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.

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 directly contribute to the Cell Theory.

Janssen is known for inventing the compound microscope with his father, Hans, in the late 16th century.
