Hans and Zacharias Janssen invented the first compound microscope.They did not discover it.
they did something about cells......I think -1950. Dutch eyeglass makers, such as Zacharias Janssen ( exact dates unknown ), invent the first compound microscopes, by lining up two lenses to produce extra-large images.

Hans Janssen was born on November 24, 1590, in the Netherlands. He was a skilled optician and invented the compound microscope with his son Zacharias Janssen in the late 16th century. Their invention revolutionized the field of microscopy and laid the foundation for modern optical instruments.
The compound microscope was invented by Zacharias Janssen in the late 16th century, although others like Hans and Zacharias Janssen, Hans Lippershey, and Hans Martens claim to have contributed to its development. The electron microscope was later invented in the 20th century by Ernst Ruska and Max Knoll.
