Describe Albert Dussel as he appears in Anne Frank’s diary?

Albert Dussel is an elderly dentist who joined Anne and her group in the hiding in November 1942. He and his Catholic wife had emigrated to Holland after the anti-Semitic riots of November 1938. During his hiding in the Secret Annexe, Mr Dussel grew rather difficult and life became uncomfortable and annoying for Anne to share her already limited room space with an old man who was used to showing off his knowledge. Mr. Düssel went with the other members of the group first to Westerbork and then to Auschwitz. He was later separated from the other men in the group and was sent back to Germany. He died at the Neuengamme camp.
