for development as a zoological garden. The district added to that plot and in 1921, the Chicago Zoological Society was established. Serious construction did not begin until 1926, after a zoo tax was approved. Construction slowed during the Great Depression, but regained momentum by late 1931. Construction went on at an increased pace and the zoo opened on July 1, 1934. By the end of September 1934, over one million people had visited the new zoo; the four millionth visitor was just two years later.
The 1950s saw the addition of a veterinary hospital, a children's zoo, and the famous central fountain. The zoo went through a decline in the 1960s until a large bond issue from the Forest Preserve District, close attention to zoo governance, and visitor services saw the zoo recreate itself as one of the nation's best. Tropic World, the then-largest indoor zoo exhibit in the world, was designed by French architect Pierre Venoa and opened in three phases (
