Who invented the chronograph?

The invention of the chronograph is attributed to Louis Moinet, a French watchmaker who created the first chronograph in 1816. Moinet's chronograph was designed to measure astronomical events and it was called a "compteur de tierces" or third counter.

However, the first commercial chronograph was produced by Nicolas Rieussec in 1821, who was also a French watchmaker. Rieussec was commissioned by King Louis XVIII to create a device that could accurately measure the time taken by horse races. Rieussec's chronograph used inked pens that marked the dial to record the elapsed time.
