Many women who did physics research in the first half of the 20th century worked in the field of nuclear physics. Therefore we have a section on early nuclear physics which provides a historical context for the role of some women in the CWP archive. 

Also we present a section on missing elements in the periodic table. In 1920 there were still six elements missing from the periodic table, which, at the time ended with atomic number 92 (Uranium). All these elements were discovered during the next 25 years. Three of the elements were discovered by women physicists, and this section briefly outlines their role.

Finally, we include a section on nuclear fission which was discovered by Lise Meitner, Otto Hahn and Arnold Strassmann. This section describes the history leading up to this discovery and includes the important work of other women who were working in the field at that time.
