Louis Braille Invented The Braille Language For The Blind At 15
Born in France in 1809, Louis Braille was blinded at the age of just 3 years old. Braille didn't let his condition limit what he could do, however.
While a student at the Royal Institute for Blind Youth in 1824, Braille met Charles Barbier, an officer who had developed "sonography," a system of written communication based on raised dots.
Though Barbier had developed his system with the French Army in mind, 15-year-old Braille believed a similar method could be used by people who were blind - and so he went to work creating what is now known as "braille."Does this make you feel old?

When Alexander was 16, his father, Philip II, went away on a military campaign and put the kingdom in Alexander's hands. Alexander marked the occasion by leading the Macedonians to victory against the Thracians and acquiring the first part of what would become a vast empire.Does this make you feel old?
Born in Ohio in 1860, Annie Oakley - perhaps the most mythologized sharpshooters in American history - saw sidearms as a way to support her family. According to Oakley, she first took up a pistol to feed her family. The target was a squirrel. "I was 8 years old when I made my first shot, and I still consider it one of the best shots I ever made," she said.
That first shot would inaugurate a legendary career. Oakley's hunting not only fed her family but also generated an income. She sold some of the game from hunts to area shops for a profit. She made so much money that by the age of 15, Oakley paid off her mother's mortgage.
Oakley's shooting was so good that she entered - and won - competitions as a teenager, and went on to enjoy international fame.Does this make you feel old?
