Walther Flemming introduced the concept of “mitosis”, which he studied on stained microscopic preparations, using salamander epithelial cells as a source of biological material and contributed to the development of cell biology and its branches.
Flemming, Walther (1843-1905) German anatomist who used dyes to study the structure of cells. He found a structure which strongly absorbed dye, and named it chromatin. He observed that, during cell division, the chromatin separated into stringy objects, which became known as chromosomes.
Walter Fleming - 1879. He found that a certain class of dyes revealed threadlike material in the nucleus. He was also the first to observe and describe systematically the behavior of chromosomes in thee cell"s nucleus during normal mitosis.
In 1880 he traveled to the zoological station at Naples to study cell division in the formation of the echinoderm egg and established there also indirect division as the mechanism of cell division. Flemming’s great merit as a theoretician lay in his attempt to find a single process to fit all forms of cell division.
