Antony hobby was grinding lenses and observing diverse materials through them. He was the first person to observe microorganisms (1673) using a simple microscope. In 1683, he made accurate descriptions of various types of bacteria and communicated them to the Royal Society of London. He recognized them as living crea tures (animalcules) and to Leeuwenhoek the world of "little animalcules" represented only a curiosity of nature. Their importance in medicine and in other areas of biology came to be recognized two centuries later.
