Computers at War

November 11, 2020

As has been the case since the onset of COVID-19, this meeting will be via Zoom teleconference (connection details below).

Presenter: Bob Walker, OPCUG

In honour of the November OPCUG Meeting being on Remembrance Day, we’ll look at how the development of early computers was brought about by World War Two. In particular we will be looking at the codebreakers of Bletchley Park like computer pioneers Alan Turing, Gordon Welchman, Tommy Flowers and Max Newman who developed Colossus, the world’s first programmable, electronic, digital computer, and used it to break the German Enigma codes and shorten the war by two years. We’ll also look at some of the other computer developments related to the war and how some of it led directly to the development of the Internet.

The Zoom link will be live at 7:20 pm. Join us at
