The Story of Louis Pasteur

The Story of Louis Pasteur is a 1936 American biographical film. It starred Paul Muni as the renowned scientist who developed major advances in microbiology which revolutionized agriculture and medicine. It was written by Pierre Collings and Sheridan Gibney, and Edward Chodorov uncredited, and directed by William Dieterle.

In nineteenth century chemist Louis Pasteur Paul Muni believes that diseases are caused by unseen microbes. His radical theory is dismissed by most doctors, particularly his most vocal critic, Dr. Charbonnet Fritz Leiber, Sr.. Nonetheless, Pasteur carries on, with the assistance of a small group of loyal researchers, and finds a cure for anthrax. He also campaigns to have doctors wash their hands and sterilize their instruments before operating.Charbonnet is so certain that Pasteur is a quack that he injects himself with some of the rabies virus. When a triumphant Charbonnet shows no sign of contracting rabies, Pasteur is puzzled, until his wife suggests that the sample may have gotten weak with age. This sets him on the right path to finding a cure. When a frantic mother begs him to try his untested treatment on her son Dickie Moore, who has been bitten by a rabid dog, Pasteur risks imprisonment and possibly the guillotine to save the child. Even Charbonnet finally concedes that he is right. In the end, Pasteur is honored for his accomplishments. ........
