The Swiss descendent of one of Adolf Hitler’s doctors has released details of letters that show how he treated the Nazi dictator for voice problems, NZZ am Sonntag newspaper reported yesterday.

Hitler was treated several times by Carl Otto von Eicken, a German ear, nose and throat specialist, for 10 years from 1935, the newspaper said.

The letters from the doctor to a cousin were discovered by Robert Doepgen, von Eicken’s great-great-grandson, who found them when researching family archives for a school project. Von Eicken died in 1960.

British historian Richard J Evans, a specialist in German history, vouched for the authenticity of the unpublished letters, the newspaper said.

The letters show Hitler’s fear of serious illness, it said.
