Papers concerning the work of Dr Johannes Gievers who was one of the leading gyro scientists in Germany during the war. He was captured by the Russians but escaped and though later captured by the Czechs, escaped again and gave himself up to the BNGM, Minden, Germany. By the end of the war he held advanced ideas for an overland compass, based on inertial naviagtion system (INS) principles, but a number of fundamental problems were still unsolved. He also designed a miniature gyro-compass for Midget submarines. He was interviewed by scientist from ACO and AGE and later worked at AGE until he emigrated to America in 1950. He died in 1979.
