Who Are Scientists Who Invented Microscopes?


Answer:
While single lenses had been used for some considerable time to examine small items, Zaccharias Janssen and his son Hans, while experimenting with multiple lenses surrounded by a tube around 1590 in Holland, discovered that nearby objects could be greatly magnified. That was the place of birth of the modern compound microscope. In 1609, Galileo Galilei made a better version which included a focusing mechanism. Thirty years or so later, another Dutchman, Anton van Leeuwenhoek, developed this deep principle into instruments of great power which he used to make numerous scientific discoveries, and he is generally prearranged as the father of microscopy.
