Jul 27, 2026 · 12m
Summary
Dr. Sarah Valentine discusses her book "Decoding the Devil," revealing the overlooked history of Black women codebreakers who deciphered Soviet nuclear intelligence during the Cold War. These women performed manual data analysis, acting as early "human computers" before training the first language-processing machines. Despite their critical contributions, they faced segregation and were largely excluded from subsequent opportunities in the emerging field of computing.
