John von Neumann (right).
The Neumann family fled Hungary in 1919 to escape the short-lived communist regime led by BĂ©la Kun.1
Following the collapse of the previous government in March 1919, Kunâs administration established a Soviet republic that relied on the "Red Terror," a policy that antagonized much of the population. To avoid the instability and political upheaval of this period, the family left for a brief period of exile in Vienna and the Adriatic resort of Abbazia (now Opatija, Croatia).21
