Who was the person who thought about the idea of using clock?

Answer 1

It depends how you define it. I think methods of tracking time are about as old as the wheel. Are you talking sundials, mechanical clocks, round faced like we use now??

Answer 2

There was a sun dial developed and used by monks long before Christs birth and it was the first clock, and now its where its now.

Answer 3

Must have been someone constantly missing their plane because they were too late at the gate.
