Memorial to the victims of National Socialist euthanasia crimes, Memorial site in Munich Waldfriedhof, Germany.

The Memorial to the victims of National Socialist euthanasia crimes stands at the Waldfriedhof in Munich, erected by the Max Planck Society on 25 May 1990 at the initiative of its then-president Heinz A. Staab. Its inscription reads: "In memory of the victims of National Socialism and their abuse by medicine. To all researchers as a warning to exercise responsible self-restraint," with the donor named in smaller letters below. Brain preparations from victims, misused by the predecessor institutes of today's Max Planck Institute of Psychiatry, were buried here in 1990.

The memorial was established in 1990 to document atrocities that occurred when the Nazi regime systematically killed people with disabilities and mental illnesses during the Second World War. This grim chapter has long remained overshadowed by other historical narratives.

The memorial was erected by the Max Planck Society on 25 May 1990 at the initiative of its then-president Heinz A. Staab. Its inscription reads: "In memory of the victims of National Socialism and their abuse by medicine. To all researchers as a warning to exercise responsible self-restraint." Smaller letters name the society as donor.

The memorial stands in the Waldfriedhof at Fürstenrieder Straße 288, reachable by tram 19 or bus 51/151 to the Waldfriedhof stop. The grounds open daily, and the memorial itself is an outdoor stone stele with an inscription, so no opening times apply. The path from the main entrance is signposted; the site is not fully step-free, as some cemetery paths are gravel.

The memorial was erected by the Max Planck Society, not by the city, on the initiative of its then-president Heinz A. Staab; the brain preparations of victims used by the Kaiser Wilhelm Institutes were buried here in 1990. The inscription ends with a charge to researchers: to exercise responsible self-restraint.
