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 and Zacharias Janssen invented the first compound microscope.They did not discover it.
Combined too convex lenses within a tube, thus constructing the forerunner of the compound microscope
him and his son helped invent the compound microscope by putting two lenses together warning they did not invent the microscope but did invent the compound microscope

Hans and Zacharias Janssen invented the first compound microscope.They did not discover it.
Hans and Zacharias Janssen invented the compound microscope in 1595.
Hans and Zacharias Janssen are credited with inventing the first compound microscope in the late 16th century. Their creation revolutionized the field of optics and laid the foundation for modern microscopy.
Zacharias Janssen did not contribute to the cell theory. He is credited with inventing the first compound microscope in the late 16th century with his father, Hans Janssen. This invention was crucial for the development of cell theory by later scientists.
Zacharias Janssen was born In 1580.

Hans Janssen was the supposed creator of the microscope, along with his son, Zacharias Janssen. Actually, Hans Janssen was the son of Zacharias Janssen, not the other way around. And yes they did invent the first Compound Microscope in the year 1590.
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.
