Robert Hooke
Around 1665 Robert Hooke an English scientist discovered honey-like structures while observing a cork slice through a microscope. The hone-like structures were only cell walls which he saw because it was dead tissue but he created the term cell after seeing each individual cell making up the cell wall. -
Anton van Leeuwenhoek
About 1683, while looking through a microscope at water particles from a pond, Anton can Leeuwenhoek discovered from what is known as the very first bacteria and protozoa. This was determined because he published a letter to the Royal Society about his discovery. This however does not contradict with Robert Hooke's discovery. "Cell Theory Timeline."

Robert Brown
In the time around 1833 an English botanist known as Robert Brown discovered the nucleus in plant cells while viewing parts of plants under the microscope. This does not contradict with wither Leeuwenhoek or Hooke's discoveries because each of the three scientists just discovered new things but did not go up against each others discoveries.

Matthias Jakob Schleiden
In 1838 was studying plant structures under a microscope, and he made the first generalized statement about cells. He said plants were made of cells and cells are the building blocks of plants. By taking into count that plant cells do have a nucleus like Brown said he improved this statement/model by saying there is more to a plant cell than just the nucleus. -
Theodor Shwann
In 1839 Shwann was working in a lab with Schleiden observing animal and plant tissue, and discovered that both plants and animals are made up of cells. He was also the first to state that all plants and animals are made up of cells. This disproved the previous model/idea because Schleiden stated that only plants were made up of cells. Schwann also had said that cells were created in a fluid called blastema and that imbalances in the body created blastema that diseased cells came from. -
Rudolf Vinchow
In 1855 Vinchow had seen from other scientists that cells come from other cells and decided to do deep research on this probability. He soon discovered that cells develop from previous existing cells. He also stated disease doesn't stem from organs and that they stem from healthy cells. This improves from Shwann's model/idea because it states how diseases don't come from blastema fluid imbalances in the body.
