- from Cells
Around 1590, the Dutch lens makers Hans and Zacharias Janssen hit on an invention that made the discovery of cells inevitable. They put two glass lenses in a tube and created the world’s first microscope.
About 60 years later, English scientist Robert Hooke used the invention to study cork from a tree. He called the empty compartments he saw cells. The name stuck, but our view of them has changed radically.
