Hugo Blashke (1881-1959) ran a private dental clinic in Berlin. After treating Hermann Göring in 1931, he was recommended to Hitler – who subsequently appointed him as his personal dentist. Blashke also treated other bigwigs, including Heinrich Himmler, Eva Braun and Joseph Goebbels. He joined the SS in 1935.
Here is confirmation of his promotion to SS-Obersturmbannführer, hand signed in black ink by Himmler, and dated on Hitler’s birthday, 20 April 1937. Himmler was in Berlin on this day, and was snapped standing with Hitler during the birthday celebration parade.
In April 1945, Blashke and other inner circle members, including Dr. Theodor Morell, Albert Bormann and Hitler’s secretarial staff managed to successfully flee the Russians who were closing in on the Führerbunker. Blashke would be arrested by the Americans a month later and imprisoned until December 1948. He opened a small dental practice in Nuremberg and later went on to reconstruct Martin Bormann’s dental records from memory – enabling Bormann’s skeletal remains to be identified in 1972.
