Félix d'Hérelle  Félix d'Hérelle (25 April 1873 – 22 February 1949) was a French-Canadian microbiologist. He was co-discoverer of bacteriophages (viruses that infect bacteria) and experimented with the possibility of phage therapy. D'Herelle has also been credited for his contributions to the larger concept of applied microbiology. Hubert Augustin Félix Haerens  His father was 30 years old when he died. At that time, Félix was 6 years old. From 7 to 17 years of age, d'Hérelle attended school in Paris, including the Lycée Condorcet and Lycée Louis-le-Grand high schools. In the fall of 1891, d'Hérelle traveled to Bonn, Germany where he attended lectures at the University of Bonn "for several months." Thus, d'Hérelle obtained only a high school education and was self-taught in the sciences. Between 16 and 24, d'Hérelle traveled extensively via money given by his mother. At 16, he started to travel through western Europe by bike. At 17, after finishing school, he traveled through South America. Afterwards, he continued his travels through Europe, including Turkey, where he, at 20, met his wife, Marie Caire. At 24, now the father of a daughter, d'Hérelle and his family moved to Canada. He built a home laboratory and studied microbiology from books and his own experiments. Through the influence of a friend of his late father, he earned a commission from the Canadian government to study the fermentation and distillation of maple syrup to schnapps. His father's friend shrewdly pointed out that Pasteur "made a good beginning by studying fermentations, so it might be interesting to you, too." He also worked as a medic for a geological expedition, even though he had no medical degree or real experience. Together with his brother, he invested almost all his money in a chocolate factory, which soon went bankrupt. During this period, d'Herelle published his first scientific paper, "De la formation du carbone par les végétaux" in the May 1901 issue of "Le Naturaliste Canadien". The paper is noteworthy for two reasons: it both shows an exceptional level of scientific development for a self-taught scientist and reveals a broad level of interest, namely the global balance of carbon in nature.
