Dr A C Bishop talking about Dr Klüpfel, the german geologist who was conscripted to Jersey in August 1941, to the Channel Islands Occupation Society. Klüpfel studied the geology of the island druring the occupation and assited the German forces in the siting and building of tunnels and strongpoints.His notebooks were discovered in the 1970s and much information were gained from theseat the Institute of Geological Sciences. Dr Klüpfel wrote predominately geology in notebooks but also scraps of military information. He was billeted in room 80 at the Grand Hotel. A number of different topics in the islands were investigated by him. Sand and gravel were needed for concrete and he made a surveys of beaches of the island to estimate how much sand and gravel could be taken. Coastal studies included most of beaches of the island and record very accurately the composition and size of gravel. Klüpfel visited most of the quarries in the island and wrote about the potential of each. He suggested possible sites for the Organisation Todt camps in the North of Island and investigated whether enough water would be available to house the OT workers. Early 42 first mention of the power station at Tesson Mill-needs discussed by Dr Klüpfel. Studied tunnels in the island.Especially involved in those of St Peter's Valley, Mushroom Tunnel, German Underground Hospital, Grands Vaux and St Aubin's tunnels. Lists firms involved in drilling in Channel Islands. Wrote reports on tunnels. Military installations sited according to military and not geological thoughts (bad quality of recording). Need for water at strongpoints and Klüpfel looked at the needs for different sites. Drainage problems of camps and strongpoints. 23rd April 1944 last dated entry. Unknown when he left the island. Next heard of in 1946 in post war correspondence. Bishop states he had a big affect on defences in Channel Islands. Questions and answers at close of speech.
