You know how things work on the Internet. A search for something in Google displays a link, which leads to another page, which leads to a third, etc. Before you know it, you’ve discovered goldmines you never knew existed.
This past week I searched for “PURPLE” in Google’s image database (I think that’s what I did — it was oh so many link clicks ago :-)). Perusing the booty uncovered a link to a link to a link etc. until I chanced upon some cryptographically-related photo collections on Flickr. I have spent many an hour since enjoying the eye candy there and in other locations. I’d like to share some of these sites with you.
Brewbooks: Trip to the National Cryptologic Museum 13 Feb 2009
This treasure trove by J Brew resides on Flickr, with the cryptologic-related photos beginning here. Get ready for an abundance of “eye candy” by an extremely talented photographer (check out his other photo collections to convince yourself you’re in the presence of a master). The photographs are incredibly clear, allowing you to read book titles, exhibit text, and see precise details of devices.
Mr. Brew (here’s his photo) has kindly provided very descriptive texts for all of the photos, enabling you to learn a great amount of information while feasting your eyes on them. In addition, many of the photos have hotspots: position your cursor over the hotspots for more detailed descriptions. Run it as a slide show for the best photographic clarity.
Here’s a list of photos that caught my fancy:
- Linguists in NSA: impressive biographies of Dr Sydney Jaffe, James R. Child, Norman Wild, and John B. Hurt
- Clear photos of numerous cryptographic devices (e.g., TUNNY, STURGEON, Enigma, and many more machines)
- Enigma daily keys list
- Japanese Navy RED Cipher Machine
- JADE Japanese Cipher machine
- US Navy Cryptanalytic Bombe and M-9 Bombe Checking Machine
- Original (censored!) drafts of David Kahn’s “The Codebreakers”
Brew’s photos of book shelves of the library of the National Cryptologic Museum (starting here) had me salivating. His photos are crystal clear, sharp enough to make out many of the titles, of which I mention those classic texts that caught my eye:

Military Cryptanalytics Part I
Uploaded to Flickr by “Travelin’ Librarian”, these are eight photos from this classic written by Friedman and Callimahos.
Who’s Who in American Cryptology
These photos (by austinmills) constitute excellent biographies of American cryptologic luminaries.
I’m sure this selection of photo collections only touches the tip of the iceberg. As such, I believe they will be of interest to fellow amateur cryptologists.
