Time Witness: Klaus-M. von Keussler
Klaus-M. von Keussler (born 1939 in Königsberg / today Kaliningrad) studied law in West Berlin and experienced the erection of the Wall there in 1961. As a 23-year-old, he participated in the construction of several escape tunnels; through one successful tunnel (1964), 57 men, women and children were able to escape to the Western part of the city. He was also involved in several successful individual escape operations and, together with his comrades-in-arms, helped a total of 65 people to leave the GDR. The arrest warrant issued against him in 1965 was lifted in 1985. Today, he is a member of the Ettersberg Foundation's Advisory Council for Coming to Terms with SED Injustice and chairman of the FREIHEIT – Booster Club Andreasstraße Memorial and Education Center Andreasstraße (in the former Stasi remand prison) in Erfurt.
