George Rhoads (January 27, 1926 – July 9, 2021) was a contemporary American painter, sculptor and origami master. He was best known for his whimsical audiokinetic sculptures in airports, science museums, shopping malls, children's hospitals, and other public places throughout the world.

Rhoads was born in Evanston, Illinois, the oldest of four children. His father, Paul S. Rhoads, was a physician and professor of internal medicine at Northwestern University. His mother, Hester Chapin Rhoads, was trained as an interior decorator.

Rhoads attended the University of Chicago with the goal of studying physics and mathematics. After earning enough credits to complete his associate degree, he began taking design and drawing classes at the Art Institute in Chicago. Two years, later he left Chicago and moved to New York City to become a painter. His work focused on portraits and impressionistic cityscapes, but he was not critically or financially successful.

In 1952, Rhoads moved to Paris to continue painting. It was there that he met the American origami expert Gershon Legman who introduced him to the art of origami and the work of Akira Yoshizawa. This meeting sparked Rhoads' interest and he began practicing origami and inventing new folds. His most notable contribution to the field became known as the Blintzed Bird Base, now a standard origami fold used for creating an animal with four legs, two ears and a tail from a single sheet of paper.

Rhoads created his first rolling ball machine in the late 1950s.

In the 1960s, Rhoads began experimenting with kinetic sound-producing metal sculptures. As he described these early machines, "You have a whole range of things happening in succession. Little balls rolling down a track are the motive power that hits a hammer that hits a xylophone bar or blows a whistle." After seeing an exhibit of Rhoads' ball machines in Greenwich Village, the sculptor Hans Van de Bovenkamp hired him to invent devices to use in his metal fountains. Eventually, Rhoads began creating fountains of his own.

Rhoads continued to develop his audio-kinetic sculptures and his work gained national prominence after being shown on The David Frost Show and Today. In the early 1970s, the shopping mall magnate David Bermant commissioned him to build audiokinetic sculptures for his shopping centers in Rochester, New York, and Hamden, Connecticut, and for years afterward continued to promote and sell Rhoads' work.

Rhoads' sculptures became known for their precise clockwork-like mechanisms governed by weight and timing while still maintaining the appearance of spontaneity and randomness. He promoted the concept that the machine itself was a work of art, and his pieces were designed to demystify machinery and stimulate viewer reaction. Modernist sculptor and Professor Emeritus at Princeton University, James Seawright, said of Rhoads' sculptures: "they embody almost every basic element of machinery, combined in a bewildering variety of ways. There's a level of mechanical genius behind inventing complex mechanisms."
