Ștefan Octavian Iosif (Romanian pronunciation:[ʃteˈfanoktaviˈanˈjosif]; 11 October 1875 – 22 June 1913) was an Austro-Hungarian-born Romanian poet and translator.
His friendship with Anghel came to an abrupt end after the two writers fell in love with the same woman, Natalia Negru. She was first married to Iosif, but divorced him in order to remarry Anghel. The latter was drawn to despair by her infidelities, and committed suicide in 1914. Iosif had died the year before, at a hospital in Bucharest, after having suffered a stroke. He was buried at Bellu cemetery.
