A Tribute to Dean Rosenzweig

Dean Rosenzweig passed away in the second week of January 2007. I met Dean for the first time 24 years ago, during the winter School Foundation of Computation Theory Profs. Rasiowa, Karpinski and Kirin had organized at the Inter-University Centre for Post-graduate studies in Dubrovnik from 16.1. 29.1.1983. Dean attended my lectures on Complexity of Logical Theories and I noticed him as a particularly bright, sharp and very knowledgeable young colleague with a strong taste for elegance in mathematical matters and a wide range of interests. I vividly remember strolling with Dean and his friends long night hours through the streets of the historic Dubrovnik and along the town wall, discussing issues of logic, complexity, semantics whilst enjoying the splendid view on the town, its harbor, the hills and the sea. We shared the love for Dubrovnik and the town became our fate.
