who invented the microscope?

Answer 1

References have said Gallileo invented it shortly after inventing the telescope. This is not so, as Gallileo didn't purchase his first telescope until around 1607. Many people think that Leeuwenhoek invented the microscope. This is also very untrue, as while his microscopes were very simple and crude, he started making them long after very elaborate models were available and many important discoveries had been made by them.

Answer 2

1st True MicroScope....
Sometime about the year 1590, two Dutch spectacle makers, Zaccharias Janssen and his father Hans started experimenting with these lenses. They put several lenses in a tube and made a very important discovery. The object near the end of the tube appeared to be greatly enlarged, much larger than any simple magnifying glass could achieve by itself! They had just invented the compound microscope (which is a microscope that uses two or more lenses).

Galileo heard of their experiments and started experimenting on his own. He described the principles of lenses and light rays and improved both the microscope and telescope. He added a focusing device to his microscope and of course went on to explore the heavens with his telescopes.

During the 1st century AD (year 100), glass had been invented and the Romans were looking through the glass and testing it. They experimented with different shapes of clear glass and one of their samples was thick in the middle and thin on the edges. They discovered that if you held one of these “lenses” over an object, the object would look larger. BUT these would be called Magnifying glasses
