Leeuwenhock Microscope

               The most remarkable of all the 17th century microscopist was Antonie Van Leeuwenhock who held the position of janitor at the Deft City Hall for all of his adult life (it was a sinecure). Building his own microscopes, he was the first to describe spermatozoa-reporting the discovery rather nervously, fearing it might be considered obscene. He was the first to describe structure that could only be bacteria. No one else was to see bacteria again for a century, that is, untill microscopes were devised that could magnify as well and as clearly as Leeuwenhock's tiny lenses.
