Prize winner Martinus Veltman who had written the foreword to the Rispen book, renounced the book's description of Peter Debye, withdrew his foreword, and asked the Board of Directors of Utrecht University to rescind their decision to rename the Debye Institute. Various historical investigations, both in The Netherlands and in the US, have been carried out subsequent to the actions of the University of Maastricht. The earliest of these investigations, carried out by the Cornell University's department of Chemistry and Chemical Biology released a report on 31 May 2006, which states that: Based on the information to-date, we have not found evidence supporting the accusations that Debye was a Nazi sympathizer or collaborator or that he held anti-Semitic views. It is important that this be stated clearly since these are the most serious allegations. It goes on to declare: Thus, based on the information, evidence and historical record known to date, we believe that any action that dissociates Debye's name from the Department of Chemistry and Chemical Biology at Cornell is unwarranted. In June 2006, it was reported that the scientific director of the (formerly) Debye Institute had been reprimanded by the Board of Directors of the University of Utrecht for a new publication on Debye's war years on the grounds that it was too personally biased with respect to the Institute's naming dispute. According to the board, the book should have been published not as a Debye Institute publication, but as a personal one. The book was banned by the University of Utrecht and both Directors of the (former) Debye Institute were forbidden to have any further contact with the press. A dozen professors of the Physics Faculty, amongst whom Cees Andriesse, openly protested against the interventions of the Board and the censorship of their protest by the university. In May 2007, the universities of Utrecht and Maastricht announced that a new committee headed by Jan Terlouw would advise them regarding the name change. Also, in the beginning of 2007 an official report was announced, to be published by the NIOD and authorized by the Dutch Education Ministry (then scheduled for fall 2007). 2007 NIOD report The report describes Rispens' presentation of Debye, as an opportunist who had no objection to the Nazis, as a caricature. [I]t can be stated that Debye was rightly called an opportunist after his arrival in the United States. We have seen that he
