Answer:
Galileo Galilei The Law of the Pendulum
Believe it or not Galileo Galilei was the first scientist to observe how long it took any object suspended from a rope or chain (a pendulum) to swing back and forth. There were no wrist watches at that time, so Galileo used his own pulse as a time measurement.
