38. Ben Franklin
- Most Famous For Inventing: Lightning Rod, Flexible Urinary Catheter, Bifocal Glasses
Ben Franklin is one of the world’s greatest inventors, who invented some impressive and useful things we still use. However, one thing often mistakenly attributed to him is that he “discovered electricity.” He didn’t actually do this. However, he did discover how certain objects connected to it.
This allowed him to create the lightning rod, something he realized could be useful after his infamous kite experiment. He also helped to pioneer electrotherapy as well. Beyond this, he invented the flexible urinary catheter. For those who have ever been forced to use one, the modern-day version is thanks to Ben. Of course, he is also well-known for his invention of the Bifocals.
