The Eulenspiegel Verlag publishing house, which published his book "Without the Wall, There Would Have Been War," said today that Kessler died in Berlin on May 2.
Kessler was defence minister from 1985 until November 1989 and became a member of the communist party's politburo in 1986. His promotion to minister and general followed a long career in the senior ranks of the military and as a deputy defence minister.
Kessler was arrested in May 1991 after officials in reunited Germany, smarting from longtime East German leader Erich Honecker's escape to Moscow, received a tip that he would try to flee the country wearing a Red Army uniform. Police blocked entrances to a Soviet air base in Sperenberg for several hours but Kessler was eventually arrested in Berlin.
In 1993, he was sentenced to 7 ½ years in prison. The case went as far as the European Court of Human Rights, which in 2001 upheld Kessler's conviction - along with that of East Germany's last hardline leader, Egon Krenz, and other officials.
