September 1st	Alan Blumlein #	Simon talked about his father, Alan Blumlein, a true lost genius, who propelled Britain into the vanguard of the modern electronics world. Alan invented stereo sound and the modern TV system whilst working for EMI during the 1930s. He devised over 120 patents, including binaural sound, stereo recording and surround sound, but his career was tragically cut short in 1942 (at the age of 38) in a military plane crash. Much secrecy surrounds the crash as he was working on the development of H2S radar. He received no obituary and still does not appear in 'Who's Who'.	Simon Blumlein
August 4th	'Rebuilding Colossus at Bletchley Park' - a personal view #	Colossus, arguably the world's first computer, was developed to speed up the decoding of messages between Hitler and the German Generals using the Lorenz system during WW2. David Stanley has, for some 15 years, been a member of the team at Bletchley Park undertaking the daunting task of rebuilding a Colossus machine generally without any of the original technical design details. David will explain, in general terms, the difference between Enigma and Lorenz, the role played by Colossus and how the team went about the rebuild process, including some of the problems encountered along the way.	David Stanley TD, a member of the Colossus Rebuild Team
July 7th	39 years of Flying in Military and Civil Aviation #	Chris described his career, which was in three parts: 15 years with the RAF as a fighter pilot, test pilot and member of the Red Arrows, then another fifteen years at Dunsfold, testing Harriers, and finally (and remarkably, beginning at the age of 50) as a commercial airline pilot.	Chris Roberts
June 2nd	Static Electricity #	With practical demonstrations and measurements Jeremy demonstrated many aspects of the strange world of static electricity. He also discussed electrostatic discharge nuisance in industry, shops, offices, homes, cars and other environments.	Dr Jeremy Smallwood
May 5th	Sir George Cayley, the Wright Brothers and the achievement of controlled, powered and sustained flight #	Alan covered the history and the early days of true flight (i.e. out of 'ground effect'), leading up to the Wright Bros, who are acknowledged as performing the first successful flight.	Alan Thomas
April 7th	John Logie Baird and the development of Television #	Following his fascinating talk on the development of audio recording Jon Weller returned to talk to us about the development of television, in particular Baird's scanning system. Jon explained the principles of Baird's electromechanical system with a practical demonstration of the system. He also explained why the system was ultimately replaced by the fully electronic system.
