Anton van Leeuwenhoek the Father of Microbiology

anton van leeuwenhoek contribution

He was born in Delft, a city in the province of South Holland in the Netherlands. The original is Greek, and states Omnis cellula e cellula. Credits New World Encyclopedia writers and editors rewrote and completed the Wikipedia article in accordance with New World Encyclopedia. He had no formal training, but with his skill, his diligence, his endless curiosity, and an open mind free of the scientific dogma of his day, he succeeded in making some of the most important discoveries in the history of biology. He developed techniques for constructing lenses of his own, and in his li … fetime made more than 500 microscopes. In 1671, Leeuwenhoek constructed his first simple microscope.

What Were the Scientific Contributions of Antony Van Leeuwenhoek?

anton van leeuwenhoek contribution

Leeuwenhoek used magnifying glasses for inspecting the quality of thread in his draper linen but he was not satisfied with the magnification provided by the available lenses. However, his studies on single celled organisms, sperm cells, and more led to intense criticism, and doubt as it was a new foreign concept. Using his handcrafted microscopes, van Leeuwenhoek was the first to observe and describe single celled organisms that he first referred to as animalcules, and which we now refer to as microorganisms. Through his microscope, Leeuwenhoek examined such substances as skin, hair, and his own blood. The capability of one of his single-lens instruments, far exceeded that of Hook's compound system. Lenses were an important tool in Leeuwenhoek's profession, since cloth merchants often used small lenses to inspect their products.

Anton Van Leeuwenhoek's Cell Theory

anton van leeuwenhoek contribution

His interest in microscopy began with the low-power x3 lenses used for inspecting textiles. They had one lens and a brass plate, and the lens was adjusted by turning two screws. This statement was the first generalized statement about cells. Leeuwenhoek began by examining some snow-water that he had kept sealed for three years. The curve of the lens affects the intensity of magnification, meaning higher magnification needs a greater curve.

Anton van Leeuwenhoek the Father of Microbiology

Starting from the assumption that life and motility are identical, he concluded that the moving objects that he saw through his microscope were little animals.

A Dutch tradesman from Delft, Netherlands, Leeuwenhoek did not pursue a higher education. In his own modest way he realized how rare his gifts were and also that other people's motives were not always those of a true student of nature. Leeuwenhoek followed the Cartesian method in trying to apply his somewhat primitive knowledge of the laws of physics to living nature and thereby exhibited some bias against chemical explanations. However, he never wrote about the method he used to light up his specimens for viewing, and the nature of that lighting technique is still a mystery.

Anton Van Leeuwenhoek: Biography, Cell Theory & Discoveries

Armed with these powerful magnifying devices, he started recording his observations of minute creatures such as molds and lice. Filed Under: Tagged With: Primary Sidebar. Since he considered the flower to be the beautiful but functionless ornament of the plant, Leeuwenhoek did not investigate the anthers and ovaries. In conclusion, microbiologists of the world rely upon the initial findings and inventions of Anton van Leeuwenhoek from several hundred years ago Leeuwenhoek died in 1723 at age 90 and was buried in his hometown of Delft, Netherlands. In 1654, he returned to Delft to establish his own shop, and he worked as a draper for the rest of his life.

Cell Theory Timeline

anton van leeuwenhoek contribution

One of his most ground-breaking discoveries was also one of his first. For some time afterwards he lived with a relative in Benthuizen, then, in 1648, moved to Amsterdam, where he was apprenticed to a cloth merchant. His unique observations on microorganisms probably began in 1674, when he examined water from a lake near Delft. In 1671 Leeuwenhoek made his first simple microscope. After his appointment to the Society, he wrote approximately 560 letters to the Society and other scientific institutions over a period of 50 years. Anton van Leeuwenhoek was a very prolific scientist and had a very long life, dying at the age of 91.

What were the contributions of Anton van Leeuwenhoek made to science

His lack of formal scientific training led Leeuwenhoek to concentrate on making observations rather than offering theories. Nevertheless, Leeuwenhoek did not fully understand the function of the blood. Originally, he believed that sperm were parasites found in the male genitals. Beyond the initial discovery of the method for making small spherical lenses, van Leeuwenhoek built hundreds of microscopes and experimented with their design. The ovists thought that the follicle discovered by de Graaf and named after him was, in fact, the egg, while Leeuwenhoek pointed out that it was impossible for the entire follicle to pass through the narrow to the uterus. The capability of one of his single-lens instruments, far exceeded that of Hook's compound system. In a series of investigations Leeuwenhoek demonstrated the complex structure of mites, lice, and fleas, and described their copulation and life cycles.

Anton Van Leeuwenhoek

anton van leeuwenhoek contribution

He was a contemporary of Robert Hook and the two men share some credit for establishing that living things were made of cells. Anton van Leeuwenhoek is often credited as being the inventor of the microscope, but that is not actually the case. Leeuwenhoek was born on October 24, 1632, in Delft, Holland. He was 14 years old when he soon acquired one for his own use. Leeuwenhoek's microscopic research on the life histories of various low forms of animal life was in opposition to the doctrine that they could be produced by spontaneous generation. All his observations were described in letters at least 200 , either to the Royal Society or to his friends, that were written in his own language, Nether-Dutch.
