Robert Hooke's Discovery of Cells in 1665

Robert Hooke, an English natural Philosopher , was the first person to discover cells using the microscope. As he was observing a tiny piece of cork tissues during 1665, he discovered the cells and the cell walls within it. He then, applied the term "cells" for them in his book. The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells.
Even though Robert Hooke had great contributions to the establishment of the cell theory, he did not know much about them, such as their structure and function.
The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria.

Advances in Microscopy - Anton Leeuwenhoek

Antonie Philips van Leeuwenhoek , a dutch scientist, is best known for his contributions to the improvement of the microscope's design and use. He made over 500 microscopes.
With his handcrafted microscope, he was the first man to witness live single celled organisms and referred them as microorganisms. Some of these organisms came out to be bacteria and thus, Leeuwenhoek also was the first person to discover bacteria. He is known as the father of microscopy due to his incredible contributions and it can also be said that he had the most contributions to the establishment of the cell theory.
