He was one of the first biologists to discover the living cell in organisms
Leeuwenhoek was the first person to see bacteria. He also observed organisms in water and was the first to see them. He used his own microscope that he made himself.
Antonie Philips van Leeuwenhoek (in Dutch also Anthonie, Antoni, or Theunis, in English, Antony or Anton) [1] (born on October 24, 1632 - baptized on November 4, and buried on August 30, 1723) was a Dutch tradesman and scientist from Delft, the Netherlands. He is commonly known as "the Father of Microbiology", and considered to be the first microbiologist. He is best known for his work on the improvement of the microscope and for his contributions towards the establishment of microbiology. Using his handcrafted microscopes he was the first to observe and describe single celled organisms, which he originally referred to as animalcules, and which we now refer to as microorganisms. He was also the first to record microscopic observations of muscle fibers, bacteria, spermatozoa and blood flow in capillaries (small blood vessels). Van Leeuwenhoek never wrote a book, just letters.From Wikipedia; see http://en.wikipedia.org/wiki/Anton_van_Leeuwenhoek
one of the most famous things he saw were "little animals". no one knows how he did it because he always kept it a secret.
He wasn't looking for anything specific, and certainly was not trying to discover micro-organisms; he just thought that with enough magnfication it might be possible to see something that has not previously been seen, as indeed proved to be the case.
he created the simple modern microscope so that people in the world today or during that time could see things that the naked eye itself couldn't see. Also he found bacteria and other germs that could harm people therefore saving us from germs

Anton van Leeuwenhoek is the Dutch scientist who first observed sing celled organisms under a microscope. Leeuwenhoek is considered the first microbiologist.
Anton Van Leeuwenhoek discovered plaque on peoples teeth
Anton Van Leeuwenhoek's was a Dutch cloth merchant built the first microscope. Through this apparatus he observed 'animalcules', which were actually bacteria.
Anton Van Leeuwenhoek did not see organ system, but he did look at living organisms such as paramecium and others.
I don't exactly know but I think Leeuwenhoek invented the microscope.
For constructing microscopes so well that many small organisms were seen for the first time ever. The Royal Society sent an observer to see the work of Leeuwenhoek, but Leeuwenhoek died with the drop glass method for making microscopes as well as he did and the method was not rediscovered for many years.
One of the inventions of Anton Van Leeuwenhoek is the Microscope
He had improved the microscopes that can see things we could of never saw.
