The Story of Louis Pasteur
The Story of Louis Pasteur is a 1936 American black-and-white biographical film from Warner Bros., produced by Henry Blanke, directed by William Dieterle, that stars Josephine Hutchinson, Anita Louise, and Donald Woods, and Paul Muni as the renowned scientist who developed major advances in microbiology, which revolutionized agriculture and medicine. The film's screenplay—which tells a highly fictionalized version of Pasteur’s life—was written by Pierre Collings and Sheridan Gibney, and Edward Chodorov (uncredited).
In Paris in 1860, a distraught man murders his wife's doctor. Chemist Louis Pasteur (Paul Muni) has been publicizing a theory that diseases are caused by microbes, which doctors should avoid spreading by washing their hands and sterilizing their instruments in boiling water. The doctor did not do this and the wife died of puerperal fever after giving birth.
