As the obit. mentioned, Kahn's papers were deposited at the National Cryptologic Museum at Fort Meade, MD. I had occasion to use them for my research on the history of GPS. I have to commend the NSA for their willingness to allow the public such resources on
code breaking.</div>

<p class="x_MsoNormal"><span style="">Hi Jonathan:</span></p>
<p class="x_MsoNormal"><span style=""> </span></p>
<p class="x_MsoNormal"><span style="">Many thanks for posting the David Kahn obituary. He and I had been friends for over fifty years, and I owe him a particular debt for the great help he gave me by interviewing I.J. Good for me when I was researching the
Colossus in the 1970s. So I feel his loss very personally.</span></p>
<p class="x_MsoNormal"><span style=""> </span></p>
<p class="x_MsoNormal"><span style="">I will always remember the time, many years ago, when David invited me to his home on Long Island for the weekend. At the last moment he apologetically asked me if I minded spending the night at his parent’s house, because
David and his wife had another unexpected guest and had no room for me. When I arrived he took me to a splendid huge house fairly near to his, and I met his father – an impressive and forceful lawyer. His father was very friendly and hospitable to me, though
he made it clear that he thought David ought to be pursuing a more lucrative career than journalism (and cryptology).
</span></p>
<p class="x_MsoNormal"><span style=""> </span></p>
<p class="x_MsoNormal"><span style="">David showed me his cryptology library in his parents’ home on the evening of my arrival – he had no room for it in his own house. He urged me to explore it the next morning while I was awaiting his coming to collect me,
which I of course did. One of the items I found on the many yards of shelving was a large old-fashioned book-shaped metal ledger box. On opening it I found a pile of bound reports, on top of which was a typed letter to David, from William Friedman, the famous
cryptologist. It evidently dated from when David was a schoolboy and was a reply to a request from David. The letter congratulated David on his evident enthusiasm for cryptology and told him that he didn’t need to spend the money he’d been given for a bicycle
on the cost of purchasing one of Riverbank Reports. Instead he, Friedman, was sending David a complete set of these reports! (I’ve just checked and found – predictably – that these famed reports are detailed in a Wikipedia entry -
<a href="https://en.wikipedia.org/wiki/Riverbank_Publications" originalsrc="https://en.wikipedia.org/wiki/Riverbank_Publications" shash="YKIWxc4BO6b2nwMXDVi7Qa30y+FH/Y3GeTbrXZm2SHUVjotzKgdS6UVTgeTSPu7pS0o6EibV7kHm7Ik0YtJIoH0EHuGYncvsUBX4qf1aA3GU9rw7B3R1p8f3R7dBMn7xZZnWWpAk0/gCBBiYUGa+ZP1OSS6V/j7x7OqXJgIeh3U=">
https://en.wikipedia.org/wiki/Riverbank_Publications</a>.) </span></p>
<p class="x_MsoNormal"><span style=""> </span></p>
<p class="x_MsoNormal"><span style="">With this sort of encouragement, from such a source, it is no wonder that David spent much of the rest of his life authoring a set of splendid books on cryptology. And it is great to learn, from the obituary, that David’s
library is now housed at the NSA’s National Cryptologic Museum.</span></p>
<p class="x_MsoNormal"><span style=""> </span></p>
