Zacharias Jansen (c. 1580 - c. 1638) was a Dutch spectacle-maker credited with inventing the first microscope. By the end of the seventeenth century, further developments by Anton van Leeuwenhoek and Robert Hooke allowed Jansenâ??s microscope to be expanded on and this led to the observation of cells under a microscope.
Zacharias Janssen did not directly contribute to the Cell Theory. The Cell Theory was primarily developed by scientists such as Matthias Schleiden, Theodor Schwann, and Rudolf Virchow in the 19th century. Janssen is known for inventing the compound microscope with his father, Hans, in the late 16th century.
Based on the timeline of the cell theory, father and son, Hans and Zacharias Janssen started produced the first compound microscope. They combined two convex lenses within a tube. This was in the year 1595.
Hans and Zacharias Janssen are credited with inventing the first compound microscope in the late 16th century. Their work contributed to the development of the cell theory, which states that all living organisms are composed of cells.

Their microscope allowed scientists to observe and study cells for the first time, ultimately leading to the discovery of the cell as the basic unit of life.
Hans and Zacharias Janssen are famous for making the first "simple" microscope which helped to discover cells and that everything is made up of living cells etc. They help us understand the cell structures of a living thing.

Because it helped with the cell theory.
