Matthias Schleiden
He became professor of botany at the University of Dorpat in 1863. He concluded that all plant parts are made of cells and that an embryonic plant organism arises from the one cell.

Theodor Schwann

Theodor Schwann
Theodor Schwann (German pronunciation: [ˈteːodoːɐ̯ ˈʃvan] 7 December 1810 – 11 January 1882) was a German physician and physiologist. His most significant contribution to biology is considered to be the extension of cell theory to animals.

and Rudolf Virchow

Rudolf Virchow
Virchow is credited with several key discoveries. His most widely known scientific contribution is his cell theory which built on the work of Theodor Schwann. He was one of the first to accept the work of Robert Remak who showed that the origin of cells was the division of pre-existing cells.
