Chuck Hoberman (born 1956) is an artist, engineer, architect, and inventor of folding toys and structures, most notably the Hoberman sphere.^[1][2]

Hoberman's father was an architect, and his mother, Mary Ann Hoberman, was a children's book author.^[3] He wanted to be an artist from an early age, doing drawing and painting, and eventually taking courses at Cooper UnioninNew York City. He studied liberal artsatBrown University, and went on to earn a bachelor's degreeinsculpture from Cooper Union in 1979, and a master's degreeinmechanical engineering from Columbia University. At some point during his education, he was asked to produce a sculpture that could move. He made a work that unrolled colored plastic sheets on the floor, and he became fascinated with kinetic art.^[3] Finishing his formal education, he then went to work for a robotics engineering firm, where he added computer modeling (CAD-CAM) to his skills.^[3] After six years, he left to pursue his artistic and technical interests full-time.

The two largest Hoberman spheres are motorized, 5.5–6 m in diameter, and suspended above open rooms in science centers. One is displayed in the AHHAA Science Center in Tartu, Estonia, and the second is displayed in Liberty Science CenterinJersey City, New Jersey.

Hoberman has designed other folding architectural structures, such as 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; and a retractable dome featured at the World's Fair 2000inHanover, Germany. His artwork has been exhibited at international museums including the New York's Museum of Modern Art, the Centre Georges PompidouinParis, and the Mycal Otaru Bay in Hokkaidō, Japan.

Hoberman has installed permanent building facades that transform in transparency at the Wyss Institute for Biologically Inspired Engineering of Harvard University and the Simons Center for Geometry and Physics at Stony Brook University.^[4] He designed the Hoberman Arch as a centerpiece of Salt Lake City during the 2002 Olympics. It was later moved to Olympic Cauldron Park and then to the Salt Lake City airport.

In July 2011, the rock band U2 concluded a nearly three-year world-wide concert tour (called "360°") that featured Hoberman's expanding video screen, a 3,800 square feet (350 m²) elliptical display that would grow into a seven-story cone. The display weighed 120,000 pounds (54,000 kg), and incorporated 888 LED screens displaying a total of 500,000 pixels. The complex apparatus was successfully transported and reassembled for 110 concerts during that time.^[4]

In addition to toys such as the Hoberman sphere, Hoberman created the "Brain Twist", a hard plastic tetrahedron that folds, stellates, and becomes self-dual while having a component that rotates similarly to a Rubik's Cube. Likewise, Hoberman's "Pocket Flight Ring" is a folding, throwable toy resembling a chakram.^[5] Hoberman has also created the Expandagon Construction System, a kind of construction toy,^[6] and the Switch Pitch, a toy which turns itself inside out when tossed into the air, thus appearing to change colors.^[7]

In 1994, the Museum of Modern Art added the Hoberman sphere into its permanent collection.^[8] Hoberman won the Chrysler Design Award for Innovation and Design in 1997 and was a finalist for the 2000 Smithsonian National Design Award. He shared the LDI2009 Award for Excellence in Video Design and Technology for the U2360 expanding video screen.^[9]

In 2016, he was appointed the Pierce Anderson Lecturer in Design Engineering at Harvard University.^[10] In 2018, he received an honorary Doctor of Fine Arts degree from the Fashion Institute of Technology.^[11]

In 1990, he formed Hoberman Associates. In 1995, he co-founded Hoberman Designs with his wife and business partner, Carolyn Hoberman.
