American engineer born in Mobile, Alabama in 1949, who worked on the Galileo and Cassini missions at NASA's Jet Propulsion Laboratory before turning to independent invention. In 1989 he patented the Super Soaker, built around pressurised-air water-gun technology he'd developed while working on a heat pump, which became one of the best-selling toys in history. He holds more than 100 patents and has spent decades of the royalties funding his own research into solid-state batteries and energy conversion.
He built a career at the edge of a field, aerospace engineering, that had very few Black engineers in it, then used the proceeds from a toy most people never connect to that career to keep funding harder, unglamorous energy research most companies wouldn't back. The Super Soaker's success bought him the freedom to keep inventing on his own terms.
No standalone quote from him has been verified for this site yet; his interviews and patent record are the primary sources for now.
