The Aspen Institute

The Aspen Institute and Bonhams 
invite you to a wine and cheese reception and a private viewing of 
an unknown wartime manuscript of the utmost rarity, consisting of 
56 pages of mathematical notes by Alan Turing, in which he works on the 
foundations of mathematical notation and computer science, 
likely the only extensive holograph manuscript by him in existence. 
Also on view will be a 1944 Enigma machine.

With remarks from Walter Isaacson
, president and CEO, the Aspen Institute and author of 
”The Innovators: How a Group of Hackers, Geniuses, and Geeks 
Created the Digital Revolution” (Simon and Schuster).
