Lonnie Johnson is an African American engineer, inventor, and entrepreneur who turned a bathroom accident into one of the best-selling toys of all time. While most people know him as the creator of the Super Soaker water gun, he is also a brilliant aerospace engineer who helped build spacecraft for NASA. His story shows that great inventions can come from the most unexpected places.
Lonnie George Johnson was born on October 6, 1949, in Mobile, Alabama. Even as a young boy, he loved to take things apart and figure out how they worked, and he once built a robot out of scrap metal and parts from old junkyard items. In high school, he entered a science fair with a remote-controlled robot called “Linex,” becoming one of the only African American students to compete. He earned a scholarship to Tuskegee University, where he earned both a bachelor’s degree in mechanical engineering and a master’s degree in nuclear engineering.
After college, Lonnie Johnson went to work for NASA’s Jet Propulsion Laboratory, where he contributed to some of the most important space missions in history. He worked on the Galileo mission, which sent a probe to study Jupiter and its moons, and the Cassini mission to Saturn. He also served as a nuclear engineer in the United States Air Force. Throughout his career at NASA, he continued to tinker and invent things in his spare time, which would soon lead to his most famous creation.
In 1982, Lonnie was experimenting with a new type of heat pump in his bathroom when a powerful blast of water shot across the room. Instead of just mopping up the mess, he realized that the high-pressure water stream would make an incredible toy. He spent years developing a prototype and finally partnered with a toy company to bring it to market in 1990. The Super Soaker became a massive hit, earning over one billion dollars in total sales and becoming one of the top-selling toys of all time.
Lonnie Johnson holds over 80 patents for his inventions, and he has never stopped working on new ideas. He has used the money from his Super Soaker royalties to fund Johnson Research and Development, a company focused on clean energy technology. One of his most exciting projects is developing a new kind of solid-state battery that could make electric cars and solar energy storage much more efficient. From water guns to advanced batteries, Johnson keeps finding new ways to put his engineering skills to work.
