William was the first director of the Harvard College Observatory and he installed the second largest telescope in the world there. William looked at the planet Saturn, sunspots, and the Orion Nebula. William and George thought that Saturn's rings were not solid, but liquid. Later they threw away this theory. George later developed the chronograph to record the stars' positions.
