Early Modern. Antonie van Leeuwenhoek is considered a father of microbiology as he pioneered the use of simple single-lensed microscopes of his own design. In 1676, Anton van Leeuwenhoek, who lived most of his life in Delft, Holland, observed bacteria and other microorganisms using a single-lens microscope of his own design.
A microbiologist is a scientist who studies microscopic organisms including bacteria, algae, and fungi. Often, they study organisms that cause disease and environmental damage or are of industrial or agricultural interest. They also study the characteristics of nonliving pathogens, such as viruses and prions.
