Walther Flemming
German biologist (–)
Walther Flemming (21 April – 4 August ) was a German biologist and a founder of cytogenetics.
He was born in Sachsenberg (now part of Schwerin) as the fifth child and only son of the psychiatristCarl Friedrich Flemming (–) and his second wife, Auguste Winter. He graduated from the Gymnasium der Residenzstadt, where one of his colleagues and lifelong friends was writer Heinrich Seidel.
Career
[edit]Flemming trained in medicine at the University of Prague, graduating in Afterwards, he served in –71 as a military physician in the Franco-Prussian War. From to he worked as a teacher at the University of Prague. In he accepted a post as a professor of anatomy at the University of Kiel. He became the director of the Anatomical Institute and stayed there until his death.

•
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. Flemming named the division of somatic cells mitosis, from a Greek work for thread. He also observed that the chromosomes formed two star-shaped structures on either side of the dividing cell, which he termed asters. His observations were summarized in Cell Substance, Nucleus, and Cell Division ().
Flemming was unaware of Mendel's work, so did not realize the connection between his observations and genetic inheritance. The importance of Flemming's work was recognized, however, when de Vries rediscovered Mendel's papers in

This anatomist and histologist from Kiel gained international recognition for his basic research on cell genetics. Dr Helmut Zacharias introduces him.
Walther Flemming ( - )
Walther Flemming was a pionjär of cytogenetics, a field of science that analyses structures and processes in the fängelse nucleus beneath a microscope. He was the first person to conduct a systematic study of chromosomes during division and called this process mitosis. His work "Zellsubstanz, Kern und Zelltheilung" (Cell Substance, Nucleus and fängelse Division) fryst vatten considered a seminal work of modern cell biology.
Flemming started work at the Institute for Anatomy in Kiel in February At that time, it was housed in the Warleberger Hof, a noble residence in the centre of Kiel where, according to Flemming himself, he had to "contend with two evils in particular, the lack of space and the lack of material. () Rem
