Given her parent's insistence upon good manners, she would have called him "Mr. Pfeffer" of "Dr. Pfeffer". When she came up with pseudonyms for all those in the annex (not used past the first editions of the diary in publication) she gave his the pseudonym "Dr. Dussel" German for "Dr. Jerk".
Mr. Dussel, a character mentioned in The Diary of Anne Frank, was actually the dentist Fritz Pfeffer. Pfeffer had one child, named Werner Peter Pfeffer.
Mrs. Van Pels and Mr. Pfeffer
Mr Dussels actual name was Fritz Pfeffer. Anne Frank named him Dussel, a German word for nitwit.
His name in the diary is Mr. Albert Dussel... his real name is Friedrich Pfeffer :)
His name was Fritz Pfeffer, and he was a dentist. In the early editions of the diary, he is given the pseudonym "Alfred Dussel".
"Mr. Dussel" was Annes sarcastic pseudonym for Fritz Pfeffer, a dentist and jaw surgeon whom the Franks and van Pels took into hiding about four months after they "disappeared". Pfeffer was very pedantic, stubborn and impatient with young people - he and Anne were constantly at odds. That is why Anne gave him the pseudonym "Dussel", which is German slang for a "jerk".

his real name is Fritz Pfeffer, but Anne gave him the pseudonym Dussel because it is German for silly, ninny, boob, twit etc. and to protect his identity so that he would not be embarrassed if he survived.

Alfred Dussel was Anne's pseudonym for Fritz Pfeffer, a dentist who was in hiding with the Franks. Anne and Pfeffer did not get along - to put it mildly - and anne gave him the name "Alfred Dussel" in her manuscript. "Dussel" is the German word for "jerk".
