Who invented the microscope?
The inventor of the microscope is still disputed. During the first century AD itself, the Romans invented glass, and tried out many uses of the substance, including microscopic views.
However, the most noted microscope was developed by a Dutch duo, Hans and Zacharias Janssen. They invented the first compound microscope in the 16th century. They discovered that, if they put a lens at the top and bottom of a tube and looked through it, objects at the other end became magnified.
Later, Anton van Leeuwenhoek improved the microscope. Using handcrafted microscopes, he became the first person to observe single celled organisms. These preliminary microscopes had many drawbacks like distortion. These were sorted out over the centuries, especially with the introduction of the electron microscope.
