May 5th: On National Communications Day, a fair tribute to a pioneer of Radiotelegraphy

The date of May 5th appears in the Annual Calendar as the “National Communication Day”, celebrated throughout the country. There is also a special celebration abroad as it is an international day of communication. And what is the meaning? “It is the act of transmitting and receiving messages through a type of language: spoken, musical, gestural or other definitions”. Human beings communicate mainly through spoken language. Subsequently increased by an efficient performance provided by technology, through sound equipment adjusted to the image transmitted by the media. The Telegraph is a device used by our ancestors to transmit messages over great distances. Samuel Morse – who created the Morse Code – figures as the person who sent telegraph signals at a distance of 518 meters. Wirelessly, emitting dot and dash signals by means of a manipulator meaning the letters of the Alphabet. In Presidente Prudente, telegraph communications had two points of reference: the Post Office and the Estrada de Ferro Sorocabana. But it was at the Railway Station that the largest Operations Center was practically established, pioneered by a young man of just 15 years of age, who qualified and made a brilliant career as a radiographer: Dary Bonomi Avanzi.


Currently Director of the Avanzi Consultoria em Telecomunicações Group, Dary tells us his biography from the moment he was in the communications area as a Telegraphist, preceded by an initiation course between 1956 and 1957 that brought together 100 candidates with availability of only 30 vacancies. The greatest support he received came from an uncle who practiced this profession and encouraged him to embrace the career of Telegraphist, giving him all the assistance he needed. Already approved, in July 1958 the appointment of Dary for the profession of Telegraphist in Presidente Prudente came out. The boarding took place at Botucatu Station and from there, it ended up in Assis in order to carry out medical examinations. Then he left to pursue his new professional activity in the Presidente Prudente Subdivision. He was 15 years old and was considered “the newest Telegraph operator on the entire railway”.


Our new Telegraphist traces a summary of his professional and pioneering career in the Presidente Prudente region: “in addition to the railroad, he also picked up Morse signals directly from the News Agencies: France Press, Asa Press, United Press and the Soviet Agency Tass”. The captured news was passed on to Radio Broadcasters’ Spoken Newspapers. At the age of 22 he moved to the State Capital, where he met and used new equipment (six in total), including radiotelegraphy used by new companies that he started to provide services: aviation, cellulose, oilseeds and even the Government Palace. From 1983 to the Year 2000 – Advising in the areas of telecommunications and public security. Hence, special advice in the area of ​​telecommunications to newspapers and radio stations and follow-up to various international conflicts such as: Taking power from Cuba, Cold Wars (USA and USSR), Vietnam War, Murder of J.F. Kennedy and others.


In 1980, Dary Bonomi Avanzi was invited to act as Radiotelegrafista of Pope João de Deus in São Paulo and Aparecida. At the invitation of ANATEL, he gave numerous lectures and last year, as a guest of the former Telegraph operator of the Portuguese Navy, he was in Lisbon where he participated in ceremonies, as a representative of Brazil. In addition to performing with the greatest dignity the functions of a Radiotelegrafista, he also has a hobby since 1974 and is part of an Association that brings together Amateur Radio – Class A – with more than 140 member countries. It also includes Presidente Prudente-SP, as one of the largest and most important Brazilian cities.
