Jerome Lemelson’s inventive legacy touches nearly every facet of our everyday lives. One of America’s most prolific inventors, he earned more than 600 patents for inventions relating to automated manufacturing systems, bar code readers, automatic teller machines, cordless phones, cassette players, camcorders, fax machines, personal computers, machine vision, and medical technology. What may be surprising, though, is that about 10 percent of those patents describe toys—inflatable toys, jumping toys, toys with propellers, toys that run on tracks, target games, dolls, and more. In fact, Lemelson’s first patent, issued in 1953, was for a new kind of propeller beanie.
One of the most interesting things about Jerry Lemelson’s toy patents is the way in which they parallel interests that he was pursuing in other fields. For example, a number of his inventions incorporate the behavior of fluids (gases and liquids), magnetism, light, and sound. So his version of the propeller beanie (U.S. Patent 2,654,973) didn’t rely on the vagaries of wind, but instead used an attached tube through which the wearer could blow to spin the propeller or sound a whistle. Counterparts on the more serious side included inventions in aircraft structures and materials, and a balloon-actuated catheter.
Similarly, his ideas about sound manifested themselves in a barking, jumping toy dog, a toy gun that makes a ricochet noise, and a crying doll, as well as magnetic sound-recording devices and ultrasonic cleaning devices. The properties of magnetism were at the heart of a toy mine detector, various ways to move toy cars along a track, and a magnetic fishing game, and also of audio and video magnetic recording and reproduction apparatus. Inflatable toys with “eyecatching optical effects,” reflective highway construction markers, lenticular displays, reflective thread to be woven into cloth, and light-sensitive material for contact lenses reflect Lemelson’s examination of the properties of light.

Lemelson’s patents also illustrate an exploration of the use of new materials, especially plastics, for both toys and other objects. There are inventions pertaining to manipulating plastic, including injection molding and extrusion processes. And there are toys and other inventions made of plastic: inflatable toys and envelopes made of sheet plastic; plastic illuminated highway markers; flexible plastic tracks for toy cars; plastic product containers; and plastic kites, gliders, and model airplanes.
The ways in which Lemelson’s curiosity and investigation into processes and materials affected the range of his inventive activity illustrate a trait found in many inventors: they often use analogy to develop their ideas, whether that means seeing how one thing may be like another or applying knowledge from one field to another. So propeller beanies and aircraft wings are not as far apart in the inventor’s imagination as they may seem to us. Jerry Lemelson had the gift of being able to play with ideas and extract many different inventions from each one. As his son Robert noted, “He took the idea of play and transformed it into a lifelong vocation.”
To see examples of Lemelson’s toy inventions that show some of the stages in inventing a new plaything, visit the Toying with Invention display at the Lemelson Center on the third floor of the Museum. And don’t miss the chance to learn about more playful inventors—and connect with your own creative spirit—at the Lemelson Center’s interactive family exhibition, Invention at Play, on the Museum’s first floor.
