In his book “Conventia de la Montreux, 1936” (Romania, 1967), on the subject of regulating the passage through the Bosphorus and Dardanelles Straits, Robert Deutsch was the first to prove that the viability of a convention or treaty is related to the weight of regulations that derive from compromises that are based on the prognosis of the future of the contracting parties.
In his work,“The Food Revolution in Eastern Europe and the Soviet Union” (Westview Press, 1987) - nominated for a Pulitzer Prize - he managed to prove, for the first time in scientific literature, that the collapse of the socialist system will occur due to the discontent of educated population whose increasing consumer needs cannot be satisfied by communist regimes.
Between 1970 and 1980, Robert Deutsch has published a series of historiography works. The more notable are the one on psychohistory (published in Switzerland) and the one about the French school Annales (published in Germany), from the perspective of intellectual competition between Paris and the French countryside. In his essay “Cross-cultural History of International Relations” (Stanford,1986), driven by intellectual inquisitiveness, Robert Deutsch has attempted to quantify curiosity using a database of the WIPO (World Intellectual Property Organisation) with millions of translations done by 47 countries over a period of over 100 years, categorized using the universal decimal classification of libraries. The conclusion of this essay is that the role of curiosity and imitation in the advent of civilisation follows the model of the ebb and flow of tides, differing from the previous models proposed by Vasile Conta or Oswald Spengler.
Since the year 2000, Robert Deutsch has retired from academic activity while still providing financial support to Stanford, Hoover Institution and the Deutsch Foundation in the US.
He is the founder and Honorary President of the Romanian Golf Federation and the former owner of the Lac de Verde Golf Club from Breaza, Romania.
