Electric and Radio Notes for Wireless Operators (Owned Signal Corp engineer for WWII Normandy Invasion)

His Majesty's Stationary Office, London, 1943. Softcover. Very Good Condition. Book Signed by person(s) connected with book. At first glace, this is a pretty standard WWII technical publication: Air Publication 1762, first issued in 1939, printed in 1940 and then reprinted in 1943. At closer inspection, it is signed in red pencil by its owner:  A. H. Sullivan Jr. / CAPT. S.C. U.S. Army / 9 June 43 -- and therein lies its significance as an artifact belonging to the officer who discovered a glitch that, left uncorrected, could have disrupted the invasion of Normandy on D-Day. According to his profile in the Winter 1977 IEEE Electromagnetic Compatibility Group Newsletter, Aaron H. ("Sully") Sullivan, Jr., almost exactly a year after he put his name on this manual, was "head of the Radar and Radar Countermeasures Section at SHAEF (Supreme Headquarters, Allied Expeditionary Forces)" and "took part in one of the first EMC studies (Project FEELER) when it was found, shortly before D-Day for the Normandy invasion, that severe mutual interference could be expected between various Allied radar and VHF systems which would be operating for communications and aircraft warning in the invasion area. Project FEELER tests and calculations in England prior to the invasion . . . resulted in an amendment to the Signal Annex of the Operation OVERLORD invasion plan. Later in the war, he became Head of electronics intelligence at Headquarters U.S. Air Forces in Europe and after the war led the Air Force investigation into German electronics systems, equipments and components" (p. 9). After the war Sully retired with a rank of Lieutenant Colonel and went on to become a founding member of the Professional Group on Radio Frequency Interference (PGRFI) (now the Electromagnetic Compatibility Society of the Institute of Electrical and Electronics Engineers). He is also credited with coining the term "avionics." Sully died in 1985; his ashes are in a niche at Columbarium No 1 in Arlington National Cemetery. Includes a copy of the 1977 Profile. 221 pages.
