Quick Answer. Physicist Ernst Ruska and German engineer Max Knoll are credited with creating the first electron microscope in 1932. It permitted researchers greater magnification and resolution than traditional light microscopes.
There is a lot of controversy regarding the inventor of compound microscope. Though, there are three contenders-Hans Lippershey, Zacharias Jansen-Hans Janssen and Giovanni Faber who coined the name 'Microscope' for Galileo Galilei's compound microscope in 1625. Galileo used to call it the 'Occhiolino' or 'Little eye'. However, Zacharias Jansen and Hans Janssen are widely regarded as the inventors of compound microscope. Zacharias Jansen was a Dutch spectacle-maker from Middelburg. He is also known as Zacharias Janssen and Sacharias Jansen. During 1590-1595, zaccharias janssen and his son hans, while experimenting with several lenses in a tube, discovered that nearby objects appeared greatly enlarged.
