The Dutch people who have a history and tradition in inventing and discovery gave a great contribution to science. They were the pioneers of microscopy. Their phenomenal contribution was producing the small but powerful lenses with which they probe at the frontier of the micro world. The first compound microscope was invented in 1590 by the father and son Dutchmen Hans and Zacharias Janssen. Their invention would have a single glass lens for the objective and another single glass lens for the eyepiece as seen in their own microscope diagram.
