One of the more interesting conclusions of Marks is that different cognitive types require different kinds of instruction in crypto techniques ---some learned rote behavior, some needed reasons. One of the more poignant parts of his memoirs is that he knew that half his pupils would be dead soon after dropping. Another is his worries when trying to figure if someone behind the lines had been compromised (and their directions should not be followed) or they are merely forgetful or stressed. He would refer to their records during study, to see the kinds of errors they made, to help him decide. A very very good book. .... Unbeknown to the latter, Marks had already cracked General de Gaulle's private cypher in a spare moment on the lavatory. -from the obit of Leo Marks, cryptographer --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
