Walther Flemming (21 April 1843 – 4 August 1905) biologist and a founder of cytogenetics. He was born in Sachsenberg (now part of Schwerin ) as the fifth child and only son of the psychiatrist Carl Friedrich Flemming (1799–1880) and his second wife, Auguste Winter.

Their behavior in animal cells was described by Walther Flemming, the discoverer of mitosis, in 1882. The name was coined by another German anatomist, von Waldeyer in 1888. The next stage took place after the development of genetics in the early 20th century, when it was appreciated that the set of chromosomes (the karyotype ) was the carrier ...
The term "mitosis", coined by Walther Flemming in 1882, [23] is derived from the Greek word μίτος (mitos, "warp thread"). [24] [25] There are some alternative names for the process, [26] e.g., "karyokinesis" (nuclear division), a term introduced by Schleicher in 1878, [27] [28] or "equational division", proposed by August Weismann in 1887 ...
Mitosis was discovered several years later in 1882 by Walther Flemming. Hertwig studied sea urchins, and noticed that each egg contained one nucleus prior to fertilization and two nuclei after. This discovery proved that one spermatozoon could fertilize an egg, and therefore proved the process of meiosis.
In the mid 19th century, anatomist Walther Flemming, discovered what we now know as chromosomes and the separation process they undergo through mitosis. His work along with Theodor Boveri first came up with the Chromosomal Theory of Inheritance, which helped explain some of the patterns Mendel had observed much earlier. [7]
Van Beneden elucidated, together with Walther Flemming and Eduard Strasburger, the essential facts of mitosis, where, in contrast to meiosis, there is a qualitative and quantitative equality of chromosome distribution to daughter cells.
Although its significance for genetics and for cell biology was still to be discovered, these filaments were known to be involved in the phenomenon of cell division discovered by Flemming, named mitosis, as well as in meiosis. He coined in 1888 the term "chromosome" to describe them. [1] [2]
