Question: Who was elected elected President of Germany in 1925 and whose death led to the referendum on merging the posts of Chancellor and President?
Context: A referendum on merging the posts of Chancellor and President was held in Germany on 19 August 1934, after the death of President Paul von Hindenburg 17 days earlier.
