This artwork is by József Ferenczy (1866-1925), an artist who moved to Timișoara in 1901 when it was part of the Austro-Hungarian empire. This was the golden age of the city, grand new buildings were being constructed and it was very much a cultural hub. Ferenczy also brought up his children in the city and it’s also where he died in 1925.
The gallery names the sitter in the artwork as Stefan Bognia, but I can’t find out anything about him, but I assume he has some military role from his appearance. But it’s the theme of this being very much the golden age of the city that appealed to me, the grandeur that is now faded (but is being restored) was very much in evidence back then.
Whoever the man was, this is how AI thinks he would look today in modern clothing.
