One scientist who contributed to cell theory was Rudolph Virchow. What he did that had to do with the cell theory was that he stated that all living things come from other living things.
The cell was first discovered by Robert Hooke in 1665 using a microscope. The first Cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s.https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=who%20found%20out%20about%20cells
Charles Darwin is considered to be one of the most influential scientists of all time. Louis Pasteur's portrait in his later years. Marie Curie is known for her contributions to physics and chemistry.
Janssen’s invention of the microscope , with the aid of his father Hans, allowed English scientist Robert Hooke to use a primitive microscope to view the cell walls of a piece of cork in 1663.
Robert Hooke
1663 - 1665
The cell was discovered by Robert Hooke in 1665. He examined very thin slices of cork and saw a multitude of tiny pores that he remarked looked like the walled compartments a monk would live in. Because of this association, Hooke called them cells, the name they still bear. However, Hooke did not know their real structure or function. Hooke’s description of these cells was published in Micrographia. His cell observations gave no indication of the nucleus and other organelles found in most living cells.
Anton Van Leeuwenhoek
1674 - 1683
Anton van Leeuwenhoek was inspired by the glasses used by drapers to inspect the quality of cloth. He taught himself new methods for grinding and polishing tiny lenses of great curvature which gave magnifications up to 270x diameters, the finest known at that time.
These lenses led to the building of Anton Van Leeuwenhoek’s microscopes considered the first practical microscopes, and the biological discoveries for which he is famous. Anton Van Leeuwenhoek was the first to see and describe bacteria (1674), yeast plants, the teeming life in a drop of water, and the circulation of blood corpuscles in capillaries. During a long life he used his lenses to make pioneer studies on an extraordinary variety of things, both living and non-living, and reported his findings
Theodor Schwann
1837 - 1839
Matthias Schleiden found that all plants are composed of cells, and communicated the finding to Schwann, who had found similar structures in the cells. Other researchers confirmed the similarity, as explained in his book, where he concluded, "All living things are composed of cells and cell products. This became the cell theory
Matthias Schleiden
1839
He stated that the different parts of the plant organism are composed of cells. Thus, Schleiden and Schwann became the first to formulate what was then an informal belief as a principle of biology equal in importance to the atomic theory of chemistry. He also recognized the importance of the cell nucleus, and sensed its connection with cell division..
Rudolph Virchow
1855
Rudolph Virchow suggested that all cells come from pre-existing cells. His aphorism’omnis cellula e cellula’ meaning every cell from a pre-existing cell became the foundations of division, even if the process was not fully understood then. He also stated that not all plants are made up of cells,which eventually lead to the creation of the cell theory.

The observations of Robert Hooke, Anton van Leeuwenhoek, Matthias Schleiden, Theodor Schwann, Rudolf Virchow, and others led to the development of the cell theory. The cell theory is a widely accepted explanation of the relationship between cells and living things.http://www.bing.com/
Hans and Zacharias Janssen had to first develop the microscope before cells could be discovered. Robert Hooke then discovered empty, dead cork cells in tree bark. Anton van Leeuwenhoek discovered the existence of living cells and is sometimes given credit for the microscope.
The Cell Theory was developed from three German scientist's discoveries. They are Matthias Schleiden, Theodor Schwann, and Rudolph Virchow. In 1838 the German Botanist Matthias Schleiden discovered that all plants were composed of cells.
Theodor Schwann German physiologist and histologist who in 1838 and 1839 identified the cell as the basic structure of plant and animal tissue (1810-1882
Robert Hooke 1665 -English scientist that cut a thin slice of cork and looked at it under his microscope. To him, the cork seemed to be made up of empty little boxes, which he named cells.

When Hooke viewed a thin cutting of cork he discovered empty spaces contained by walls, and termed them pores, or cells. The term cells stuck and Hooke gained credit for discovering the building blocks of all life. Hooke calculated the number of cells in a cubic inch to be 1,259,712,000, and while he couldn't grasp the full effect of his discovery, he did at least appreciate the sheer number of these cells.2

One of the scientists is Matthias Schleiden. He figured out that all plants are made of cells, before that people thought that only human and animals were made of cells.

Robert Hooke when he was eating put a piece of food underneath a microscope and found that they a mini shell type organisms so he named them cells.
When Hooke viewed a thin cutting of cork he discovered empty spaces contained by walls, and termed them pores, or cells. The term cells stuck and Hooke gained credit for discovering the building blocks of all life. Hooke calculated the number of cells in a cubic inch to be 1,259,712,000, and while he couldn't grasp the full effect of his discovery, he did at least appreciate the sheer number of these cells.2
