The weekend of September 21 and 22 will see what promises to be the largest meeting of slide rule collectors ever held.
The 18th International Meeting of Slide Rule Collectors is being hosted by the UK Slide Rule Circle (UKSRC) at Bletchley Park and The National Museum of Computing (TNMOC) on the Bletchley Park site.
Delegates from nine countries including Australia and the USA will be joining the UK contingent for this prestigious event. On September 21 there will be a formal meeting held in the Mansion, Bletchley Park and on the following morning delegates have the opportunity to explore Bletchley Park and learn about the thousands who made a significant contribution to the codebreaking achievements during World War Two.
In the afternoon delegates will visit TNMOC with its impressive collection of computers focusing on the British contribution to the development of these machines from their earliest days up to the present.
As part of The National Museum of Computing the UKSRC sponsors a small display of miscellaneous slide rules, those calculating instruments that were used universally in aircraft design up until the 1970s, and were indispensable to the American space programme, to tax collectors.
For over 350 years they were the principle calculating tool until the introduction of the electronic calculator made them redundant virtually overnight.
