Most of his work at Bletchley was centred on what was known as "traffic analysis" of encrypted German communications.
Most cryptographers agree this is markedly easier than attacking cryptographic ciphers directly although still very complicated and mathematically intensive processing is needed to make initial discoveries , and Welchman is credited with innovating the approach.
This led to data analysis techniques that today we describe as "metadata" analysis.

Some have credited his work with shortening WW11 by 2 or 3 years. His method is still in use and was included in the US search and discovery of Osama bin Laden.

Feb 16, 5. Thanks Max. I checked Wikipedia about Gordon Welchman and found some interesting information and links.

MIT Radiation Laboratory Series
John F. Wheeler Loomis no relation to Alfred Loomis was deputy director for administration. Even before opening, the founders identified the first three projects for the Rad Lab. In the order of priority, these were 1 a cm detection system called Airborne Intercept or AI for fighter aircraft , 2 a cm gun-aiming system called Gun Laying or GL for anti-aircraft batteries, and 3 a long-range airborne radio navigation system.
To initiate the first two of these projects, the magnetron from Great Britain was used to build a cm " breadboard " set; this was tested successfully from the rooftop of Building 4 in early January All members of the initial staff were involved in this endeavor. Under Project 1 led by Edwin M. This, the first microwave radar built in America, was tested successfully in an aircraft on March 27, It was then taken to Great Britain by Taffy Bowen and tested in comparison with a cm set being developed there.
For the final system, the Rad Lab staff combined features from their own and the British set. It eventually became the SCR, used extensively by both the U. For Project 2, a 4-foot- and later 6-foot-wide 1. Also, this set would use an electro-mechanical computer called a Predictor-correlator to keep the antenna aimed at an acquired target.
Getting served as the project leader. Being much more complicated than the Airborne Intercept and required to be very rugged for field use, an engineered GL was not completed until December This eventually was fielded as the ubiquitous SCR , first gaining attention by directing the anti-aircraft fire that downed the about 85 percent of German V-1 flying bombs "buzz bombs" attacking London.
They had an existing hyperbolic navigation system, called GEE , but it was inadequate, in both range and accuracy, to support aircraft during bombing runs on distant targets in Europe. By the end of hostilities, about 30 percent of the Earth's surface was covered by LORAN stations and used by 75, aircraft and surface vessels.
At the height of its activities, the Rad Lab employed nearly 4, people working in several countries. Activities eventually encompassed physical electronics, electromagnetic properties of matter, microwave physics, and microwave communication principles, and the Rad Lab made fundamental advances in all of these fields.

Half of the radars deployed by the U. For the exchange of information, the Rad Lab established a branch operation in England, and a number of British scientists and engineers worked on assignments at the Rad Lab.Horner Kuper.
Smullin and Carol G. Most of the senior staff were Ph. This was made simpler by Lawrence and Loomis being involved in all of these projects. From the forward of each book: The tremendous research and development effort that went into the development of radar and related techniques during World War II resulted not only in hundreds of radar sets for military and some for possible peacetime use but also in a great body of information and new techniques in the electronics and high-frequency fields.
