What did Zacharias Janssen discover?
compound microscope
A Dutch father-son team named Hans and Zacharias Janssen invented the first so-called compound microscope in the late 16th century when they discovered that, if they put a lens at the top and bottom of a tube and looked through it, objects on the other end became magnified.
What discoveries were made with the microscope?
Leeuwenhoek observed animal and plant tissue, human sperm and blood cells, minerals, fossils, and many other things that had never been seen before on a microscopic scale. He presented his findings to the Royal Society in London, where Robert Hooke was also making remarkable discoveries with a microscope.

What was the microscope called?
Galileo called his device an occhiolino, or “little eye.” English scientist Robert Hooke improved the microscope, too, and explored the structure of snowflakes, fleas, lice and plants.

3)Hans and Zacharias Janssen Cell Theory was first discovered after they developed the microscope. Subsequently, question is, what did Zacharias Janssen contribute to the cell theory? Zacharias Janssen contributed to cell theory with the invention of the single-lens microscope and that of multiple lenses for cell discovery. He was able to develop this invention due to his knowledge of the family lineage of lens manufacturers.
When did Zacharias Janssen discover the microscope?
Zacharias Janssen was a spectacle maker in the late 16th and early 17th century. He is credited with making the earliest compound microscope in the 1590s. While Zacharias is credited with the invention of the microscope, as well as the telescope, the invention is dated to his teenage years, so it is likely that his father played a role.
How did Zacharias Janssen contribute to the cell theory?
Zacharias Janssen was born in 1585 and died in 1638. Hans was born in 1601 and died in 1645. Hans and Zacharias Janssen are known for inventing the compound optical microscope. They made it in the 1590’s. This contributed to “The Cell Theory” by making it easier and more practical whilst observing cells.
