Forest Park Zoo is a zoo in Springfield, Massachusetts, in Forest Park, near where Dr. Suess spent much of his early life. Theodor Robert Geisel, Dr. Suess's father was a curator here. Many of the species of animals featured at the zoo inspired his artwork. The elder Geisel would often send his son, horns and other parts from animals that had died or had molted, which the younger Geisel would use to make sculptures.
