Signal Corps RADAR Ready and Operating December 7, 1941 Thanks to Camp Engineers such as Mr. Marchetti

On January 9, 1999 Mr. Marchetti returned to Camp Evans to provide an oral history for our research and archieves.  He was with his daughter Mrs. Nina Archabal.  This gentleman's accomplishments are documented in many books and many a WWII G.I. are alive today thanks to his radar expertise and leadership.  Mr. Marchetti (left) is in front of building 9020 where he and twenty others assembled the radar kits for the worlds first mortor locating radar during WWII.  The story is documented in Dr. Zahl's book available on this site.  Mr. Marchetti stood during the entire hour interview.  Answering question after question as if the events occured last week.  A few months after this interview Mr. Marchetti was awarded a medal from France for his participation in D-Day and the liberation of France.  He adds this to the prestigious 'Order of the British Empire' award from England for his anti-V1 and V2 radar work.

John Marchetti, 90, Cherry Hill, was one of a small group of scientists who labored at Camp Evans in a top secret laboratory during the 1930s and '40s on electronic equipment that not only affected course of the war, but would find many peacetime uses

     Wall - The Japanese attack on Pearl Harbor, Dec. 7, 1941, which brought the U.S. into World War II, could have had an entirely different outcome had the defenders made proper, use of a unique electronic device they had at their disposal.
     That's one of the disclosures made Saturday by one of the scientists who developed that very versatile equipment, which would change forever the conduct of warfare and many peaceful pursuits -- radar, an acronym for radio detecting and ranging.
     John Marchetti, 90, Cherry Hill, was one of a small group of scientists who labored at Camp Evans in a top secret laboratory during the 1930s and '40s on electronic equipment that not only affected course of the war, but would find many peacetime uses.
     Marchetti came to  Camp Evans in 1937 as a junior radio engineer, shortly after completing his graduate studies at Columbia University, N.Y., in electronic engineering.
     Marchetti was here being interviewed for a "living history" of the post by Fred Carl, Wall, who is leading a fund-raising campaign to restore some of the camp's permanent buildings such as the, "Marconi Hotel," the brick structure facing, Marconi Road where the wartime scientists worked.
Carl hopes to convert the historic site to a "hands on" electronics education center for area youths.
     Marchetti said he was "furious" when he learned of the Pearl Harbor debacle which, in addition to the death and destruction it caused, seriously, crippled the Navy's Pacific Fleet for many months to come.
     What was disturbing to him, Marchetti. said, was the later disclosure that U.S. Air Corps Radar operators had detected the incoming Japanese aircraft when it was still some 200 miles out and reported that fact up through the chain of command.
     That would have given the defenders more than an hour to react to the impending strike, he said, sufficient time to scramble U.S. fighter aircraft from island bases to intercept, and ample enough for the activation of the substantial ship and ground based anti-aircraft defenses.
     Why the warning never got to the high command is not known. The result was the destruction of most of the U.S. aircraft on the island and serious damage to the fleet.
     Had the U.S. Forces deployed, Marchetti said, they would have had a better than even, chance of destroying the Japanese and thus changing the entire subsequent course of the war, especially in the Pacific Theater.
     Marchetti said the radar in Hawaii at the time was the SCR-270 100 megacycle set, developed by his team at Camp Evans, under the command of Maj. Paul Watson, another of the pioneers.
     Shortly after the start of the war, Marchetti said he and the other scientists were "furloughed to the service." He became a captain in command of a company.
     During this service, he said, he traveled throughout the world, providing electronic assistance to virtually every U.S. service component and some to Allied forces.
     He helped British radar operators to better detect incoming German V-1 jet-propelled "buzz bombs," increasing the anti-aircraft kill ratio for the destructive bombs from 0 to 85 percent.
     Later, in -Europe and in the Pacific area, he said he helped developed radars to quickly detect enemy mortar positions which were causing many casualties among U.S. personnel.
     After his discharge from the Army, Marchetti served as technical director of Radio and Physics Research at the U.S. Air Force Cambridge Research Center in Mass.
     Resigning from government service in 1954, Marchetti went into private industry as an electronics consultant.
 
 Webeditors note:  Dr. Marchetti started his career in 1937 at main post Fort Monmouth, then was instramental in the radar development at Fort Hancock, Sandy Hook, NJ.  His work at Camp Evans was done in 1941 and later.

Dr. Marchetti related another story from Fort Hancock.  He was working with his team in the hot summer sun in his undershirt.   He was a "hands-on" and take charge person.  A visiting officer came by to observe the progress who proceeded to lecture Dr. Marchetti on proper military dress for officers and how he show assign the work and not be in the middle of it.  Dr. Marchetti politely reminded the officer a war was coming and dress code or not they would all be in the middle of it.
