Many people call Leeuwenhoek the inventor of the microscope although he just built microscopes that were better than any earlier ones, and he was the first to see many of the tiny plants and animals that are too small to be seen with our eyes alone. Leeuwenhoek was Dutch. He was a dry goods businessman in the city of Delft. He was also the janitor of the city hall there but he spent much of his spare time building microscopes. Under one of them he might have a thread of wool, under another a bee’s sting, and under a third a drop of water. He kept a careful record of all that he saw. Probably his biggest surprise came when he first looked through one of his microscopes at a drop of rainwater. He saw that it was full of tiny living things moving about. We know now that they were tiny plants we call bacteria. Leeuwenhoek was probably the first person ever to see bacteria. He can be called the first “microbe hunter”.
