Who is known as the "Father of Bacteriology"?

The title of the "Father of Bacteriology" is attributed to Louis Pasteur. He made groundbreaking contributions to our understanding of microorganisms and their role in fermentation and disease. Pasteur's development of the germ theory of disease fundamentally changed the scientific approach to public health and hygiene practices. He is well-known for inventing the process of pasteurization, which kills harmful bacteria in food and drinks, showcasing his impact on both bacteriology and food safety.

While other figures in the options have made significant contributions to microbiology and related fields, it is Pasteur's work that specifically laid the groundwork for modern bacteriology. Robert Koch, for instance, is renowned for his postulates that provided a clear method to establish the pathogenicity of microorganisms, while Anthony Van Leeuwenhoek is often called the "Father of Microbiology" for his early microscopic observations of bacteria. Edward Jenner is recognized for developing the smallpox vaccine, which is a landmark in immunology rather than bacteriology. Each of these individuals has a distinct role in the development of life sciences, but it is Louis Pasteur who most directly earned the title in question.
