Ferdinand Cohn

Ferdinand Cohn was a pioneering microbiologist and biologist from Germany who lived in the 19th century. He made significant contributions to the study of bacteria, helping to identify and classify different types of microorganisms. Cohn was among the first to describe bacterial shapes, such as rods and spirals, and developed methods to grow bacteria in the laboratory. His work laid the foundation for modern microbiology, influencing how scientists understand germs, diseases, and sterilization, ultimately advancing medicine and biology.
