No, Benjamin Banneker did not invent the first clock. He was known for his work as a mathematician, astronomer, and surveyor. Banneker is famously known for his wooden clock that he built in the 18th century.
The first striking clock is attributed to the Italian monk and mathematician, Guido of Arezzo, who created a device in the 13th century that struck the hours. This innovation laid the foundation for the development of mechanical clocks.
It was in 1789 which was a very odd time to be born but thats the date for ya :P
