Before he created the writer-persona of Dr Seuss, Geisel was an artist of another kind. In his spare time he created sculptures of interesting and strange creatures, using parts of real animals. Of course it is not as grotesque as it sounds- the animal parts were given to Theodor after the animals died of natural causes. His father was the superintendent of parks in Massachusetts at the time when a young Geisel was working as a fledgling author and illustrator. When zoo and park animals crossed the rainbow bridge, Geisel’s father sent him the various animals’ parts to help him create some whacky characters.
Horns, antlers, beaks, and all sorts were used by Geisel to build some of the most fantastical animals that, unsurprisingly, look like they have jumped straight out of a Dr Seuss picture book.
