Felix d'Hérelle
Felix d'Hérelle was a French-Canadian scientist who discovered bacteriophages—viruses that infect and kill bacteria—in the early 20th century. His work revealed that these viruses could be used to combat bacterial infections, offering a potential alternative to antibiotics. D'Hérelle's discovery was groundbreaking, paving the way for phage therapy, which aims to target specific bacterial pathogens without harming the patient's cells. His research significantly contributed to microbiology and the ongoing search for effective treatments against bacterial diseases.
