David Kahn

David Kahn (b. February 7, 1930) is a US historian, journalist and writer. He has written extensively on the history of cryptography and military intelligence. Kahn's first published book, The Codebreakers - The Story of Secret Writing (1967), was widely considered to be a definitive account of the history of cryptography up to the mid-1960s. Also, at that point, cryptography exploded into high technology and deep mathematics - impossible for the layman to understand. David Kahn was born in New York City to Florence Abraham Kahn, a glass manufacturer, and Jesse Kahn, a lawyer. Kahn has said he traces his interest in cryptography to reading Fletcher Pratt's Secret and Urgent as a boy. Kahn is a founding editor of the Cryptologia journal....
