Madame Marie Curie is famous for having won two Nobel Prize--for Physics in 1903 and again in 1911 for Chemistry, but many other women have also been awarded the prize. Here are their stories.
Sigrid Undset
Sigrid Undset is one of the three Norwegian authors (and so far the most recent one) to have received the Nobel Prize for Literature. Undset received the Prize in 1928, for her powerful description of life during the Middle Ages in Scandinavia. In her lifetime, she wrote two huge novels with the background of Norway, 3- volume Kristin Lavransdatter , and 4-volume Olav Audunssønn.
Gerty Theresa Cori
Gerty and her husband, Carl Cori, moved to the United States in 1922, where the two medical doctors worked together (against the advice of their colleagues) at the Roswell Park Cancer Institute in New York, hoping to find the cure for diabetes(糖尿病). In 1947, Gerty and Carl were awarded the Nobel in Medicine, making Gerty Cori the first woman to hold the honor.
Maria Goeppert-Mayer
Born in 1906 in Germany, Maria Goeppert-Mayer moved to the US with her husband, chemist Joseph Edward Mayer, in 1930. While in the US, Goeppert-Mayer developed the nuclear shell model, for which she shared the 1963 Nobel Prize for Physics with J. Hans D. Jensen and Eugene Paul Wigner--the first woman to receive the award in 60 years.
Dorothy Crowfoot Hodgkin
Dorothy Hodgkin showed a love for science as a child, and at age 18, she began studying chemistry at a women- only Oxford college. She earned her PhD at the University of Cambridge, where she first took an interest in X ray crystallography and began studying the structure of proteins. In 1934, she moved back to Oxford, where she was appointed the university s first research chemistry fellow, a position she held until1977. Her work on mapping vitamin B12 earned her the Nobel Prize in Chemistry in 1964.
