The Father of Microbiology and the Microscope

For a long time the circulatory system presented an intemperate puzzle. People could observe arteries and veins, and see that these blood vessels branched by into smaller and thinner vessels. Some observers speculated that blood from the arteries returned to the heart by dint of veins. However, they had had no means to investigate this. They had reached the limits of human sight. The invention of the esthesis lens microscope by Leeuwenhoek, who was the first to observe unicellular organisms, furious 1668 allowed scientists for the first time to view the most basic dowery of life, the cell. Antony van Leeuwenhoek was an unlikely scientist, born in 1632 into a family of tradesmen in Delft, Holland. He had no fortune, no university education, and knew barely his native language, Dutch. His bilk of any formal qualifications or wealth would seem to clear great odds against him for success in the scientific appoint of his time. However Leeuwenhoeks determination and cur iosity allowed him to succeed in excogitate important discoveries in the field of biology. Leeuwenhoek is best known for his cabbage of the microscope. As a hobby Leeuwenhoek ground lenses and used them to acquire tiny objects. Using these lenses, he observed protozoa in pond water and bacteria in the human brink and intestine. He gave the first full descriptions of bacteria, protozoan, and spermatozoa.

The lenses allowed him to discover blood corpuscles and capillaries, and to a fault to describe the structure of muscles and nerves. His observations laid the foundations for bacteriology and protozoology. In 1595, nearly 40 geezerhood prior to Le! euwenhoeks birth, compound microscopes had been invented in England by Robert Hooke and in the Netherlands by Jan Swammerdam. These compound microscopes were similar to the ones in use right away tho only increased the magn/;ification power by only 20x. Leeuwenhoeks delight in...
