Photographic reproduction portrait of Pierre Paul Émile Roux (1853-1933), a French physician and assistant to renowned scientist Louis Pasteur (1822-1895) from 1878 until 1883. Roux and French microbiologist, Charles Chamberland (1851-1908) assisted Pasteur in his public experiment to test a method of preventative vaccination for anthrax. The scientists successfully vaccinated sixty sheep, proving the efficacy of the new vaccine. Roux also began his research on the microbiological causation of diseases at this time. He served as the director of the Pasteur Institute from 1904 until 1933. Roux was responsible for the Institute's production of the anti-diphtheria serum, which was the first effective therapy for this disease.
