Biographies of Female Mathematicians
This is another nice resource provided by the School of Math and Statistics at the University of St. Andrews, Scotland: a collection of biographies of female mathematicians.
There are around 150 mathematicians profiled here. Each profile consists of a biography, a list of references, and links to other internet resources on the individual.
Among those profiled here are Maria Agnesi (of the Witch of Agnesi cubic curve), Emmy Noether (of Noetherian Ring fame), and Mary Ellen Rudin (topologist, and wife of Walter Rudin, a noted figure in Real Analysis).
