Leeuwenhoek
Leeuwenhoek is the surname of Antonie van Leeuwenhoek (1632–1723), a Dutch scientist who is best known for his work on the development and improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes, he was the first to observe and describe single-celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa, and blood flow in capillaries (small blood vessels).
Early life[edit | edit source]
Antonie van Leeuwenhoek was born in Delft, the Netherlands, on 24 October 1632. His father was a basket maker, while his mother's family were brewers. Antonie went to school in Warmond, then later in Benthuizen, near Leiden. He left school at 16 to become a bookkeeper's apprentice at a linen-draper's shop in Amsterdam.
Career[edit | edit source]
In 1654, Leeuwenhoek returned to Delft, where he would live and study for the rest of his life. He opened a draper's shop, which was successful and enabled him to pursue his scientific interests. His work in the field of microscopy began after he started examining the quality of the threads in his draper's shop with a magnifying glass.
Contributions to Microbiology[edit | edit source]
Leeuwenhoek made his microscopes by grinding a small lens of high curvature which gave a magnification of about 200 times. These were not compound microscopes, which in his time were, at best, comparable in quality. With these microscopes, he made a number of crucially important scientific discoveries, including the infusoria (in 1674), bacteria (in 1676), and the spermatozoon (in 1677).
Death and Legacy[edit | edit source]
Leeuwenhoek died on 26 August 1723. Over his lifetime, he had written approximately 560 letters to the Royal Society and other scientific institutions concerning his observations and discoveries. Even after his death, Leeuwenhoek's discoveries remained influential in the scientific community, paving the way for future research in microbiology.
