This document is page 198 from the book 'How America Lost Its Secrets' (ISBN 9780451494566). It details the history of U.S. cryptology and espionage, specifically focusing on the 'Black Chamber' led by Herbert O. Yardley after WWI and its eventual closure by Secretary of State Henry Stimson in 1929. While the content is historical, the document bears a 'HOUSE_OVERSIGHT' Bates stamp, indicating it was included as part of a document production to Congress, likely related to the Epstein investigation given the file context.
