Abstract
The routine use of iodine tincture in medicine represents a turning point in the history of surgical procedures. It was the Istrian doctor Antonio Grossich (1849-1926) who first defined and applied the best formula and demonstrated to the world its superiority over other antiseptics. Although his was a life guided by medicine and the steadfast translation of his political ideals into practice, Grossich's achievements were somewhat obscured by his active involvement in the Istrian irredentism of the first decades of the wentieth century.
