CALLAS AND TEBALDI: (From a commentary by Eleni Vlachou): «I read yesterday that Renata Tebaldi could be coming to sing in Greece this summer. The organizers of the Athens Festival are in negotiations with the Italian soprano, who is currently much in the news. Much of her glory is naturally due to her wonderful voice, but the publicity surrounding her at the moment is partly due to her feud with Maria Meneghini-Callas. THEODOR KOERNER: Vienna, 4 – This afternoon Austrian President Theodor Koerner died of heart failure at the age of 84… The late president was born on April 24, 1873 in Hungary. He later entered the military, reaching the rank of captain at the age of 26. During the First World War he was a professor at the Vienna Military Academy and distinguished himself as chief of staff for Archduke Eugen. After the war ended in 1918, Koerner decided to join the Socialist movement… After the Anschluss in 1938, he refused to cooperate with the Germans and was imprisoned. After the war he was elected mayor of Vienna, and then president in 1951.
