to this “safe haven”, should they by accident have escaped. He consequently emphasized that the quality of the enclosures (“furnishing”, structure) is equally, or even more important than quantity (space, dimensions) and substantiated this with observations in the natural habitat. Among many other things he made clear that animals in the natural habitat do not need huge spaces, when all their needs can be satisfied within close range, that, in fact, animals do not move about for pleasure but to satisfy their needs. Zoo biology therefore implies that the life of animals in their natural surroundings must be studied in order to provide them with appropriate keeping conditions in human care. In animal husbandry, the aim of this concept — guided by the maxim “changing cages into territories” — was to meet the biological and ethological requirements of the exhibited animals. Hediger's publications had an enormous positive impact on the keeping of wild animals in human care in particular also in the construction of enclosures and the planning of zoos.

In the 1950s, he began promoting the concept of training zoo animals to elicit biologically suitable behavior and to afford the animal exercise and mental occupation. Further, he observed that in some cases training increased the opportunity for the zoo keeper to give needed medical treatments to the animal. He also referred to zoo animal training as “disciplined play”.

In the 1940s he defined the four main tasks of zoos:

  1. Recreation
  2. Education
  3. Research
  4. Conservation

In the 1960s, he defined the seven aspects of a zoological garden considering people, money, space, methods, administration, animals and research, in that order. He reintroduced the new concept of zoo biology and dealt with such matters as food, causes of death, zoo architecture, the meaning of animal to man and man to animal, the exhibition value of animals, and the behavior of humans in zoos.
