During World War 11, a unit of African American women secretly worked as code breakers in Arlington as part of America’s massive intelligence operation, which employed roughly 10,000 women code breakers. Their command center was Arlington Hall Station, a former women’s junior college that became a key wartime cryptography center. Much more is known about the white women who broke military codes. But African-American code breakers were hidden until historians at the National Security Agency uncovered the details in secret files.  They worked on commercial codes and identified companies making deals with our wartime enemies.  Help celebrate Black history month by learning about the accomplishments of these men and women.

Dr. David A. Hatch is the NSA Historian and Technical Director of the Center for Cryptologic History at the National Security Agency. Dr. Hatch came to NSA in 1973 after military service. After several decades of a distinguished career, Dr. Hatch joined the Center for Cryptologic History in 1990, and became its Director three years later. In 2002, he became its Technical Director. He holds an M.A. in East Asian Studies from Indiana University and a Ph.D. in International Relations from American University.  Dr. Hatch is author of several classified monographs and numerous unclassified articles on NSA history. He is also an adjunct history professor at the Johns Hopkins University adult education program and at Catonsville Community College.
