During the 1920s, the City of Houston developed Hermann Park based in part on plans by Arthur Comey and George Kessler on land donated by George H. Hermann in 1922. The Houston Zoological Garden opened on the park grounds two years later. The park complex expanded with the construction of Museum of Natural History and a full-size golf course. Several smaller buildings were also added, as well as several curving roads to provide automobile access through the grounds. Will Hogg donated another large tract for an expansion to the park.
