Not all inventors fit the image of the white-haired, bespectacled eccentric scribbling out notes while surrounded by beeping machines and steaming beakers. Some are gorgeous actors or gifted musicians who achieve fame and fortune in their chosen fields, yet still are motivated to fulfill a need or solve a problem afflicting the public. Here are six such celebrities who found the time between photo shoots, interviews, and the demands of their day jobs to follow their personal passions to the patent office.
Marlon Brando
He may not have originated the "method acting" technique, but Marlon Brando was an innovator when it came to his enthusiasm for drumming. Late in life, the Oscar winner devoted his energy to developing a conga drum that could be tuned by way of a single lever at the bottom, as opposed to the usual five or six bolts along the top. Although he received four patents prior to his death in 2004, Brando likely needed to put in more work to make his creation a reality; one drum manufacturer interviewed for a 2011 NPR article indicated that the actor's design was practical, but not cost-effective enough for production.
Hedy Lamarr
During her Hollywood heyday, Hedy Lamarr was known as "the most beautiful woman in the world," a designation that ignored the impressive brain power behind those green eyes. Determined to aid the Allied cause during World War II, Lamarr teamed with composer George Antheil to devise a radio transmission technique that defied enemy disruption efforts by randomly jumping to different frequencies. Although it was initially dismissed by the U.S. Navy, the secret communication system is now recognized as a precursor to the wireless technology that fills our everyday lives. Lamarr also dabbled in more mundane creations, like an improved stoplight and dog collar, and was inducted into the National Inventors Hall of Fame in 2014.
Eddie Van Halen
While he is rightly celebrated for dazzling solos for his namesake band, Eddie Van Halen was also a craftsman who constantly sought out ways to improve the guitar-playing experience for himself and others. In 1987, the rocker patented his musical instrument support, a plate that props up a guitar against the player's body and frees the hands to "explore the musical instrument as never before." Van Halen also acquired patents for a tension adjustment mechanism for stringed instruments, the design and implementation of a noise-canceling humbucking pickup, and a guitar peghead.
Zeppo Marx
The youngest of the Marx Brothers, Herbert "Zeppo" Marx was largely overshadowed as the straight man of the comedic quartet, but he later came into his own as an agent, businessman, and health-minded inventor. His first patent was for a vapor delivery pad for distributing moist heat, intended to replace the inefficient method of dipping towels in hot water to apply to achy body parts. The erstwhile entertainer later received multiple patents related to cardiac monitoring applications, one of which made headlines as the pulse-tracking "heart wristwatch."
Jamie Lee Curtis
While she'd already achieved stardom by way of roles in films such as Halloween (1978) and Trading Places (1983), Jamie Lee Curtis showed she was just as burdened as the next parent when she patented a new and improved diaper in the late 1980s. The solution was a simple one, as her infant garment came with a front pocket for wipes to eliminate the need to hunt down both items during stressful moments. Although she let the patent expire because of concerns over the product's biodegradability, Curtis continued her pursuit of the perfect diaper with another patent in 2017, this time including a plastic bag to make disposal even more tidy.
Bill Nye
Best known as the "Science Guy" from his popular 1990s PBS show, Bill Nye has engaged in a wide-ranging career that includes stints as a mechanical engineer, a stand-up comic and yes, an inventor. As befitting his brainy reputation, Nye designed a noise-and-vibration-reducing device called a hydraulic pressure resonance suppressor for use on the Boeing 747 jumbo jet, and he later received patents for his educational lens and digital abacus. More surprising are his patents for a throwing technique trainer, to help budding baseball players, and his toe shoe, to provide additional support for the grueling regimen of a ballerina.
