Today, Mike Bezos is the father of the richest man in the world, Jeff Bezos. But in 1962, Mike Bezos came to America from Cuba wearing a jacket his mother had hand-stitched from cleaning rags. He was a teenager traveling by himself and he spoke almost no English.

"When he came here from Cuba at 16, not only was he all alone, but he only spoke Spanish. His grit, determination, and optimism are inspiring," Bezos tweeted about his father Wednesday.
