Marc Lavry born 22 December 1903 in Riga, Latvia, died 24 March 1967, Haifa, Israel.

Israeli composer and conductor. Lavry studied in Riga and Leipzig (Germany) at the Conservatories there, and privately with the conductor Hermann Scherchen and the composer Alexander Glazunov. After working as an opera conductor in Saarbrücken, Germany, he became the musical director and conductor of Rudolf von Laban's Dance Theatre in Berlin. He went on to conduct the Berliner SO (1929–32) and the Riga Opera (1932–4). In 1935, with the ascent of Nazism, he emigrated to Palestine. Between 1941 and 1947 he conducted the Palestine Folk Opera and the Palestine Symphony Orchestra (later The Israel Philharmonic Orchestra), and from 1950 to 1958 he was director of Kol Zion LaGola, the Israeli Radio Broadcast for the Diaspora. In 1962 he settled in Haifa, where he continued his musical activities under the sponsorship of the municipality. Lavry's many compositions – orchestral and chamber music, operas, oratorios, popular songs and music for theatre productions - were influenced by his new surroundings. His style became identified with Israeli music during the 1940's. His symphonic poem Emek (Valley, 1937), based on one of his most popular songs to a poem by Raphael Eliaz, is considered the first symphonic horra. His opera Dan ha'shomer (Dan the guard, 1945), libretto by Max Brod after a play by Sh.Shalom, is the first opera to be composed and produced in Israel.
