due to the absence of the electromagnetic interference that exists today. The device severely distorted the voice, making it often incomprehensible, but its effectiveness in transmitting sound was proven. The device was publicly demonstrated in 1984, and Almeida describes the event: "The device was presented in public, for the first time, at the closing ceremonies of Semana da Pátria. On September 7, 1984, in front of the Monument to the Expeditionary, in the capital of Rio Grande do Sul, the governor of Rio Grande do Sul, Jair Soares, uttered, through the handset, two words that were clearly heard by hundreds of people: 'Porto Alegre'. unquestionably the functionality of Father Landell's invention ". In 2004 Marco Aurélio Cardoso Moura, with technical support from Rolf Stephan and Alexandre Stephan, from Industrial Eletro Mecânica Apex Ltda., Made another reconstruction, also functional and also with a very distorted sound, receiving better in the range of medium waves and in FM. For Ferrareto, "the existing evidence points, therefore, to the success of Landell de Moura in the transmission and reception of voice even though the quality did not allow the immediate practical application of the devices created by the Brazilian. The improvement of these in the national territory would depend on a significant contribution of resources based on an awareness of the strategic importance of such technology. Consciousness that did not exist in Brazil then ". The qualification and stabilization of the signal would depend on technological advances that would be made a little later, mainly through John Ambrose Fleming, Reginald Fessenden, Edwin Howard Armstrong and Lee De Forest. Later life Landell returned to Brazil after receiving the U.S. patents. An article in the March 11, 1905 Jornal do Commercio stated that his inventions "can reach easily from 30 to 50 kilometers and even at greater distances". In December 1905 he submitted a request to the São Paulo state legislature for funding to support experimentation, however, this was not approved. After this he apparently ended research into long-distance communication. Later reports stated that he was working on ideas for a "Telephotorama", or "The Distance Vision". He also did photography research and reported effects similar to Kirlian photography. On January 21, 2011, Brazil issued a stamp commemorating the 150th anniversary of Landell's birth, which shows him using a device described in one of his 1904 United States patents.
