Antonie van Leeuwenhoek (1632 - 1723)

Antonie van Leeuwenhoek was born in Delft on October 24, 1632. In 1648, van Leeuwenhoek might have first met the magnifying glasses used in the textile industry to calculate the line density for the purpose of quality control as an apprentice of the textile trader. At the age of 20, he returned to Delft and dressed as linen. He prospered, appointed Chamberlain of Delft sheriff in 1660, became a surveyor nine years later.

In 1668, Juan Lee Wen Hook visited London for the first time, and the only time he may have watched a copy of Robert Hook's "Micrographia" (1665) containing photographs of the textile he was interested in It was. In 1673, he reported his first observation to the Royal Society - bees mouth and bite, human lice and fungus. He was elected as a member of the Association in 1680 and continued his life through a letter.

In 1676, van Leeuwenhoek carefully observed the water and was surprised to see the microorganisms - the bacteria that the human observe first. In his letter of announcing discovery, he caused extensive doubt by the Royal Society, but Robert Hook repeated experiments later and confirmed his findings.

In addition to being a father of microbiology, van Leeuwenhoek has built the foundation of plant anatomy and became an animal breeding expert. He discovered blood cells and microscopic nematodes and studied the structure of trees and crystals. He also made over 500 microscopes to observe specific objects.

He also discovered sperm that I believe is one of the most important discoveries in his career and explained sperm from molluscs, fish, amphibians, birds and mammals, and spermatozoa Conclusion When wearing Fertilization occurs when eggs pass through

Over the next few years, other scientists will be based on Hook's work, including Antony van Leeuwenhoek (1632-1723), a textile dealer located in Delft, The Netherlands. Van Leeuwenhoek is not a trained scientist, but he is a diligent and curious person and I am very happy to be able to observe the world around me (Anderson, 2009). During his work at a department store in the 1770's, van Leeuwenhoek started experimenting with glass blowing and microscope construction (Figure 2). Using Hooke's design described in Micrographia, van Leeuwenhoek handmade his own microscope.

In the 18th century, Dutch microscopist Antonie van Leeuwenhoek (1632-1723) discovered "microorganisms" in sperm of humans and other animals. Some scientists speculate that they will see "dwarfs" (cerebellum) in each sperm. These scientists formed a school called "sperm scholars". They believe that the only contribution women make to the next generation is the prenatal effect of the uterus and the uterus where the asiatic pouch grows. Opponents' schools, eggs, think that future human beings are in eggs, and sperm only stimulates the growth of eggs. Ovum believes that women have eggs including boys and girls and will decide their gender before pregnancy.
