[PAR] [TLE] Rømer's determination of the speed of light [SEP] Rømer's determination of the speed of light was the demonstration in 1676 that light has a finite speed, and so does not travel instantaneously.  The discovery is usually attributed to Danish astronomer Ole Rømer (1644–1710), who was working at the Royal Observatory in Paris at the time.
