Book- Aly, Götz, “Cleansing the Fatherland: Nazi Medicine and Racial Hygenie”,(John Hopkins University Press, England, August 1st 1994). I found this source relevant to a certain extent as it gave me a lot of useful background information about my chosen topic. I learned a lot about the experiments the were done in Nazi Germany during world war II. However it wasnt that helpful with finding out information on my specific doctor.
One strength of this source was that it was it had a clear layout. It has a useful contents page and a helpful bibliograpy. This made it easy to navigate and find what I needed. Another strength is that it is reliable as all the sources of the information in the book are listed in the bibliograpy.
