ANTON VAN LEEUWENHOEK BIOGRAPHY PDF

Leeuwenhoek was born in Delft, Holland on October 24, His father was a basket-maker, and although Leeuwenhoek did not receive a university education and was not considered a scholar, his curiosity and skill allowed him to make some of the most important discoveries in the history of Biology. He was educated as a child in the town of Warmond, lived with his uncle in Benthuizen, and apprenticed in as a fabric merchant. He returned to Delft, and established his own business as a fabric merchant, but also worked as a surveyor, a wine assayer and as a city official. At some time before , Antonie van Leeuwenhoek learned to grind lenses, and used these to make very simple hand-held microscopes.

Anton van Leeuwenhoek October 24, —August 30, invented the first practical microscopes and used them to become the first person to see and describe bacteria, among other microscopic discoveries.

Indeed, van Leeuwenhoek's work effectively refuted the doctrine of spontaneous generation , the theory that living organisms could spontaneously emerge from nonliving matter. His studies also led to the development of the sciences of bacteriology and protozoology.

Leeuwenhoek was born in Holland on October 24, , and as a teenager he became an apprentice at a linen draper's shop. Although it doesn't seem a likely start to a life of science, from here Leeuwenhoek was set on a path to inventing his microscope. He was inspired and taught himself new methods for grinding and polishing tiny lenses of great curvature, which gave magnifications up to x times the subject's original size , the finest known at that time.

People had been using magnifying lenses since the 12th century and convex and concave lenses for vision correction since the s and s. In , Dutch lens grinders Hans and Zacharias Janssen constructed a microscope with two lenses in a tube; though it may not have been the first microscope, it was a very early model. Also credited with the invention of the microscope about the same time was Hans Lippershey, the inventor of the telescope.

Their work led to others' research and development on telescopes and the modern compound microscope, such as Galileo Galilei, Italian astronomer, physicist, and engineer whose invention was the first given the name "microscope. The compound microscopes of Leeuwenhoek's time had issues with blurry figures and distortions and could magnify only up to 30 or 40 times.

Leeuwenhoek's work on his tiny lenses led to the building of his microscopes, considered the first practical ones. They bore little resemblance to today's microscopes, however; they were more like very high-powered magnifying glasses and used only one lens instead of two. Other scientists didn't adopt Leeuwenhoek's versions of microscopes because of the difficulty in learning to use them.

They were small about 2 inches long and were used by holding one's eye close to the tiny lens and looking at a sample suspended on a pin. With these microscopes, though, he made the microbiological discoveries for which he is famous. Leeuwenhoek was the first to see and describe bacteria , yeast plants, the teeming life in a drop of water such as algae , and the circulation of blood corpuscles in capillaries. 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.

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.

Antonie van Leeuwenhoek (1632 - 1723)

Antonie van Leeuwenhoek , born October 24, , Delft , Netherlands—died August 26, , Delft , Dutch microscopist who was the first to observe bacteria and protozoa. His researches on lower animals refuted the doctrine of spontaneous generation , and his observations helped lay the foundations for the sciences of bacteriology and protozoology. Antonie van Leeuwenhoek used single-lens microscopes , which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas , mussels , and eels helped disprove the theory of spontaneous generation of life. Through his microscopic observations of organisms such as bacteria and protozoa , Antonie van Leeuwenhoek effectively began the discipline of microbiology.

Biography of Antonie van Leeuwenhoek, Father of Microbiology

British Broadcasting Corporation Home. Antony Van Leeuwenhoek, c. Antonie van Leeuwenhoek was born in Delft on 24 October In , van Leeuwenhoek was apprenticed to a textile merchant, which is where he probably first encountered magnifying glasses, which were used in the textile trade to count thread densities for quality control purposes. Aged 20, he returned to Delft and set himself up as a linen-draper. He prospered and was appointed chamberlain to the sheriffs of Delft in , and becoming a surveyor nine years later.

Antony van Leeuwenhoek (1632-1723)

A largely self-taught man in science, he is commonly known as " the Father of Microbiology ", and one of the first microscopists and microbiologists. Raised in Delft , Dutch Republic , van Leeuwenhoek worked as a draper in his youth and founded his own shop in He became well recognized in municipal politics and developed an interest in lensmaking. In the s, he started to explore microbial life with his microscope. Most of the "animalcules" are now referred to as unicellular organisms , although he observed multicellular organisms in pond water. He was also the first to document microscopic observations of muscle fibers, bacteria , spermatozoa , red blood cells , crystals in gouty tophi , and blood flow in capillaries. Although van Leeuwenhoek did not write any books, his discoveries came to light through correspondence with the Royal Society , which published his letters.
