Walther Flemming

Walther Flemming was a German scientist in the late 19th and early 20th centuries who pioneered the study of cell division. He used a microscope and special dyes to observe how chromosomes, the structures carrying genetic information, behave during cell reproduction. Flemming discovered how chromosomes align and split, laying the groundwork for understanding genetics and heredity. His detailed observations and descriptions of this process, which he called mitosis, advanced biology and provided crucial insights into how living organisms grow and develop.
