150th Anniversary of the Birth of Father Landell de Moura The Brazilian Father of the Radio The Brazilian Post is issuing a postage stamp to commemorate the 150th anniversary of the birth of Father Landell de Moura, the pioneer of radio broadcasting in Brazil. Roberto Landell de Moura was a telecommunications pioneer. He was the first person to broadcast the human voice over a distance without using wires. This was the forerunner of what was then called radiotelephony, which is nothing more than what we nowadays know as radio. He was born on January 21, 1861, in Porto Alegre, and was ordained as a priest in Rome in 1886. Besides theology, he also studied physics and chemistry at the Gregorian University, in Rome, Italy, where he started to develop the theory that formed the basis for his different inventions. Landell, who was both a priest and a scientist, carried out his first experiments at the end of the 19th century. At the same time, whilst Landell’s equipment was broadcasting voices, Guglielmo Marconi, the famous Italian inventor who invented wireless telegraphy or radiotelegraphy, was only transmitting signals in Morse code (groups of dots and dashes). The Canadian physicist Reginald Fessenden was also one of the pioneers of voice transmission (1900), but his experiments were carried out after the Landell’s. Landell was self-taught in the emerging science of radio-electricity and did everything alone. He had little in the way of financial resources yet he designed apparatus, made parts, and insistently tested his equipment until he successfully managed to achieve wireless transmission. In spite of the countless difficulties, he patented his inventions in Brazil (1901) and in the United States (1904). In his patent letter, Father Landell recommended using short waves to increase the broadcast distance, a fact that would later be recognized by other scientists. He also used light to transmit messages, which is the same principle as is used in modern fiber optics. Besides the radio, he designed the television in 1904 (though it was only officially invented in 1926), he was the pioneer of the teletype and one of the first pioneers of remote control using radio waves, all off his own back. Father Landell died anonymously in his home town on 30 June 1928. The story of Roberto Landell de Moura, a man ahead of his time, is still not known by many of his countrymen. Father Landell’s life story has been told in several books published bin Brazil and one in Germany. All his materials and equipment have been collected together at the History and Geography Institute of Rio Grande do Sul (IHGRGS). The History and Geography Institute of Rio Grande do Sul Porto Alegre/RS The League of Brazilian Amateur Radio Transmitters (LABRE) would also like to take this opportunity to commemorate the 150th anniversary of the birth of Father Landell de Moura, the pioneer of wireless human voice transmission, and the Patron of Brazilian Amateur Radio Transmitters. His importance to Amateur Radio Transmitters and to Amateur Radio Transmission in Brazil became apparent when the Committee of the State of São Paulo League of Amateur Radio Transmitters (LABRE–SP) prepared a study to propose that the Priest and Scientist Landell de Moura be declared the Patron of Brazilian Amateur Radio Transmitters. A meeting was held in Brasília–DF, on September 25, 1981, where Roberto Landell de Moura was elected the Patron of Brazilian Amateur Radio Transmitters by the Federal High Council of LABRE. LABRE, the only organization to represent Brazilian Amateur Radio Transmitters at the national level, recognizes that were it not for this famous Brazilian, telecommunications would not have been right at the beginning of the 20th century and the first radio broadcasts would not have been made in 1905. At this time, as the 150th anniversary of his birth is being celebrated, we Amateur Radio Transmitters could not be absent, especially since Brazilian Amateur Radio Transmitters are guided by the motto: “He who does not live to serve, has no reason to live,” which was, at the core, the motto that he lived by. His great achievements have already been acknowledged with the setting up and naming of institutions and organizations such as the “Father Landell de Moura Educational Foundation,” in Porto Alegre/RS; the “Roberto Landell de Moura Research and Development Center,” founded in 1976 by Telebrás; and by the Brazilian Army which, in 2005, named the First Telematics Center, in Porto Alegre/RS, “The Landell de Moura Telematics Center”. LABRE shares the same ideals as all Brazilians that are involved with extolling the Patron of Brazilian Amateur Radio Transmitters and showing the world his achievements and, without a doubt, this stamp that refers to the 150th anniversary of his birth is yet another important tool for drawing attention to this very important figure.
