This is actually a collection of links to biographies, so the amount of information varies. This encyclopedia began as a classroom assignment for third and fourth grade students. They were told to write research papers on figures in Women's History. They could not find a Web site on Women's History, so they put the papers on the World Wide Web. Some women have more than one entry.
Some entries are better than others.
The introduction and instructions have more information. This site has biographies of African Americans in the Sciences, arranged alphabetically. There are also links to a list of the women featured, and a list of the first African Americans to get a degree in the subjects covered. Each biography has a picture of the person, birth and death dates, field of study, a biography, and a bibliography telling where you can find more information on the person. Some biographies are long, others are much shorter.
