Wilhelm Roux Suggests that the Nucleus Contains the Material Basis of Heredity

In Über die Bedeutung der Kerntheilungsfiguren (Leipzig, 1883) German zoologist and embryologist Wilhelm Roux presented the report of his investigation why the nucleus undergoes the precise division of mitosis while the rest of the cell undergoes a rather crude division when one cell splits into two. He argued that mitosis ensures a precise halving of the nucleus, suggesting that the nucleus contains the material basis of heredity.
