Marius was a German astronomer who was one of the first to use a telescope. He had a dispute with Galileo for priority of the discovery of Jupiter's four largest moons. He did not receive the credit, but his names: Io, Europa, Calisto, and Ganymede are still used today. He also recorded observations of the 'nebula' Andromeda noting it got brighter in the center than the edges. Today, we know Andromeda is a nearby galaxy.
