Early years From 1922 till 1927 Hamann studied Agricultural Sciences at
Hohenheim,
Bonn and
Berlin. Subsequently he became the head of Employment Offices in
Schwerte,
Hörde and
Dortmund, and, in 1931, of a relocation co-operative in
Thuringia. He was relieved of his responsibilities and expelled from the
LDPD. More than two years of "investigatory detention" at the
Hohenschönhausen Jail followed. In July 1954 he was sentenced, in a secret trial, to ten years in prison, but he was pardoned in October 1956 and let out. In May 1957 he fled to the
German Federal Republic (West Germany).
West Germany Dr. Hamann died in
Munich a couple of months after his seventieth birthday. His grave is in the
Central Cemetery at
Bad Godesberg (Bonn). ==Posthumous rehabilitation and celebration==
