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.
