The National Museum of the Pacific War presents an oral interview with Harry Longerich. Longerich was born in Germany in 1917 and immigrated to the United States. He attended the Stanton Military Academy and was an amateur radio operator. After opening a successful radio service store with celebrity customers, he sold the business in 1938 and enlisted in the Army in anticipation of the war. He attended basic training and learned CW operation at Fort Monmouth. He was stationed on Hawaii during the attack on Pearl Harbor. Days later, Longerich overheard Admiral Kimmel lamenting the loss so many young men. Because of his fluency in German, he was chosen for several offensive and defensive counterintelligence operations with the Sixth Army, broadcasting false information to Germany leading to a diversion of Hitler’s divisions on the Eastern Front, and attaching an antenna to a balloon to eavesdrop in hard to reach locales. He was so adept with radio equipment that he was called upon to repair Patton’s personal radio, and he hand-delivered eyes-only communications to Eisenhower. He later joined the Army Security Agency as an electronic countermeasures specialist and R&D engineer. After attending Command and General Staff College, Longerich retired in 1963.
