Notable Twentieth-Century Scientists

The Supplement provides an additional 225 profiles on internationally renowned scientists, with special attention to women and minorities.

In addition to 230 new entries, the Supplement also updates approximately 70 scientists (those who have died since 1994) from the original set. Each 400- to 1,750-word essay provides personal and career information mad includes a list of major writings, resources for further information and, when available, a personal statement from the scientist. Approximately 300 photos are included, as well as a general bibliography and a timeline of scientific achievements. Additional access to entries is available through four indexes that cover both the supplement and the original 4-vol. set.
