38. Hakeem Olajuwon - $200m

38. Hakeem Olajuwon - $200m

"The Dream". One half of the Twin Towers. The only player in history to win the NBA MVP, Defensive Player of the Year and Finals MVP awards all inside the same season in the mid-1990s. It's the offensive players who claim all the glory, but Olajuwon was a wall in defense, and when he retired he was the league's all time block leader.

Born Nigerian, Olajuwon adopted American citizenship, which enabled him to play for the USA team in the 1996 Olympics, where he won a gold medal. Proud of his Muslim faith, it was noted that observing the fasting ceremony of Ramadan didn't seem to affect him at all, and indeed in 1995 he was named NBA Player of the Month for February despite observing fasting at the time. Beloved in the city of Houston for his sporting achievements, Olajuwon has built a property empire there, which makes sure his finances stay healthy in his retirement.

When we think of inventors, the image that comes to mind is usually that of a frazzled scientist toiling away in a lab, not celebrities pulled from the pages of Us Weekly. However, a number of well-known public figures hold patents for various innovations. Some are related to the work that made them famous, while others are offshoots of hobbies or just a single great idea.

Part of guitar wizard Eddie Van Halen's signature sound was his two-handed tapping technique, but letting all ten fingers fly while simultaneously holding up the guitar's neck could get a bit tricky. Van Halen came up with a novel way to get around this problem, though; he invented a support (top) that could flip out of the back of his axe's body to raise and stabilize the fretboard so he could tap out searing songs like "Eruption." While Van Halen was obviously interested in improving his guitar work, the patent application he filed in 1985 notes that the device would work with any stringed instrument.

It’s probably not surprising that James Cameron—who designed a submersible to take him to the deepest known part of the ocean—will often invent technology to make his films if what he needs doesn’t exist. He holds a number of patents, including US Patent No. 4996938, “apparatus for propelling a user in an underwater environment,” that he and his brother, Michael, created to film The Abyss and patented in 1989. The device is basically an underwater dolly equipped with propellers that makes it easy for a camera operator to maneuver in the water—and allowed Cameron to capture the shots he wanted for the 1989 film, part of which was filmed in an abandoned nuclear reactor.

In 1987 Jamie Lee Curtis designed and patented a disposable diaper that included a waterproof pocket that held baby wipes. She hasn't profited from her idea yet, though, since she refuses to license the patent until diaper companies make biodegradable products.

You know him as a rock legend, but Neil Young also loves trains—so much that he owns a stake in a model train manufacturing company and has an extensive collection. He also holds seven patents related to model trains, including Patent No. US5441223, "Model train controller using electromagnetic field between track and ground."
