Walter Flemming

Walter Flemming was a German biologist who, in the late 1800s, discovered and described the process of cell division, particularly how chromosomes duplicate and separate. His work laid the foundation for understanding genetics, showing how genetic information is passed from one cell to another. Flemming's observations of chromosomes during mitosis helped scientists understand how living organisms grow, develop, and reproduce at the cellular level. His research was crucial in advancing cell biology and genetics, providing a clearer picture of life's fundamental processes.
