    Since Galileo began using a rudimentary compound microscope in 1609, whole new ranges of objects not known to even exist were discovered from that basic piece of technology. The microscope played the key role in discovering cells, and as it advanced with technology, so too did the cell theory. In 1665, scientist Robert Hooke used a microscope to look at slices of cork. He noticed that the cork was divided up into hundreds of tiny little compartments that he named cells. Hooke was the first...
