Answer:
Rudolf Virchow
Step-by-step explanation:
Robert Hooke was the first to view dead cells under a microscope, coining the term "cell." Matthias Schleiden, along with Theodor Schwann, concluded that all living organisms, such as plants and animals, are made of cells. Rudolf Virchow confirmed that all cells must come from pre-existing cells. (However, this is an idea he may have stolen from Polish scientist, Robert Remak.)
