NSA/CSS Inducts Four Pioneers into the National Cryptologic Museum's Hall of Honor

FORT MEADE, Md.  –  

Four pioneers of American cryptology were inducted into the NSA/CSS Hall of Honor today at the National Cryptologic Museum. In his keynote remarks during the induction ceremony, John C. Inglis, Deputy Director, National Security Agency, highlighted the distinguished achievements of each of the inductees:

  • Mr. Joseph Amato was an innovative manager whose knowledge, management expertise, and vision enhanced crucial collection resources and analytic efforts concerning a major threat to U.S. security during the Cold War.
  • Mr. David Boak was a communications security professional who developed new schemes for determining the strength of cryptographic equipment and was particularly known for his series of lectures known as the "Boak Papers," a collected work often compared in scope and influence with William Friedman's famous lectures on communications intelligence.
  • Ms. Genevieve Grotjan Feinstein was a brilliant cryptanalyst whose findings led to breaking the Japanese code, PURPLE, in time for World War II and later decrypting the Russian KGB messages during the Cold War while working on the VENONA project.
  • Mr. Leo Rosen was a pioneer in machine processing systems whose work was exemplified by his creation of a device that duplicated the function of the Japanese machine cipher system known as "Purple" and laid the foundation for much of the future U.S. excellence in cryptologic technology.

The Hall of Honor, created in 1999, pays tribute to the pioneers and heroes who have made significant and enduring contributions to American cryptology. For more information on the NSA/CSS Hall of Honor or the National Cryptologic Museum, visit the NCM homepage at
