Since Jansen was very young at that time, it's possible that his father Hans made the first one, but young Jansen perfected the production. The work of the French scientist Louis Pasteur shows how an understanding of cell theory can have practical uses. Pasteur lived in the 1800s, when there was no mechanical refrigeration in homes. People were used to having foods spoil, like milk going sour.During this time, many people died from diseases such as typhoid fever, tuberculosis, and diphtheria.

Scientists use the term “theory” to indicate something that is more than just a hypothesis. A theory is a statement that has been proven true after many experiments. The cell theory was Zacharias Janssen contributed to cell theory with the invention of the single-lens microscope and that of multiple lenses for cell discovery. He was able to develop this invention due to his knowledge of the family lineage of lens manufacturers. In respect to this, when did Zacharias Janssen invent the microscope? 1590 .
He observed the formation of yeast and concluded that fermentation of sugar and starch was the result of life processes. He was the first to contribute to the germ theory.
