Emmy Stone

from Wikipedia, the free encyclopedia

Emmy Stein (born June 21, 1879 in Düsseldorf , † September 21, 1954 in Tübingen ) was a German botanist and geneticist.

Live and act

After training at the horticultural school in Berlin-Marienfelde, she studied at the University of Jena and received her doctorate in 1913 under Ernst Stahl . Already during the First World War she came to Erwin Baur , who held the first chair for genetics in Germany. Together with Elisabeth Schiemann and Luise von Graevenitz (1877–1921) she was his assistant. From 1923 to 1939, Emmy Stein worked for Baur at the Kaiser Wilhelm Institute for Biology in Berlin. With her work " Radium Rays on Antirrhinum " she reported for the first time at a conference in 1921 that ionizing radiation has a mutagenic effect on organisms . Six years later, Hermann Joseph Muller discovered the same effect on Drosophila - he received the Nobel Prize in Physiology or Medicine for his work.

From 1940 Emmy Stein worked with Fritz von Wettstein on the hormonal influence between the graft and the base with radium mutants and in 1948 moved with the institute, which was first moved to Hechingen and later to Tübingen , where she worked until her death. Emmy Stein, along with Paula Hertwig (1889–1983) and Elisabeth Schiemann (1881–1972), is one of the biologists who not only have made great contributions to genetics, they also stand out as personalities who “started out” were part of this new science of inheritance .
