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.
They were first described by Walther Flemming and Ruckert in 1882. [1] Lampbrush chromosomes of tailed and tailless amphibians, birds and insects are described best of all. [2] [3] [4] Chromosomes transform into the lampbrush form during the diplotene stage of meiotic prophase I due to an active transcription of many genes. They are highly ...
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.

It was long assumed that the midbody was simply a structural part of cytokinesis, and was totally degraded with the completion of mitosis. However, it is now understood that post-abscission, the midbody is converted into an endosome-like signalling molecule, and can be internalised by nearby cells.
Carl Friedrich Flemming (27 December 1799 – 27 January 1880) was a German psychiatrist born in Jüterbog. He was the father of cellular biologist Walther Flemming (1843-1905). After receiving his medical doctorate from Berlin , he worked as an assistant at the Irrenheilanstalt Sonnenschein (Sonnenschein mental asylum) near Pirna .
In 1885, researcher Walther Flemming described dying cells in degenerating mammalian ovarian follicles.The cells showed variable stages of pyknotic chromatin. These stages included chromatin condensation, which Flemming described as "half-moon" shaped and appearing as "chromatin balls," or structures resembling large, smooth, and round electron-dense chromatin masses.
Waldeyer also studied the basophilic stained filaments which had been found to be the main constituents of chromatin, the material inside the cell nucleus, by his colleague of Kiel, Walther Flemming (1843–1905).
