Around 1590, Dutch lens makers Hans and Zacharias Janssen made the first microscope. They did that by putting two glass lenses in a tube. About 60 years later, English scientist Robert Hooke used a similar device to study cork from a tree. He saw what looked like empty compartments in the magnified cork and called them cells.

Zacharias Janssen contributed to cell theory with the invention of the single-lens microscope and that of multiple lenses (compound microscope) for cell discovery in the future. He was able to develop this invention due to his knowledge of the family lineage of lens manufacturers.

This is the biggest contribution to the cell theory because without Hooke cells may not have been discovered for hundreds of more years. 1) Hans and Zacharias Janssen were known for inventing the compound optical microscope. This contributed to the cell theory by making it easier and more practical to observe cells.

Anton Van Leeuwenhoek used the Hans and Zacharias Janssen's microscpe to invent a new type of microscope and so became the first person to see single-celled animals with a microscope.
