Hi Paul,
That’s not a lot to work with. I can tell by the surname that he was Jewish.
On Ancestry, there is a guy called Peter Lax who has created a large collection of Silesian Jews.
It also includes Fedor Badrian, who was married to Lene/Helene Nebel.

According to the information provided, Fedor was born on 10 Aug 1835 in Pleß (now Pszczyna) and died 7 Jun 1877 at a monastery hospital in Neustadt O/S (Prudnik).
You would have to request the death record from the state archive in Opole or ask Peter for it. I also cannot find the source for his birth. All records I can find for Pleß start the decade after.
Kind regards,
Michael
