Cell
"The work of the Czech Jan Purkyně (1787–1869) and his student and collaborator Gabriel Valentin (1810–1883) was unjustly denigrated by the nationalistic Germans. They have a claim to some priority in the cell theory".Chapter 9 Johannes Müller (1801–1858) also made great contributions. "It was, however, his student Theodor Schwann (1810–1882) and Matthias Schleiden (1804–1881) who got the credit for the cell theory, despite the fact that some of their observations were not correct, and their credits to previous workers were "a travesty".p97
