Helmut Becker was born in Trautenau (Bohemia) in 1944. He studied physics and geosciences at Munich University from 1965–1971 and received his diploma in geophysics on the topic of magnetometry in Iceland and started a second study of archaeology at Munich University in 1973–1979. In 1978 he wrote his dissertation in geophysics about magnetometry over the neo-volcanic zone in Northeast-Iceland for the evaluation of seafloor spreading. From 1977–1982 he directed the research project «Archaeo- Prospection and Archaeomagnetism» at the Volkswagen Foundation at the Geophysical Institute of Munich University, establishing a laboratory for archaeomagnetic dating and the development of geophysical prospecting methods (mainly cesium-magnetometry). From 1982–2006 he worked at the Bayerisches Landesamt für Denkmalpflege (BLfD), where he established a laboratory for digital processing of aerial photos and geophysical prospection following the work of Scollar. At BLfD he acted as the director of the Department «Archaeological Prospection and Aerial Archaeology». He became a member of the German Archaeological Institute in 2001. He retired from BLfD in 2006 and in 2007 he founded «Becker Archaeological Prospection ». Helmut Becker is still actively promoting caesium-magnetometry and is working all over the globe. Some of his main prospecton projects include the detection of the Lower City of Troy, Demircihüyük, Bogazköy, Sirkelihüyük (Turkey), Assur, Uruk (Iraq), Palmyra, Resafa, Munbaqa, Tall Bazi (Syria), Awsan- Hagar Yahir, Mahrib (Yemen), Ras al Jinz, Ras al Hadd (Oman), Dashur, Giza, Saqqara, Qantir-Piramesse, Luxor (Egypt), Suchanica, Cicah, Tuva (Sibiria), Tekirbay Depe, Togolog (Turkmenistan), Sazargan, Kefir Kala (Uzbekistan), Sarasm (Tajikistan), Uivar, Cornesti- Iarcuri (Romania), Durankulak (Bulgaria), Vale de Rodrigo, Monte da Ponte, Alcalar, Perdigoes, Xancra, Moreiros2, Monte do Olival, Carascal (Portugal), El Argar, Ambrona, Cerro de la Virgen, Navarra-Los Cascajos, Metallana, Fuente Salina, Paredes de Nava (Spain), Aiali, Ascoli Satriano, Fabrateria, Ostia, Pantelleria, Ravenna Classe, Vale Celone (Italy), Hindwell Neolithic enclosure (Wales, GB), Sigiriya, Dambula (Sri Lanka), Lothal (India) and Neolithic city of Liangzhou and Wah ze Gang – residence of Emperor Qin ze huang di (China).
