Maximilian Borsodi's brother

Mr Borsodi was, alongside his brother Maximilian, one of two founders of Borsodi Brothers' Auction House, during his lifetime placed on the Novigrad's main square.

Early life
"Haha, ahem. Name's a historical legacy, Geralt. Auction house was founded by two brothers, Horst's father and an uncle. In this generation--"

- Vimme Vivaldi, to Geralt

He was born in Redania and had at least one other brother, Maximilian, who was close to him. At the beginning of their career, brothers traded with sheep and horses being able to afford only a shed in the city's outskirts. In forty-two years, however, they managed to rise in wealth so much that their auction house became largest and most reputable in the Northern Realms, located on the main square in an impressive three-story building. They also employed Abner de Navarette.

Later life and death
He lived the rest of his life as a rich and respected man, whose name meant something. Unlike his brother, he never married and thus had no children who could inherit his share. That meant Maximilian's two sons, Horst and Ewald, were the only inheritors of the family fortune.
