In the 1984 film amadeus based on wolfgang mozart's life, wolfgang is commonly referred to as wolfi, especially by his wife (as spelled in the scripts i could find online). Is there any source that describes why? This question is too basic
It can be definitively answered by a single link to the relevant topic on wikipedia or another standard reference source Wikipedia states, that the city of salzburg (austria) was called „stadt der lebensforschung“ as honorary city title
