This portrait was made by Robert Fuchs (signed R Fuchs Im Felde 1917) I found it in Hungary some years back. So far I have not been able to establish who this officer is.
Robert Fuchs, “Kriegsmaler”
During the first worldwar the Austro-Hungarian empire used artist to make professional paintings of the war. Not only local but also foreign artists, even a quite famous Dutch artist acted as such, but that is a different story alltogether. These painters did not become part of the army but were paid by it for their services, they were called war painters or in German Kriegsmaler. Sometimes they were attached to a specific unit or a theatre of war.
Robert Fuchs, born in 1896 was such a painter. After the war he went on to become a fulltime professional artist after completing his studies on the Viennese Academy for the Arts. Despite specializing in portraits one of his most famous paintings became the official painting for the 1955 Austrian State treaty pictured below:
Austro-Hungarian officer – R. Fuchs 1917 Im Felde
This portait is of a still unkown officer. Based on the awards he was quite successful in the war with at least an Austro-Hungarian Iron Crown order 3rd class. (first and highest award of the row of ribbons) which is quite rare for a mere captain. The other ribbons are of generic issue for war related medals. Probably one Military Merit cross 3rd class and two Military Merit medals, both the bronze and the silver version. Next to this he has two ribbons in the button hole. One is clearly for the German Iron Cross second class. The second probably is for the Turkish War medal. Those Iron Crescents are most often seen being worn on the breast and very seldom as here with a ribbon in the buttonhole.
The single loop on his shoulder in combination with the combination of medals hint at the possibility that he was one of the few Austro-Hungarian artillery men sent to fight on the Ottoman front with the Turks and the Germans.
More input for the naming of this officer is more than welcome!
