Carl Værnet

Carl Peter Værnet (April 28, 1893 – November 25, 1965) was a Danish doctor at Buchenwald concentration camp and an SS-Sturmbannführer. Værnet attempted to cure homosexuality by implanting artificial hormone glands into male prisoners at Buchenwald. Although he was arrested after World War II, Værnet fled to Argentina where he practiced medicine until his death. He was educated as a physician at the University of Copenhagen where he obtained his degree of medicine in 1923. His son Kjeld Værnet (1920–1999) was a respected neurosurgeon at Rigshospitalet in Copenhagen.

Heinrich Himmler wrote "treat Værnet with the utmost generosity. I request a report of three to four pages each month because I am very interested in these things". Værnet was relocated to Prague to carry out his research at Buchenwald concentration camp under "German Medicines Ltd". Up to 17 men were involved in the experiment, Little is known about fate of the other victims, as none are known to have applied for financial compensation after 1945.

Værnet claimed that "successes" with the implants occurred, and included excessive praise of Himmler, perhaps in an attempt to distract from his lack of results. Kjeld Værnet twice unsuccessfully attempted to negotiate impunity to allow his father's return to Denmark.
