Ruska, along with his collaborator Knoll, built the first electron microscope in 1931. It was a transmission electron microscope that revolutionized the field of microscopy by allowing scientists to visualize objects at nanometer scales.
The microscope was first discovered by Dutch spectacle makers Zacharias Janssen and his father Hans in the late 16th century. They developed an early version of the compound microscope using lenses in a tube.
Robert Hooke built the first primitive microscope in the 17th century, enabling him to observe biological specimens like cork. He coined the term "cell" when he observed small box-like structures in the cork, likening them to the cells of a monastery.
