Electrical, Mechanical and Lighting Installations of the Municipality of Buenos Aires City, a public role which he would hold until his death. In 1904 he became Professor of Electrical Engineering at the National Industrial School (later the Otto Krause Technical School), which was founded and directed by the engineer Otto Krause in 1893. In the same year he travelled to the United States once more to attend the International Electricity Congress which took place in the city of Saint Louis, where he was vice president of the section on "Power and Light Transmission" and at which he presented an eighty-page work entitled "General considerations on the transfer of lighting services to municipal ownership", which would be included in the Annals of the Argentine Scientific Society. Ruler of the skies: balloons and aeroplanes Aerostatics and balloons Jorge Newbery began wanting to rule the skies when he met the Brazilian aviator Alberto Santos-Dumont (1873–1932). On 25 December 1907, Jorge Newbery and Aarón Anchorena crossed the Río de la Plata in the balloon El Pampero before landing in Conchillas, Uruguay. Although there had been a few previous balloon flights in Argentina, the crossing of the Río de la Plata became a popular event. El Pampero set out from the Sociedad Sportiva Argentina, located in Palermo, on the same land where Campo Argentino de Polo is located nowadays. A few days later, on 13 January 1908, the Aero Club Argentino was created, with Aarón Anchorena as president and Jorge Newbery as second vicepresident. The ACA was located on the Villa Los Ombués estate of local business tycoon Ernesto Tornquist, in Barrancas de Belgrano, Buenos Aires (since torn down and now the location of the Embassy of the Federal Republic of Germany). On 17 October his brother Eduardo (also an ACA member), together with Seargent Romero, went missing in El Pampero and their bodies were never found. These were the first two casualties in the history of flight in Argentina. Despite the tragedy and public opinion starting to consider balloon-flight to be excessively dangerous, Newbery prepared a new balloon, El Patriota, and revitalised aerostatics with the help of socialist representative Alfredo Palacios. One month after the death of his brother, on 24 November, Jorge married Sara Escalante. On 9 April 1909, Newbery wrote the first newspaper article on aviation in Argentina. Entitled "Aeronáutica", the article was featured in the Buenos Aires El Nacional. By that
