Leonard S. Schleifer
$36.3 million

As the President and CEO of Regeneron Pharmaceuticals, Leonard S. Schleifer fought hard to get into the field of biotechnology. Originally, the company was doing research on nervous system diseases after he noticed that most biotechnology companies didn’t focus on neurological medicines. But, transitioned into drugs that assist colorectal cancer, lower cholesterol, and helping blindness in the elderly. In 2013, Schleifer was welcomed to the world of being a billionaire after one of the company’s drug sold successfully.
