Known For
  • first microbiologist
  • studied the first protozoa
  • described the blood cells of the human body first correctly
  • magnified lenses to have it more than 50 times more than the human eye
Science explained
Microbiology is the science of living microorganisms such as bacteria. It is the science of the smallest living creatures on earth. It is like biology but studying smaller living creatures. Microbiology is very hard to study because the organisms scientists have to study are so small. Only a person that has such a curious mind and has a lot of skill in lenses carving, like Antonie, would be able to study microorganisms at his time (1600’s). He said that you must have a mind that is curious and wants to know more. There weren’t many microbiologists after him because it was so hard to make lenses like him and many men thought it was unimportant to know microbiology. The lenses he made magnified more than 50 times. It was also hard to have the right angle of light to magnify it completely. Studying microbiology is very interesting though because you are looking at things that the naked human eye cannot see at all and so you are looking at things so small but there are usually simple organisms, one celled organisms.
  • He was a microbiologist. He mostly worked at Delft, Netherlands but sent many letters to colleges and places like that.
Did you know?
Anton Van Leeuwenhoek was very unlikely to become a scientist and curiosity, not knowledge, led him to becoming a scientist. He was very interested in lenses making when he made his drapers business and curious on how to make the lenses better. He made the best microscope of his time. Anton was the first person to see bacteria and all sorts of microscopic organisms. He wrote letters but not papers to the world about his discoveries and monarchs came to him to see "animalcules" (animalcules were what he called the microorganisms). He ended up being the first microscopist. He first saw the many "animalcules" in a drop of water. He saw red blood cells and described it correctly first, he said it was about 25000 times smaller than a fine sand grain. He was the first to microdissected something. He had microdissected many small bugs like, aphids. When he died, he left 247microscopes and 172 mounted lenses that were auctioned by his family
