Grace Hopper (December 9, 1906—January 1,1992)
She was a computer scientist from the United States. She developed the first compiler for a computer programming language. She pioneered the idea of writing computer programs in a language close to English. She was instrumental in the establishment of testing standards for computer systems. She made important contributions to computer technology.
Barbara McClintock (June 16, 1902—September 2,1992)
She was an American scientist who won the Nobel Prize in Physiology or Medicine in 1983.She led the development of the maize cytogenetics(细胞遗传学). She discovered the process of transposition and used it to demonstrate how genes are associated with the presence or absence of certain physical characteristics in human beings. She is one of the mat famous cytogeneticists of the world.
Chien-Shiung Wu(May 31,1912—February 16,1997)
She was a Chinese-American scientist known for her work in radioactivity. She was a part of the Manhattan project where she helped develop the process of making uranium-235 and uranium-238. Her experiment established that weak interaction did not follow the law of conservation of parity. She was a winner of the first Wolf Prize in Physics and was often compared with Marie Curie, giving her nicknames like the Chinese Madame Curie.
Anita Roberts(April 3,1942—May 26,2006)
