He was born in 1893. He was a revue theater writer and a journalist at Athenian News [Athinaika Nea] and Proia newspapers. As a correspondent of the latter, he personally met Mussolini in Rome. During the Metaxas regime he also served as Director of the University of Athens General Archives and Publications. He fought in the war in the Albanian front. After the formation of the occupation government by Tsolakoglou, he was transferred from the University and became Director of the Press and Radio. On 8.5.1941 he was appointed General Director of the Greek National Theater, an inseparable part of which back then was the newly founded GNO. He served for 2 years. During his directorship all work contracts at the GNO were terminated. He also suggested that conductor Walter Pfeffer and director Renato Mordo leave GNO, on account of their Jewish origin. At the same period he worked regularly for the Italian propaganda. In December 1942, the workers assembly accused him of collaborating with the occupation forces. In April 1943, Giokarinis introduced two new operas in the GNO repertoire: Lucia di Lammermoor and Adriana Lecouvreur with artists brought from la Scala di Milano and the Royal Opera of Rome, in order to “elevate the artistic level or the Greek musical theater”. Before liberation (12.10.1944) Giokarinis fled to Italy, possibly to avoid charges against him. He then moved to Berlin and after the war to Paris, where he died around 1950. The following day from the liberation, the Journalists Union terminated his membership.
