"Composed of Jewish patients, mostly women, Block 10 at Auschwitz was the site of Nazi medical research.
The barrack was known as "Clauberg's Block" after the physician, Carl Clauberg (left), who conducted much of the experimentation there.
Clauberg was especially interested in infertility and sterilization research, areas that won him the personal backing of Heinrich Himmler, who wondered 'how long it would take to sterilize a thousand Jewesses.'
Clauberg used injections, probably of the substance formalin, to cause obstructions in the fallopian tubes and prevent pregnancy."
Could you imagine if we had a daily newspaper archive from the Roman Empire? This kind of daily posting would take decades or more. lol.
