Geneticists in Germany on Monday marked the 75th anniversary of the "Prevention of Progeny with Hereditary Diseases Act," by condemning the euthanization of thousands of handicapped people during the Third Reich.

The forced sterilization and euthanasia program developed as a consequence of the "law to prevent hereditary diseased offspring," which was enacted on July 14, 1933 and was based on the controversial theory that one could improve the human race through selective breeding.

Meanwhile, the hunt for one of the doctors believed to have taken part in the systematic murder of thousands of people during the Third Reich has heated up. Representatives from the Simon Wiesenthal Center (SWC) were in Chile this week to announce its new ad campaign for Operation: Last Chance.

The campaign aims to ensnare Aribert Heim, known to some as "Dr. Death" from Mauthausen, who's been on the run since 1962 when he was tipped off about his imminent arrest. The 94-year-old Austrian served as medical doctor at the Sachsenhausen, Buchenwald, and Mauthausen concentration camps. At Mauthausen, he murdered hundreds by administering lethal injections during the fall of 1941.
