From having his face on every Wheaties box to having his face on the cover of just about every tabloid in America, it’s been a long, strange trip for Bruce Jenner.

His stepdaughter, Kim Kardashian, might be one of the biggest celebrities on the planet today, but back in 1976, Bruce was just as popular. After winning and setting a new world record at the 1976 Summer Olympics, Jenner skyrocketed to fame and has been in the public eye ever since. Three wives, six kids, and four stepchildren later, Bruce has been the epitome of a family man in the past few decades, but he’s currently making headlines for finally focusing on himself.

In the past few years, Jenner has been known as the quirky dad on Keeping Up With The Kardashians, but his upcoming interview with Diane Sawyer won’t have much to do with his famous family. It’s been speculated for many years that Jenner had been hiding something about his gender, but he has just recently decided open up about the subject. For someone who hasn’t had much privacy for most of his life, you may think going public about his supposed gender transition is easy, but as we’ve learned from other celebrities, it’s an extremely personal topic.

In the following video, we take a look back at Bruce when he was the most famous athlete in America and best known for his incredible accomplishments in the Olympics.
