The engineer John Geloso was born at Canada de Gomez in Argentina on January 10th 1901, where his parents had temporarily moved from Piemonte, a region in North Italy.
In 1904 the family moved back to Savona in Italy where he studied at the nautical school. With method and constancy, basilar gifts for him, in the studies he tried to put into practice what he was learning. As a matter of fact he instituted a school for candidate engine drivers of the national railways when he was still a student. For this course of studies he published instalments with
mechanical pictures written in clear and simple way often suitable to be understood from old people.
This was another occasion to show a particular and premature liking for mathematical sciences, technical drawing, mechanical and in particular for electro technical.
When he was a teenager who was studying and teaching he worked as cameraman in the father’s firm; he dedicates himself to study music that will fascinate him during his entire life, associating technical ability to a strong artistic sense.
He will always find in music concentration and peace during his activity of planning.
After finishing school he started an electromechanical workshop, that soon became a small firm, producing items he had personally patented.
Despite the hard historical period, due to the economical crisis post war and the lack of collateral industries, this activity was successful thanks to his vocation and his will reaching a great economical stability.
He left this consolidated firm due to his need to look for wider horizons of work and search. The attraction was coming from the most developed country suitable to satisfy his ambitions: the United States.
In 1920 he left Italy bringing with him only his genius. On his own, when he was very young , unknown , without support and using only his experience he succeeded in less than two years in fitting into an activity that was suitable to his skills. He started to work for the Pilot Electric Manufacturing Company in New York as the president Mr. Isidor Goldberg perceived immediately his skills and appreciated him as genial and tireless collaborator. He graduated electronic engineer at the Cooper Square University and in 1925 he married Mrs. Franca who will be his partner for the whole life and will share deeply with him his work. 
Soon he was appointed “chief engineer” by the Pilot president solving promptly all the problems affecting the development of radio at that time (for example receivers AC supply, single command for frequency change, acoustic improvements, ect)
In this way he could fully express in Pilot his personality and realized items and apparatus that gave prestige to the company and to him personally, in USA and all around the world. Remaining in the United Stated he related his name also the an extraordinary event for the time: in 1928 when he was 27 Engineer Geloso realized the first series of experimental televisive transmission in America and in the whole world thanks to apparatus he built and manufactured in Pilot.
It was a system that we could call “pioneer” now, that used in transmission and receipt the Nipkow disc with 44 holes and 15 frames per second. The transmission were between New Jersey and the Philosophy Hall in the university of New York in front of several famous scientists and technicians belonging to the radio history like Lee De Forest, Hugo Gernsback and other famous figures. The result was resounding, both for the technical world and for the public and newspapers gave wide importance to this event. Eng. Geloso was not satisfied with this result from a technical point of view. He thought that this experiment was only a first step of a long series of improvements in a new field that will become important. He went on applying himself with great importance to the problems of radiophony : this was the aim of his entire working life.
