Heinz Kessler or Heinz Keßler (26 January 1920 – 2 May 2017) was an East German communist politician, military officer and a convicted felon. He is known for his role in political repression in East Germany prior to the communist regime's downfall in 1989.

In East Germany, he held the rank of Armeegeneral in the National People's Army (Nationale Volksarmee) and was Minister of Defense of the GDR, a member of the Politbüro of the Central Committee of the Socialist Unity Party of Germany (SED), and a deputy of the GDR's Volkskammer (parliament).

Convicted for his role in the crimes of the communist regime, he was sentenced to seven-and-a-half years in prison after German reunification, and served his sentence in Hakenfelde Prison. He was released from prison in 1998 after serving only two years.

Biography

Kessler was born into a communist family in Lauban, Lower Silesia. He joined the Red Young Pioneers, the youth organization of the Communist Party of Germany (KPD), at age 6. He later apprenticed as a motor mechanic.

Drafted into the Wehrmacht in 1940, he deserted to the Soviet Red Army shortly after the German invasion of the USSR. Upon returning to Germany in 1945, Kessler joined the KPD in the Soviet occupation zone, which merged with the Social Democratic Party (SPD) in the Soviet zone in 1946 to form the SED. Also in 1946, Kessler became a member of the SED Central Committee.

He was appointed Chief of the Air Forces and Air Defense (Luftstreitkräfte/Luftverteidigung) of the NVA in 1956, and as deputy minister of defense in 1957. He became Chief of the NVA Main Staff (Hauptstab - General Staff) in 1967, with the rank of Generaloberst (Colonel General). Simultaneously, he also became a member of the Military Council of the United High Command of the Warsaw Pact.

Kessler was promoted from Chief of the Main Political Administration (Chef der Politischen Hauptverwaltung) of the NVA to Defense Minister (with the rank of Armeegeneral) on 3 December 1985 after his predecessor, Armeegeneral Heinz Hoffmann, died of a heart attack.

Shortly after German reunification on 3 October 1990, Kessler was tried in a German court for incitement to commit intentional homicide, for his role in the deaths of people who tried to flee the GDR between 1971 and 1989. On 16 September 1993, Kessler was found guilty of manslaughter and was sentenced to seven-and-a-half years in prison.

Kessler filed an appeal to the European Court of Human Rights, claiming that his actions were in accordance with GDR law and meant to preserve the existence of the GDR. However, his appeal was denied largely on the basis that the GDR's policies violated international human rights.

Kessler served his sentence in Berlin-Hakenfelde prison from November 1996 to October 1998, and was released early.

Kessler was expelled from the Party of Democratic Socialism in 1990. In 2009, he joined the German Communist Party (DKP). He was a DKP candidate in the Berlin state election, 2011. Kessler died 2 May 2017 at the age of 97.
