Biography Of Antonie Philips van Leeuwenhoek


Antonie Philips van Leeuwenhoek (1632-1723), was a Dutch chemist who is credited with the development of microbiology. He was a businessman and invented his revolutionary microscopes. This technological breakthrough enabled him to make innumerable discoveries about the world that could only be seen through microscopes. He revolutionized science’s view of the living world by discovering single-celled organisms and bacteria. He was a self-taught scientist and was often criticized for not having a scientific background. He shared his findings with the Royal Society and they were widely accepted. This led to a new science, microbiology.

Antonie van Leeuwenhoek, a Dutch Republic citizen, was born in Delft on 24 October 1632. He was just four days after Johannes Vermeer, the well-known artist who was also from Delft. After receiving a basic education in 1648 van Leeuwenhoek was made an apprentice in an Amsterdam draper’s shop where he stayed for six more years.

He married Barbara de Mey in 1654 and returned to Delft. He borrowed 5,000 florins to buy the house and shop Het Gouden Hoofd. Here he established his own draper’s business and gained a lucrative job as a camerbewaarder for the Delft sheriffs. Later, he was appointed official wine-gauger of Delft’s wines imports and taxes.

The first marriage was a tragedy. They had five children but only Maria survived childhood. Barbara, his wife, died 12 years after their marriage. He remarried Cornelia Swalmius in 1671, but they did not have any children.

He wanted to be able to see the cloth fibers better in Draper’s workshop. After feeling that the current lenses were not adequate, he set out to create stronger lenses. He discovered that he could make a small but powerful lens by heating a piece of soda lime glass. This was a significant technological breakthrough that made Van Leeuwenhoek’s microscopes more powerful than any other in existence. Van Leeuwenhoek kept his secret method secret because it allowed him to have exclusive access to the new biology of tiny magnification. He would conceal his powerful lenses in his rooms and pretend that he had made them using the traditional grinding method. He made more than 500 optical lenses over his lifetime and 25 single-lens microscopes. Because each object of research required its lens, he made many. Some lenses survived, and some were capable of magnifications up to 275 times. This was quite remarkable for this age. He took his secret to lens magnification to his grave. Van Leeuwenhoek was the first to discover how to fuse glass thread independently.


He used his microscopes to study many aspects of nature, including blood, skin, and blood, in his spare time. He was not a scientist, but a businessman. In London, he started to correspond with the Royal Society. Constantijn Huygens, a physician who wrote about Van Leeuwenhoek, introduced him to Robert Hooke and the Royal Society.

“[He] is a modest man, not learned in languages or sciences, but of his nature exceedingly industrious and curious… always humbly submitting his experiences to the censures and corrections of the learned.”

They were enthusiastic about Van Leeuwenhoek’s breakthrough discoveries, which encouraged Van Leeuwenhoek to continue his research and send his findings to The Royal Society.

Van Leeuwenhoek was an ‘amateur’ scientist who worked meticulously for many years. His dedication and meticulousness enabled him to make remarkable discoveries. They were not based on any new trends or developments. These discoveries were revolutionary in scientific terms. Van Leeuwenhoek was, for example, the first person to discover single-celled organisms (like the amoeba). The discovery was so surprising that the Royal Society had difficulty believing it. Van Leeuwenhoek prefers to work alone and only writes in Dutch. He has never published a paper in Latin. There was some skepticism about his results, despite there being interesting. Six observers were sent by the Royal Society to see van Leeuwenhoek’s work to verify their reliability. The Royal Society was able to accept these discoveries, which had implications for scientific understanding. Van Leeuwenhoek, who was a surprise to many, was elected to the Royal Society in 1680.

Van Leeuwenhoek was a Calvinist Protestant Christian. His work on the beauty, majesty, and power of the small was a confirmation of God’s power and grace.

“Once again we see the unimaginable Providence, perfection, and order bestowed upon such small creatures by the Lord Creator of the Universe, so that their species shouldn’t perish.”

He discovered many amazing things about bacteria and cells and postulated that there were billions, if not trillions of people and water. He defended his claims based on careful observation when his seemingly absurd claims were challenged. Galileo’s work was well-known to him and the way the notion that the earth revolved around the sun was resisted for a long period.

“Whereas there are many contradictions and I often hear it said that my only purpose is to tell fairy tales about little animals and that there are people from France who don’t hesitate to claim that they aren’t living creatures that I exhibit,… I boldly say, that those who say such things haven’t yet advanced enough to be able to make good observations.” – Van Leeuwenhoek to Robert Hooke, November 12, 1680

Van Leeuwenhoek was convinced by his discoveries of microorganisms that the theory of spontaneously generating lower life forms is wrong. Van Leeuwenhoek proved that fleas can be created through reproduction, just as larger organisms. Van Leeuwenhoek stated that he was driven by a desire to learn. He wrote a letter dated June 12, 1716.

“My long-standing work was not done to earn the praise I now receive, but because I had a deep desire for knowledge. I find that I have more of it than most men.”

Although he was an amateur scientist, his observations and experiments were based on scientific principles such as observation, repeatable experiments, and sharing findings with peers to critique. Van Leeuwenhoek was in many ways ahead of his time. His initial discoveries on bacteria and protozoa would take nearly two centuries to be accepted into germ theory. This was thanks to the work of Louis Pasteur and Joseph Lister.

Van Leeuwenhoek’s contributions were crucial in opening up the microbiology world with all its potential to understand the world. Among his most important observations and discoveries were:

Infusoria is a tiny aquatic creation such as ciliates and euglenoids.
The vacuole (storage area in cells) is the cell’s vacuole.
Red blood cells and white blood cells.
The structure of muscle fibers
Van Leeuwenhoek was alive for 90 years which is quite rare in the seventeenth century. He was visited by many notable people in his later years, including Peter the Great and the Queen of England. He was a major contributor to the advancement of modern science. He is both a figure of the late Scientific Renaissance as well as the modern Age of Enlightenment.
