Paul Reckzeh (4 November 1913 in Berlin – 31 March 1996 in Hamburg) was a physician and Gestapo spy who at the end of 1943 betrayed the members of the Solf Circle, which he had joined while claiming to be a Swiss doctor. His betrayal led to the imprisonment and death of many Solf Circle members. Early life and education Reckzeh was born in 1913, the son of medical professor Paul Reckzeh. He studied medicine from 1933 to 1939 and at the age of twenty, became member of the NSDAP. After he graduated from his studies in 1940, he was made an assistant doctor at a hospital in Birkenwerder. He also worked for the Reichsärztekammer and at the Reichsministerium für die besetzten Ostgebiete. In 1944 he became a Stabsarzt (Staff Surgeon) in the Todt Organisation. Since 1943 he had been working as a spy for the Gestapo, code named "Robby" and serving under Herbert Lange. In August 1943, he received an assignment to go to Switzerland to ascertain what kind of contacts German emigrants had with the Allies. It was through this work that he became aware of and made contact with members of the Solf Circle.
