I don't have doctor's name here, will provide it in the evening EST, but there was one doctor who received hundreds of skulls (or heads) of concetration camp victims to use in his research. He published his findings in science literature in 1949.

edit: here is the paragraph from the book, chapter 36:

On March 9, Professor Hallervorden, a German neurologist, wrote to Professor Nitsche, who was in charge of the euthanasia programme: ‘Dear Colleague, I have received 697 brains in all, including those which I took out myself in Brandenburg. Those from Dosen’—a mental hospital near Leipzig—‘are included in this gure. The greater proportion of them have already been studied, but whether I will be able to make a histological study of them all, only time will tell.’ Professor Hallervorden’s method’ was to remove the victims’ brains immediately after they were killed. ‘There was wonderful material among those brains,’ he later told his American interrogators, ‘beautiful mental defectives, malformations and early infantile diseases.’

After the war, Professor Hallervorden continued to use these brains in his researches, publishing the results of one particular case in 1949. Part of his collection later went to the University of Frankfurt.
