Olaus Roemer
Olaus Roemer discovered the finite speed of light in the late 17th century. He observed that the time it took for light to travel from Jupiter to Earth varied as the distance between the two planets changed, leading him to calculate a rough estimate of the speed of light. This discovery laid the foundation for later, more precise measurements of the speed of light.
It was the Danish astronomer, Olaus Roemer, who, in 1676, first successfully measured the speed of light. His method was based on observations of the eclipses of the moons of Jupiter (by Jupiter).
