Why did Zacharias Janssen invent the microscope?

Answer 1

More than 400 years ago in Holland, Zacharias Jansenn was in the business of grinding lenses for eyeglasses.

Some of his lenses made things look bigger. He found that he could put two lenses together to make things look a LOTbigger.

So, in about 1595, Zacharias built the first microscope. ("Micro" means "small." "Scope" means "to see.")

The first microscopes made things look 20 or 30 times larger than they are. This is enough to see the details of some tiny plants and insects and animals that are too small to see with just our eyes.

Answer 2

The simplest answer is that they were created to see things, or details, that are too small for the human eye to see. Early tradesmen used simple lenses to see the intricate lines of engravings, or the clasps and fittings on jewelry. When eyeglass makers began combining pairs of carefully-ground lenses, they discovered the principle of optical magnification that is the basis for the microscope (and the telescope). In the case of the microscope, there were immediate practical applications in Biology, anatomy, and miniature mechanical gearing.

Answer 3

This historical controversy around the invention of the microscope involves credit to either Hans Lippershey or Zacharias Jansen.

The father Hans Jansen is usually credited with making the first microscopes with the help of his son Zacharias Jansen.

The matter is complex because Hans Lippershey and Hans and Zacharias Jansen were all in the business of making spectacles in the same city of Middelburg, Netherlands at the time the invention process was occurirng. Furthermore, both the telescope and compound microscope were claimed by both. In addition, Jacob Metius (also Dutch and a lens grinder) and Hans Lippershey both submitted patent applications for the telescope in 1608.

Answer 4

Zacharias Jansen was from Holland and he worked fixing the eyepieces of glasses. He saw that when he put one lens in front of the other he could see things so microscopic it was unreal. Thus Zacharias Jansen founded the first microscope.
