Benjamin Banneker was born November 9, 1731. He was a free African American astronomer, mathematician, surveyor, almanac author and farmer. Benjamin Banneker completed the clock in 1753 at the age of 21. Benjamin Banneker's invention affects use because people use clocks to know what time it is in the day. His invention affects me because I use clocks to know what time it is as well.
