NASA Engineer, Super Soaker Inventor & Entrepreneur
Born October 6, 1949
🇺🇸 United States Consumer & Personal ProductsLonnie George Johnson was born on October 6, 1949, in Mobile, Alabama, during the segregation era. Growing up in the Deep South, young Lonnie faced the dual challenges of poverty and systemic racism. However, his parents emphasized education and encouraged his natural curiosity about how things worked. From his earliest years, Lonnie was fascinated by science and engineering, taking apart household appliances to understand their mechanisms and building his own creations.
In high school, Johnson's exceptional talent became undeniable. He built a robot named "Linex" from scrap materials including junkyard parts and reel-to-reel tape recorder components. The robot was so impressive that Johnson won first place at the 1968 Alabama Science Fair—a remarkable achievement for a Black student from a segregated school competing against white students from better-funded institutions. This victory foreshadowed a career defined by breaking barriers.
Johnson attended Tuskegee University on a math scholarship, the historically Black college where Booker T. Washington had recruited George Washington Carver decades earlier. At Tuskegee, Johnson excelled, earning a Bachelor's degree in Mechanical Engineering in 1973 and a Master's degree in Nuclear Engineering in 1975. His education provided the technical foundation for a career that would span aerospace, nuclear technology, and consumer products.
After graduation, Johnson joined the U.S. Air Force, serving as a nuclear engineer at the Air Force Weapons Laboratory. He then worked at NASA's Jet Propulsion Laboratory (JPL) from 1979 to 1982 and again from 1984 to 1987. During these periods, Johnson worked on some of the most advanced aerospace projects of the era.
At NASA, Johnson contributed to the Galileo mission to Jupiter, which launched in 1989 and provided revolutionary data about the gas giant and its moons. He also worked on power systems for spacecraft and helped develop technologies for the Stealth Bomber program—the B-2 Spirit strategic bomber that represented the cutting edge of military aviation technology.
Johnson's work required solving complex engineering problems involving thermodynamics, power systems, and advanced materials. These were high-stakes projects where failure could mean mission failure or, in military applications, strategic vulnerability. Johnson proved himself among the elite engineers working on America's most advanced technologies.
In 1982, while working at JPL, Johnson was experimenting at home with a new type of heat pump that used water instead of Freon. While testing a prototype in his bathroom, he attached a nozzle to a tube connected to his bathroom sink. When he turned on the water, a powerful stream shot across the bathroom. In that moment, Johnson realized he had accidentally created the mechanism for a superior water gun.
Most people would have dismissed this as an amusing accident. But Johnson recognized potential. Water guns existed, but they were weak, requiring constant refilling, and provided limited satisfaction. His pressurized system could shoot water with unprecedented power and range. He began developing the concept in his spare time while continuing his NASA work.
Johnson spent years refining his invention. He built prototypes, tested different pressure systems, and improved the design. He patented the technology in 1986 and 1989. However, manufacturing and marketing a toy required expertise and resources Johnson didn't have. He needed a partner.
After being rejected by several major toy companies, Johnson demonstrated his invention at the 1989 American International Toy Fair. Executives from Larami Corporation, a smaller Philadelphia-based toy company, were intrigued. They saw the potential immediately. Larami licensed Johnson's invention and began manufacturing the "Super Soaker."
The Super Soaker launched in 1990 and became an instant sensation. By 1991, it was the bestselling toy in America. Children—and adults—loved the powerful stream, the futuristic design, and the competitive advantage it provided in water fights. The Super Soaker wasn't just better than other water guns; it redefined the category.
Sales exploded. Between 1991 and 2001, Super Soakers generated over $200 million in sales. Over its lifetime, the product line has generated over $1 billion in revenue. Johnson earned substantial royalties, making him a multi-millionaire and one of the most financially successful Black inventors in American history.
The Super Soaker's success went beyond commercial achievement. It became a cultural icon of the 1990s, featured in movies, TV shows, and music videos. It spawned numerous variations and competitors, creating an entire category of high-performance water toys. Johnson had transformed a bathroom experiment into a global phenomenon.
Johnson didn't rest on Super Soaker success. He founded Johnson Research & Development Co., Inc., and has continued inventing across multiple fields. He holds over 100 patents in areas including thermodynamics, battery technology, and energy systems. His current work focuses on advanced battery technologies and solar energy conversion systems that could revolutionize renewable energy.
Johnson's Johnson Thermoelectric Energy Converter (JTEC) represents potentially breakthrough technology for converting heat directly into electricity with unprecedented efficiency. His Johnson Electro-Mechanical Battery (Johnson EM Battery) could provide energy storage solutions superior to current lithium-ion batteries. While these technologies are still being developed, they demonstrate Johnson's continued commitment to solving important technical problems.
Now in his seventies, Johnson remains active in research and development. He has received numerous honors, including induction into the National Inventors Hall of Fame and the AAAS Philip Hauge Abelson Award. He advocates for STEM education, particularly encouraging young Black Americans to pursue engineering and science careers. His story proves that innovation can come from unexpected places and that success requires both technical brilliance and entrepreneurial perseverance.
From NASA spacecraft to backyard water battles, Johnson's innovations span the spectrum from serious aerospace engineering to cultural phenomenon toys, demonstrating versatility and brilliance.
Lonnie Johnson represents the modern American success story—a brilliant engineer who excelled at the highest levels of aerospace technology while simultaneously creating a billion-dollar consumer product that brought joy to millions. His career demonstrates that innovation doesn't require choosing between "serious" science and commercial success; the same creativity and technical skill can excel in both arenas.
Johnson's story is particularly inspiring for young African Americans pursuing STEM careers. He grew up during segregation in Alabama, faced systemic barriers to education and opportunity, yet became a NASA engineer working on spacecraft missions to Jupiter and cutting-edge military technology. He proved that talent and determination can overcome even the most daunting obstacles.
The Super Soaker's success also illustrates the value of observation and opportunism in innovation. Johnson didn't set out to invent a water gun—he was working on heat pump technology when he accidentally discovered the pressurized water mechanism. But he recognized potential where others might have seen merely an interesting accident. He then spent years perfecting the invention and finding the right partner to bring it to market, demonstrating that innovation requires persistence as much as inspiration.
Today, Johnson continues working on potentially world-changing technologies in energy storage and conversion. If his advanced battery or solar conversion technologies succeed, their impact could dwarf even the Super Soaker's success. At an age when many would be retired, Johnson remains dedicated to solving important technical problems that could help address climate change and energy security. His career exemplifies lifelong commitment to innovation and using technical skills to serve both commercial and social needs.
