Posthumous Testimony for Dr. Leo Gross and his Family / Restoration of the 'Lost' Biography of a Physician Victim of the Holocaust

At a time when the last direct witnesses of the Holocaust are passing, new approaches to the restoration of 'lost' biographies of victims need to be considered. This investigation describes the potential of an international collaboration including surviving family members. Archival documents discovered in Jerusalem in 1983 concerned a discussion on the cancellation of a medical licence for a German Jewish physician, Dr. Leo Gross of Kolberg, who had been disenfranchised from medical practice under Nazi law. After applying for a medical licence during a 1935 visit to Palestine, Gross remigrated to Germany, where he was imprisoned in a concentration camp. No further information was found until 2014, when a group of scholars linked a variety of archival and internet-accessible sources and located a nephew of Gross. The nephew's testimony, cross-referenced against data from other sources, enabled the reconstruction of the 'lost' biography of his uncle and family, in fact a posthumous testimony. The resulting narrative places Dr. Leo Gross within his professional and social network, and serves his commemoration within this context of family and community. The restored biography of Dr. Leo Gross presents an exemplary case study for the future of Holocaust testimony.

The victims of unethical human experiments and coerced research under National Socialism.

There has been no full evaluation of the numbers of victims of Nazi research, who the victims were, and of the frequency and types of experiments and research. This paper gives the first results of a comprehensive evidence-based evaluation of the different categories of victims. Human experiments were more extensive than often assumed with a minimum of 15,754 documented victims. Experiments rapidly increased from 1942, reaching a high point in 1943. The experiments remained at a high level of intensity despite imminent German defeat in 1945. There were more victims who survived than were killed as part of or as a result of the experiments, and the survivors often had severe injuries.

"History had taken such a large piece out of my life" - Neuroscientist refugees from Hamburg during National Socialism.

Approximately 9,000 physicians were uprooted for so-called "racial" or "political" reasons by the Nazi regime and 6,000 fled Germany. These refugees are often seen as survivors who contributed to a "brain drain" from Germany. About 432 doctors (all specialties, private and academic) were dismissed from the major German city of Hamburg. Of these, 16 were Hamburg University faculty members dismissed from their government-supported positions for "racial" reasons, and, of these, five were neuroscientists. In a critical analysis, not comprehensively done previously, we will demonstrate that the brain drain did not equal a "brain gain." The annihilation of these five neuroscientists' careers under different but similar auspices, their shameful harassment and incarceration, financial expropriation by Nazi ransom techniques, forced migration, and roadblocks once reaching destination countries stalled and set back any hopes of research and quickly continuing once-promising careers. A major continuing challenge is finding ways to repair an open wound and obvious vacuum in the German neuroscience community created by the largely collective persecution of colleagues 80 years ago.
