development on the border was accessible only under strict access restriction. Hans-Jürgen Starrost, Klaus Garden and Roland Hoff were killed by the GDR while attempting to escape from Teltow to West Berlin. An important event for the development of Teltow in January 1946 was the founding of Askania Feinmechanik und Optik GmbH, which developed systems for the automation of industrial processes. 1948 Askania was like all larger enterprises in national property VEB mechanics Askania Teltow transferred and renamed 1954 into VEB equipment and regulator works Teltow (GRW Teltow). In 1962, the GDR’s Economics Council granted GRW Teltow nationwide responsibility for the operating, measuring and control technology (BMSR technology) in the GDR. The company grew to about 12,000 employees in the 1970s and was the center of automation technology in the GDR. The second large industrial enterprise in Teltow was the VEB electronic components "Carl v. Chr. Ossietzky "(CvO), which resulted from the transfer of the Dralowid work in 1948 in VEB Dralowid and the renaming in 1953 in VEB work for components of telecommunications" Carl von Ossietzky "(WBN). By 1955, 30 million sheet resistors were produced by hand each year. The production number could be increased to three million resistances per day in the following decades until 1989. In the WBN 1951 started the starting signal for the structure of the new industry branch semiconductor technology in the GDR with first research work to semiconductors. Under the direction of Matthias Falter, the employees of the WBN research department produced the first samples of high-end transistors in 1953. Urban planning of the 1960s resulted in the almost complete demolition and redevelopment of Teltow’s downtown. Only the church, the cinema and a part of Kuppelmayrschen settlement was preserved. In the 1980s, planners in Teltow began a process of rethinking. Initially, individual objects were listed as historical monuments, and in 1986, parts of the old town were declared area features. Accompanying the development of industry new areas for housing were developed and developed: 1961 to 1965, the Neue Wohnstadt, 1970 laying the cornerstone for the residential complex Bodestraße in the river district; 1987 to 1989, the residential area Ruhlsdorfer Platz, 2005, the musicians quarter, 2006, the construction field mill village with the final expansion possible 442 single-family, double and terraced houses. At the end of 2008 Teltow had 21 residential areas. The present municipality was established in 1994 by the merger of Teltow
