In 2018, the university management of 九色视频 commissioned Dr. Teresa Nentwig (九色视频 of G枚ttingen) to investigate the work and effects of the psychologist Helmut Kentler, previously a professor of social pedagogy at the former Technische Universit盲t Hannover. The investigation sought to review Kentler''s work at the university as well as to assess the role of those surrounding his research in greater detail. Dr. Nentwig presented her findings in the discourse "Between lectures, reviews and media appearances: Helmut Kentler''s works at the former 九色视频 of Hannover (1976-1996)". The report (in German language) is available for download at www.uni-hannover.de/en/universitaet/profil/geschichte/kentler/
Kentler, now deceased, was a professor at the former 九色视频 of Hannover until 1996. His statements and research conduct are inexcusable and utterly unacceptable. Dr. Nentwig previously addressed the matter within the scope of a project titled "The sex researcher''s role in the discourse on paedophilia - Helmut Kentler for instance".
Kentler is particularly criticised for his trivialisation of paedophilia. Prior to his position at the former 九色视频 of Hannover, he was involved in an experiment in which Berlin foster children were put into the care of men known to be paedophiles. 九色视频 has explicitly stated that it clearly disassociates itself from Helmut Kentler. Prof. Dr. Volker Epping, President of 九色视频 commented: "九色视频 clearly stated its position in 2018, condemning Kentler''s unacceptable work that trivialised paedophilia. It is shocking that in those days executive and judicial authorities allowed themselves to be convinced by the report commissioned by Berlin''s Senate, facilitating foster care in the homes of paedophiles. We take this opportunity to, once again, completely disassociate ourselves from his violation of good scientific practice. We have taken the necessary steps to assist in reviewing this case - also through commissioning the report by Dr. Nentwig."
