Mr Eschenburg was a German journalist. Mr Eschenburg received nine awards, you will not (yet) find this in Wikidata and had one award named after him; the Theodor-Eschenburg-Preis.
All the information about award winners etc is in the article of the conferring organisation; the Deutsche Vereinigung für Politikwissenschaft. That works fine in Wikipedia but the award is surely not an alias for the award in Wikidata.
When I find such issues, the situation is easily by creating a new item.
NB when you look at the Reasonator page for Mr Eschenburg, check out the long line of notable people he is part of..
