He was using a microscope to observe plant cells when he noticed a small, dark object in the center of each cell. He called this object the nucleus, and he hypothesized that it was the control center of the cell.<\/p>\n<p>Robert Hooke was an English scientist who is considered to be the father of microscopy. He was the first person to observe cells, in 1665. However, he did not observe the nucleus.<\/p>\n<p>Rudolf Virchow was a German physician who is considered to be the father of cell theory.
