Anton van leeuwenhoek why is he important

For example, by examining the plaque on his teeth, he said that the microorganisms in his mouth outnumbered the people in the Netherlands. Rather, he was viewed as an eccentric magician who was always talking about imaginary creatures.

But his work was not overlooked by men of science. At that time, the Royal Society of London, which was chartered by the King, had a corresponding member in Delft. Although he was initially met with skepticism, he was finally believed by the Royal Society and became a full fellow of the Royal Society in For the next 50 years, he wrote hundreds of letters to the society, and they were published in newspapers.

He attracted attention to such tiny things as bacteria, microbes, and cells. Antonie van Leeuwenhoek changed the world by introducing the science of microbiology. He discovered bacteria and microbes as the smallest living things that had great impacts on human life.

The first bacteria were discovered by Antonie van Leeuwenhoek. He was trying to find out why pepper is spicy by keeping pepper in water for three weeks. Instead, he found little living things in motion that were later called bacteria. Antonie van Leeuwenhoek is famous because he created a major turning point in the course of science. He introduced microbiology and discovered bacteria. By Vejas Liulevicius P. This paradigm shift is often referred to as the Scientific Revolution.

In , van Leeuwenhoek observed water closely and was surprised to see tiny organisms - the first bacteria observed by man. His letter announcing this discovery caused widespread doubt at the Royal Society but Robert Hooke later repeated the experiment and was able to confirm his discoveries.

As well as being the father of microbiology, van Leeuwenhoek laid the foundations of plant anatomy and became an expert on animal reproduction. He discovered blood cells and microscopic nematodes, and studied the structure of wood and crystals.

He also made over microscopes to view specific objects. He also discovered sperm, which he considered one of the most important discoveries of his career, and described the spermatozoa from molluscs, fish, amphibians, birds and mammals, coming to the novel conclusion that fertilisation occurred when the spermatozoa penetrated the egg.

The word "bacteria" didn't exist yet, so he called these microscopic living organisms "animalcules. Leeuwenhoek's first report to the Royal Society in described bee mouthparts, a louse, and a fungus. He studied the structure of plant cells and crystals, and the structure of human cells such as blood, muscle, skin, teeth, and hair. He even scraped the plaque from between his teeth to observe the bacteria there, which, Leeuwenhoek discovered, died after drinking coffee.

He was the first to describe sperm and postulated that conception occurred when a sperm joined with an ovum, though his thought was that the ovum just served to feed the sperm. At the time, there were various theories of how babies formed, so Leeuwenhoek's studies of sperm and ovum of various species caused an uproar in the scientific community. It would be around years before scientists would agree on the process.

Like his contemporary Robert Hooke , Leeuwenhoek made some of the most important discoveries of early microscopy. In one letter from , he wrote,. He did not editorialize on meanings of his observations and acknowledged he was not a scientist but merely an observer. Leeuwenhoek was not an artist either, but he worked with one on the drawings he submitted in his letters. Van Leeuwenhoek also contributed to science in one other way.

In the final year of his life, he described the disease that took his life. Van Leeuwenhoek suffered from uncontrollable contractions of the diaphram, a condition now known as Van Leeuwenhoek disease. He died of the disease, also called diaphragmatic flutter, on August 30, , in Delft.

Some of Leeuwenhoek's discoveries could be verified at the time by other scientists, but some discoveries could not because his lenses were so superior to others' microscopes and equipment. Some people had to come to him to see his work in person. Just 11 of Leeuwenhoek's microscopes exist today.

His instruments were made of gold and silver, and most were sold by his family after he died in Other scientists did not use his microscopes, as they were difficult to learn to use.

Some improvements to the device occurred in the s, but big improvements that led to today's compound microscopes didn't happen until the middle of the 19th century.
