Interesting grouping of three typed letters sent to the Buchenwald concentration camp regarding medical issues of various prisoners. The first letter is on University of Jena Hospital letterhead, 1p. 4to., Aug. 24, 1942, Jena, reads in part: ‘...We recommend using yellow mercury ointment on the inmate Franz Leitner and wearing safety glasses...Matthias Schneider has [not] recently recovered from trachoma. Inmate Ferdinand Spann has bullous keratopathy as a result of the green star [glaucoma] in his eye...recommend immediate admission to our clinic...’. The second document on Sachsisches Serumwerk letterhead, 1p. 8vo., May 15, 1941, Dresden, notifying the camp doctor of Buchenwald that dysentery vaccines were delivered today and will be followed by instructions from the SS Sanitary Office. The final letter is sent from Buchenwald’s camp doctor to the Hygiene Institute of the SS Main Sanitary Office in Berlin, 1p. 8vo., July 21, 1941, and reads in part: ‘...143 stool samples are sent from prisoners...with a request to be examined for pathogenic intestinal bacteria. It is noted that all prisoners have been vaccinated against typhus and dysentery...’. Concentration camps were a breeding ground for disease due to the lack of food, water, a clean environment, etc., and illnesses such as typhus, dysentery, and even the eye disorders (mentioned in the first letter) were a constant in the lives of prisoners.
