Hugo von Mohl

The Mitosis Master

On April 8, 1805, Hugo von Mohl was born.

The most significant "botanist of his day," it said in one newspaper.

A German botanist, he was the first to propose that new cells are formed by cell division. Hugo von Mohl discovered mitosis. He discovered chloroplasts - describing them as discrete bodies within the green plant cell in 1837. In 1846, he called the sap in plant cells "the living substance of the cell" and created the word "protoplasm."
