The light microscope was invented around the 1590s by Zaccharias Janssen and his son Hans. It was later improved in 1609 by Galileo.
The father-and-son inventors of the compound microscope were Hans and Sacharias Janssen, Dutch lens makers.However there was a third Dutch lens maker, Hans Lippershey, who independently designed and built an instrument using exactly the same concept at the same time.Generally, these three are severally credited with this invention, ca. 1590.
