The Story of Louis Pasteur is an episodic telling of the life of Louis Pasteur, a chemist who made great strides in terms of the understanding and prevention of diseases caused by microscopic organisms. The film covers various portions of his career. His time in simply having germs recognized to exist to begin with, then his development of a cure for Anthrax then later a treatment for rabies. William Dieterle is an extremely capable director when it comes to creating atmosphere but he seems shackled here by the straight forward nature of this story. There is only one scene when a man is being treated for Rabies using an archaic method where one can see Dieterle usual ability. It's a completely respectable film fitting to its completely respectable subject matter.
