Anton van Leeuwenhoek, born in 1632 in the Netherlands, was a successful businessman and scientist who improved the microscope and discovered single-celled organisms. He built over 500 microscopes and is considered the father of microbiology.
Anton Thonius Philips van Leeuwenhoek was born in Delft, the Netherlands on October 24, 1632. The son of a craftsman, he took an early interest in biology. When he apprenticed to a cloth merchant, he discovered microscopes. At the time, they were used almost exclusively by fabric makers to see details in fabrics, but van Leeuwenhoek quickly saw the potential for other uses.
Van Leeuwenhoek went on to become a successful businessman. When he was still a college student, he already owned the largest drapery company in the city. In 1669 he graduated as a geographer and started working as a scientist almost immediately. This gave him an opportunity to reconnect with his fascination with microscopes. He began work on an improved version of the original microscope, as well as creating a set of lenses and recording microscopic observations.
In 1676, van Leeuwenhoek was the first to observe single-celled organisms, such as bacteria and sperm, using a microscope he designed. The discovery was initially met with skepticism, but was eventually recognized by England’s Royal Society, leading to his appointment as a Fellow of the Royal Society, the highest scientific award at the time. Over the next 50 years, van Leeuwenhoek maintained a close relationship with the Society, providing a large number of original specimens and notes to the permanent collection. Since he couldn’t draw, he hired an illustrator to provide accurate illustrations.
Van Leeuwenhoek built over 500 microscopes during his lifetime, ten of which have survived to this day. These original microscopes were little more than magnifying glasses mounted on a brass plate. Though primitive by modern standards, he’s microscopes were a vast improvement over earlier designs. They could magnify over 180 times, nearly five times more than any other model available at the time. Van Leeuwenhoek is considered “the father of microbiology” and Charles Darwin elaborated the theory of evolution on the basis of his observations.
