Who invented the first microscope and what did it look like?

The first microscope was invented by Zacharias Janssen and his father Hans Janssen, Dutch spectacle-makers, around the year 1590. However, the credit for the invention is also sometimes given to Hans Lippershey, another Dutch spectacle-maker.
The first microscopes made by Zacharias and Hans Janssen were simple compound microscopes, which consisted of a tube with a lens at each end. The shorter lens (objective lens) was placed near the object being observed, while the longer lens (eyepiece) was positioned closer to the observer's eye. The lenses were held in place by a wooden tube. The Janssen microscope had a magnification power of about 3x or 9x.
Over time, the design of microscopes evolved, and various other inventors contributed to the improvements. For example, Robert Hooke made important contributions to microscopy in the 17th century, including the development of the compound microscope and his observations on biological specimens, which he published in his book "Micrographia."
