GCHQ’s director’s Turing speech – a research team manual?

Just read the speech about Alan Turing, given by Iain Lobban, Director GCHQ, at the University of Leeds.

Fantastic stuff in there. Here are some excerpts.

On learning to solve problems

“… [Turing] reported to Bletchley Park as agreed and immediately started working with [Dilly] Knox [expert on the Enigma cypher …]. Knox’s influence on Turing at this time is immense. The older veteran cryptanalyst shared everything he knew about Enigma with Turing, who eventually used this knowledge to write the first four chapters of his treatise on Enigma […]

“…[Turing] was happy to learn from Dilly Knox, happy to use that knowledge as the foundation for what he would develop subsequently, and was diligent in recording what he had learned and how he developed that into new areas so that others could profit from his knowledge just as he had profited from that of Knox.”

Knox could only take Turing so far and his quest for experience-based understanding of the cryptanalysis of Enigma took Turing to France in January 1940…”

Team work

There are lots of different ways in which people can work as part of a team.  Turing’s way was to take in other people’s ideas, develop and build on them, and then pass the product on to other people to be the foundation for the next stage.  He took the idea of electromechanical processing of Enigma messages from the Poles but developed their idea into something radically different.  When Welchman later enhanced the Bombe with his diagonal board, Turing was among the first to congratulate him on this major improvement.  Turing was part of the team, and shared in the success of the team.”

Respecting diversity

“I strongly believe a Sigint agency needs the widest range of skills possible if it is to be successful, and to deny itself talent just because the person with the talent doesn’t conform to a social stereotype is to starve itself of what it needs to thrive.”

“I don’t want to pretend that GCHQ was an organisation with twenty-first century values in the twentieth century, but it was at the most tolerant end of the cultural spectrum.  In an organisation which valued the skills and characteristics that difference can bring, Turing’s homosexuality was less of a talking point than his insights into the complex crypt problems of the day.  When he was put on trial, Hugh Alexander, the Head of Cryptanalysis at GCHQ went, with official approval, to speak as a character witness on his behalf, saying in court that Turing was a national asset.”

Exploiting serendipity

“Geoffrey Tandy was posted to Bletchley by the Admiralty in a spirit of helpfulness: his posting officer had understood him to be an expert in cryptograms, a word still used in the Admiralty at that time to mean messages signalled in code.  In fact he was an expert in cryptogams: non-flowering plants like ferns, mosses and seaweeds.  But while this knowledge might not have appeared to be of much use, Tandy became expert in German naval Enigma and because of his work on seaweed was able to provide unique advice on the preservation of cryptologic documents rescued from the sea.”

The role of management

“Part of my job is to continue to foster that atmosphere: to attract the very best people and harness their talents, and not allow preconceptions and stereotypes to stifle innovation and agility.”
