Only by making homemade utensils from a magnifying glass, Anton van Leeuwenhoek discovered bacteria and became the first person to observe the nucleus that helps maintain the human race.
Bacteria are a special living organism and are present in most surfaces and environments. The attraction of the living world of viruses hidden deep in layers of cloth, water droplets, ponds, and lakes is the basis for microbiologist Anton van Leeuwenhoek to discover sperm.
Bacteria (sometimes called bacteria) have been around for a long time on Earth. According to Britanica, there is a strong view that bacteria originated about 3.5 billion years ago, in the Precambrian Era. In 2017, Livescience published information about a collection of fibrous fossils in Australia. The team thinks these are the remains of a microbial carpet that can absorb the sun's energy, dating back about 3.5 billion years.
The evidence for the world's oldest life is that the rocks in Greenland - the complex is thought to contain fossils of bacteria 3.7 billion years old, forming a multi-layered structure, also known as stromatolite. .
The size of most bacteria is very small, only about 0.5-5.0 μm. Bacterial ancestors are unicellular organisms and quickly exist on nearly all surfaces. This is the largest group present in the world. Their habitat can be soil, water, radioactive waste, hot springs or even in human parts.

The first scientist to study and describe the bacterium was A nton van Leeuwenhoek (1632-1723). Thanks to that, he became the first person in the world to observe sperm.
When young, Anton van Leeuwenhoek soon lost his father. Later, his mother married painter Jacob Jansz Molijn. When his stepfather died in 1648, Anton was sent to Amsterdam (England) to help work as a cloth seller.

At the age of 20, he returned to his hometown in Deft City and opened his own tailor shop. By 1660, when the job was stable and had a foothold in the textile industry, Anton began to spend time observing the smallest details of the fabrics to assess the quality.
Thanks to this, Anton van Leeuwenhoek discovered the most special living thing on Earth. In his studies, he described bacteria as strange round creatures.
In 1668, on a business trip to England, he bought magnifying glass and created his first crude microscope. The curiosity of the vivid world hidden inside material surfaces led Anton to stumble upon the bacteria.
Leeuwenhoek built a microscope that consisted of only one lens with a short focal length. This type of structure was the most preferred type of compound microscope at the time. Leeuwenhoek's studies did not follow any formal scientific process, but his careful, meticulous observation abilities led the father of microbiology to find interesting things.
In 1674, he first observed the protozoa, a few years later it was a bacteria. Anton took observation samples from everything possible in the surrounding life such as rain water, well water, drool in human mouth. In each environment, Anton calculated the size of each microorganism he observed.
The world lived behind a simple microscope that had a strong attraction for a man from the Netherlands. In 1677, he described sperm for the first time from observation samples of insects, dogs and a man.

Gizmodo describes the circumstances when Anton discovered that the nucleus helps to maintain the human race. It was one morning after having sex with his wife, the man immediately looked for the familiar microscope and searched for life in semen drops.
In his letter to the Royal Institution, Anton described the sperm as 'tiny animals'. 'They have a flat head and an almost transparent long tail. They move like a snake, eel swimming in the water '. For Dutch merchants, the discovery of sperm is the most important achievement in his career exploring the microscopic world.
Thanks to a homemade microscope, Anton van Leeuwenhoek was also the first to observe the breeding process of ants, the period when the larvae split the cocoon membrane and grow into ants. Therefore, Anton van Leeuwenhoek is considered to be the foundation of plant anatomy, an expert in animal reproduction. He also discovered blood cells and microscopic nematodes, and studied the structure of wood and crystals.
However, Anton van Leeuwenhoek's method of making a microscope was a mystery he never revealed to anyone. During his life, he created more than 500 lenses, most of them very small.
