Of Mice and Men . This statement was made in SchwannsMikroskopische Untersuchungen ber die bereinstimmung in der Struktur und dem Wachstume der Tiere und Pflanzen(1839;Microscopical Researches into the Accordance in the Structure and Growth of Animals and Plants). 4.3: Studying Cells - Cell Theory - Biology LibreTexts Hooke made this contribution to the cell theory in 1665. The microscopes of his day were not very strong, but Hooke was still able to make an important discovery. In fact, Leeuwenhoeks microscope was almost as strong as modern light microscopes. However, that such a brilliant thinker such as Virchow was stating this was enough for many in the field to accept it as true.

The Evolution Of The Cell Theory Timeline | Preceden The scientists Matthias Schleiden and Theodor Schwann are credited with establishing the cell theory in 1839. A cell consists of a nucleus and cytoplasm and is contained within the cell membrane, which regulates what passes in and out. Schleiden was talking about his work in finding out what the nucleus of a cell did, and the more that Schleiden talked about his discoveries, the more that Schwann realized that he had seen the same thing in his own lab.
