Karl Ludwig von Bruck, the mastermind behind the Vienna Coinage Treaty. We chose not to depict Emperor Franz Josef I at this point, who is shown on the coins, but the liberal politician Karl Ludwig von Bruck. Born into the family of a bookbinder in Elberfeld (now Wuppertal, Germany), he worked his way up from a merchant’s position to become Austria’s finance minister. He could almost be described as a beacon of hope for Austrian economic policy. It was tragic – and not just for him personally – that Franz Josef “ungraciously” dismissed him in April 1860 on false suspicions. The then 61-year-old took his own life. This deprived Austria of an imaginative politician who might have prevented its economic marginalization by Prussia.
