Roland Prinz, who was born as armies began marching across central Europe then spent nearly four decades covering the Cold War and the fall of communism for The Associated Press, has died. Prinz was a linchpin of the AP’s coverage of the turmoil that accompanied the end of the Cold War, starting with the rise of Solidarity in Poland, stretching through the Velvet Revolution in the Czech Republic, the fall of the Berlin Wall and finally the breakup of Yugoslavia. Throughout his career, Prinz was a gentlemanly presence in the news service’s Vienna bureau, helping newcomers navigate life in the Austrian capital and guiding coverage with his broad knowledge of central Europe.
