8 photos of Donald Trump in high school

Before he was a real-estate mogul, a graduate of the Wharton School of Business at the University of Pennsylvania, or the president of the United States, Donald Trump was an unruly teen whose parents sent him to military school.

Trump's parents sent him to the New York Military Academy when he was 13 because of his acting up.

His father, Fred Trump, hoped "the discipline of the school would channel his energy in a positive manner," according to The Washington Post.

Trump graduated in 1964 and went on to study at the University of Pennsylvania.

Thanks to Classmates.com, we found photos of Trump from his time at the school.

Here are some pictures of Trump that are over a half-century old:

This is Trump's senior picture, from the New York Military Academy's 1964 yearbook.

That year, Trump was voted the "Ladies Man" of his class in a likely tremendous "popularity poll." We're guessing it was the first of many polls Trump would win.

Trump claims he was quite an athlete earlier in life. Here he is as a member of the 1964 New York Military Academy's varsity soccer team.

Soccer wasn't Trump's only athletic forte that year. Here he is with his fellow intramural bowling team staffers, second from the right.

He was also a captain on the varsity baseball team. (He's sitting fourth from the left on the bottom row.) In 1964, Trump's squad went 5-6-1, with the tie coming in the team's final game of the season.
