he experimented with multiple lens placed in a tube. the object in front of the tube appeared greatly enlarged
1590
He made his first simple lens microscope in 1595.
Theodor Schwann did not invent the microscope. He was a German physiologist who made significant contributions to the cell theory in the 19th century, but the invention of the microscope is credited to Zacharias Janssen and Hans Lippershey in the late 16th century.
question for you what did the jansen brothers discover?
He made his first simple lens microscope in 1595.
He is the first inventor to invent the compound microscope
FYI he did not invent the microscope the Romans did search it on the web
Zacharias Janssen (Netherlands) invented the telescope and perhaps the compound micoscope in 1590.
Zacharias Janssen was the first person to invent the microscope and the kind of microscope he made was a compound microscope--a microscope that uses two or more sets of lenses. Plus, the first compound microscope (by Zacharias) was made around 1595 in Middleburg, Holland.
No, Thomas Edison did not invent the microscope. The microscope was actually invented by Dutch spectacle maker Zacharias Janssen and his father Hans in the late 16th century. Edison is best known for his inventions in the field of electricity and communication, such as the phonograph and the incandescent light bulb.
Zacharias Janssen was the first person to invent the optical telescope. He is also known as the inventor of the compound microscope.
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.
