Vera Danchakoff

Vera Mikhaĭlovna Danchakoff (née Grigorevskaya, March 21, 1879 – September 22, 1950) was an anatomist, cell biologist and embryologist from the Russian Empire. In 1908 she was the first woman in the Russian Empire to be appointed as a professor and she became a pioneer in stem cell research. She emigrated to the United States in 1915 where she was a leading exponent of the idea that all types of blood cell develop from a single type of cell. She has sometimes been called "the mother of stem cells". She later returned to Europe to continue with her research. Provided by Wikipedia
