Chicago Zoological Society and the Brookfield Zoo
The "Chicago Zoological Society" focuses on animal conservation and linking people with nature and wild life. After the Brookfield Zoo was started in 1934, this society's reputation for working as part of the animal conservation and care increased.
The historical firsts of the society include indoor exhibits of multiple species, "zoo nutrition residencies", animal husbandry methods, medical care which is inclusive of gorilla's brain surgery. When talking about Chicago zoos, especially the "Bark field Zoo", their contribution should not be ignored.
