international affairs and was regularly consulted on the history of Australian diplomacy and foreign affairs. Honours In 1960 Harry was appointed an Officer of the Order of the British Empire (OBE). In 1963 he was appointed as a Commander of the Order (CBE). In 1980 he was appointed a Companion of the Order of Australia (AC), "for public service, particularly as a diplomatic representative". Esperanto Throughout his life Harry maintained an interest in the constructed international language Esperanto, which he began to learn as a student in 1937. He was an active evangelist for the Esperanto cause, and a prolific Esperanto writer, conference-goer, lexicographer, translator, administrator and a committed promoter of the potential of an international language to bring down the barriers of suspicion and intolerance that exist between nations. His most notable contribution to Esperanto and its cause was when he was serving as the Australian Ambassador to the United Nations in 1977. NASA, the US space agency, had programmed the launch in that year of two space probes, Voyagers 1 and 2, which were designed to take and send back to earth images of the outer planets, then continue beyond the solar system after escaping the sun's gravitational pull to become the first man-made objects to leave it. NASA and the cosmologist Carl Sagan decided to create identical golden records to attach to each probe that were designed to tell the story of the Solar System, and mankind, should one of them ever come into contact with extraterritorial intelligent life. Engraved on each record was, among other things, a soundtrack containing a compilation of 54 peace greetings to the universe recorded in different languages by various UN delegates. Harry succeeded in persuading the UN and NASA to accept a message in Esperanto. It is located third-last on track 3 of the golden records and says: “We strive to live in peace with the peoples of the whole world, of the whole Cosmos.” Translation Before the 1972 Olympic Games in Munich, Germany, when he was serving as Australia's ambassador to West Germany, Harry translated into Esperanto several important UN documents, including the Charter and Universal Declaration of Human Rights. He edited a modest booklet with sport related terms in Esperanto and their translation into English, French and German. For decades he collected specific Australian expressions and published the first Australian English-Esperanto dictionary.Harry also wrote an English-Esperanto bridge (card game)
