Chuck Hoberman (born 1956 in Cambridge, Massachusetts, USA) is an inventor of folding toys and structures, most notably the Hoberman sphere. He won the Chrysler Design Award for Innovation and Design in 1997 and was a finalist for the 2000 Smithsonian National Design Award.
In addition to toys such as the Hoberman sphere, the largest of which resides at Liberty Science Center in Jersey City, New Jersey, Hoberman created the BrainTwist, a hard plastic tetrahedron that folds, stellates, and becomes self-dual while having a component that rotates similarly to a Rubik's Cube. Likewise, Chuck Hoberman's Pocket Flight Ring is a folding, throwable toy resembling a chakram.
Hoberman also has designed folding architectural structures like the Expanding Hypar (1997) at the California Museum of Science and Industry, the Hoberman Arch, the centerpiece of the medals plaza for the 2002 Salt Lake City Olympics, to a retractable dome featured at the World's Fair 2000 in Hanover, Germany. His artwork has been exhibited at international museums including New York's Museum of Modern Art, the Centre Georges Pompidou in Paris, and the Mycal Otaru Bay in Hokkaidō, Japan.
Hoberman has also created the Expandagon Construction System, a kind of construction toy.
