[1] Siemens was born on 4 February 1945 Thüringen, Germany.
From 1969 to 1979 Siemens also taught art at a secondary school in Cologne.
Until 1984 he lived and worked with short breaks in Paris, the south of France and Morocco.
In 1984 the Bundesverband Bildender Künstler created a retrospective display of Siemens' artwork.
The change in the environment and the death of his father left him doubting his painting.
