While still in Germany , Edinger began studying extant species from a paleoneurobiological perspective by making inferences about evolutionary brain development in seacows using stratigraphic and comparative anatomical evidence . Edinger continued her research in Nazi Germany until the night of November 9 , 1938 when thousands of Jews were killed or imprisoned in what became known as Kristallnacht . Although a visa was not immediately available for immigration to the United States , with the help of friends and colleagues who valued her work , Edinger was able to immigrate to London where she translated German medical texts into English . Eventually her visa quota number was called and she was able to immigrate to the United States where she took on a position as a research fellow at Harvard 's Museum of Comparative Zoology
