The Milwaukee County Zoo is a zoo in Milwaukee, Wisconsin, operated by the Milwaukee County Parks Commission. The zoo houses 1,800 animals and covers an area of 200acre. It is noted for the second birth of polar bears and siamangs in captivity and for their locally famous gorilla Samson, who lived from 1950 to 1981 and whose bones are now on display at the Milwaukee Public Museum. The zoo is also home to one of the largest group of bonobos in one location outside their native Democratic Republic of the Congo, and has two cheetahs from the National Zoo in Washington, DC.HistoryThe Washington Park ZooWest Park Zoo opened in 1892, displaying small mammals and birds. The following year, the zoo added two cinnamon bears and created an iron bear den. In 1899, the zoo constructed a $2,137 herbivore building that housed a variety of animals. In 1900, West Park Zoo became Washington Park Zoo and two years later, the zoo was expanded to 23acre. Even with the Great Depression of the 1930s, the zoo prospered, creating a bear den that resembled bears' natural habitat. In 1931, the zoo's bear collection contained 37 specimens. By 1937, the Washington Park Zoo was beginning to show its age. A reptile exhibit was opened in the main zoo building in 1942. George Speidel, zoo director at this time, began planning a new zoo.
