Ticktock Banneker's Clock

When Benjamin Banneker was born in Maryland in 1731, he was already an extraordinary person for that time period. He was born free at a time in America when most African Americans were slaves. Though he only briefly attended school, Benjamin displayed a keen aptitude for mathematics and science. Inspired by a pocket watch he had seen, at the age of 22 he built a strike clock based on his own drawings and using a pocket-knife.
