Oton Vinski (born Otto Weiss; Osijek, 20 March 1877 – 1942, Jasenovac concentration camp) was an influential Croatian banker who was killed during the Holocaust.
Vinski was born in Osijek on 20 March 1877, as Otto Weiss, to a Jewish family of Franjo and Berta Weiss.
He was employed as a procurator and chief executive of the "Croatian Discount Bank" in Zagreb.
During World War II, Vinski was arrested and deported to Jasenovac concentration camp together with his mother in law Ilka Alexander, where they were both killed in 1942.
When his wife returned home, nobody was left.
By mere chance Vinski's wife and sons have survived the Holocaust.
