For five years he worked on the silkworm diseases and eventually found the problem. The silk industry was saved, and Pasteur’s reputation grew. Once discovering the bacteria that cause cholera, a deadly disease at the time, he discovered how to make a good vaccine. New discoveries about photography were happening during the 1860’s. English physician and physicist Thomas Young had a theory regarding color vision. Young believed that the eye had three types of receptors that were sensitive to three primary colors of light. Maxwell showed how any color of the rainbow could be created by adding or subtracting one of these three primary colors of light: red, blue, and green. Using this knowledge, he made the first color photograph in 1861. Later he went on to study the nature of Saturn’s rings. The astronomer and physicist Christiaan Huygens who discovered them, had a theory that was not yet
