At the Falkenstein Printing House in Klingenthal he received his printer's diploma. In 1955, based on an appeal of the Union of Free German Youth, he entered the National People's Army of the GDR and was enlisted as a cadet at the Franz Mehring Higher Air Force Officer School. After graduation in 1958, he served with the Air Force of the National People's Army of the GDR. In 1970, he graduated from the Gagarin Air Force Academy in the USSR, and continued service in the Air Force of the GDR as a pilot-inspector. Fluent in Russian, he translated into German a number of Soviet military and political publications.

In 1976 he was accepted into the Soviet cosmonaut unit (1976 Intercosmos Group # 1) together with Eberhard Koellner.

He made his space flight from August 26 through September 3, 1978, as the research cosmonaut of the space ship Soyuz-31 (call sign - Yastreb-2) together with Soviet Valery Bykovsky. The cosmonauts worked onboard the orbital complex Salyut-6 - Soyuz -29 - Soyuz -30 together with Vladimir Vasilyevich Kovalenok and Alexsander Sergeyevich Ivanchenkov. Their stay in space was 7 days 20 hours 49 minutes and 4 seconds.

After the flight he returned home to continued service in the National People's Army of the GDR. From 1980 to 1983 he was the Assistant to the Chief of the Directorate of the GDR Air Force.
