Things changed Thursday when shares of Amazon rose more than 1% driving Bezos’ net worth to $90.9 billion, compared to Gates’ $90.7 billion.

When Bezos graduated from Palmetto in 1982, he was not only valedictorian, but also a National Merit Scholar and a Silver Knight award winner for science.

He told The Miami Herald back then he wanted to “build space hotels, amusement parks, yachts and colonies for two or three million people orbiting around the earth.”
