2nd Edition PHOENIX Memorial CDROM
A member reported that the links on the index page of the 2nd Edition PHOENIX Memorial CDROM did not work with Acrobat Reader v9. It turned out to be caused by the default value of a preference option. Here is how it was corrected:
Documents->View Documents in PDF/A mode: NEVER
From the Edit menu, select "Preferences", then choose to look under Category "Documents".
The option "View Documents in PDF/A mode" should be changed to "Never".

The Center for Cryptologic History is pleased to announce the upcoming 2013 Henry F. Schorreck Memorial Lecture. The Schorreck Lecture is a series of historical lectures named in honor of the former NSA Historian. It is presented annually by preeminent scholars who address cryptologic issues with an historical perspective. Previous talks have been delivered by scholars in the field such as David Kahn, Christopher Andrew, John Ferris, and Stephen Budiansky.
The speaker this year will be Dr. Peter W. Donovan of the Department of Mathematics, University of New South Wales, Australia. A renowned expert in several subfields of mathematics, as well as on cryptologic history, Dr. Donovan has conducted some of the most innovative and path-breaking work to date on the Allied effort to break Japanese encipherment systems in use during WWII. He will be presenting two separate lectures detailing the cipher war in the Pacific, including revelations about the weaknesses in the Japanese naval codes that the Allies exploited, all of which led to dramatic successes on the battlefield.
These talks are free and open to the public. They will be held in the Magic Room of the National Cryptologic Museum. There presentation and specific talks are listed below.
--Thursday, May 23 – 1000-1200: “Understanding the Allied Approach to Radio Intelligence in the Pacific Theatre during World War II”
--Friday, May 24 – 0930-1130: “The Thought Behind High-level Cryptological Discovery, 1930-1945”
