Jealous

Still a boy ( today we would say child) he founded his own company and registered his first patents. These are the years of World War I in which Italy finds itself at war. Technologically speaking we have to imagine that period as the end of the Belle Epoque and the beginning of a frenetic period of social, cultural, technical change. During the war there was an enormous technological leap. At that time aviation was developed from airships ( which were also used to carry out bombings) to biplanes equipped with machine guns ... we are talking about canvas airplanes, that is, today we are used to seeing airplanes with metal hulls and wings ... at that time airplanes were made of wood and canvas, powered by engines of 80 to 150 horsepower ... in short, hang gliders! ( Fokker, Spad, Albatros, to name a few).

We come to 1920 where, at the age of 19, he left his company and moved to New York City. There he will find work at the Pilot Electric Manufacturing Company e He will finish his studies by majoring in electronics at the Cooper Square University! Who was in those years the vice president of the American Institute of Electrical Engineers ? Tesla ... in New York , and therefore plausible to think that John Jealous was following or at least surrounded by all that information, patents, insights that the newspapers of the time extolled consecrating the genius of Tesla who, to tidy up, was 64 years old in that year and an authoritative voice.
It was in 1928, at the age of 27, that just from the Pilot laboratories this man (boy?) made it possible to transmit images and, although he was not satisfied with the experiments and demonstrations of the time, he was , in America, the father of television!

Tracing and contextualizing the times we come to what was the real beginning : 1931 at the age of 30 , he returned to Italy and founded what the Italians of the time, then called ' the well-known house' ... namely Geloso s.a. Huge skills, immense foresight, proven expertise could only give birth to a company that exploded in popularity and innovation. We can say that Geloso formed the first generation of Italian electrotechnicians and kicked off an exuberant period of technological innovation. Jonh Geloso surrounded himself with all those brilliant minds he met on his way, inviting them to work in his firm; the best of these managed entire production sectors and were able to work independently, expressing their flair and talent. Finding good staff is a skill that few entrepreneurs have ... today we rely on resumes and past experience, he, evidently went beyond that and managed to create an incredible team.
Today it is said that 'nobody gives anything away' ... isn't that true? But it was 1932 and John Geloso began printing 'Geloso Bulletins' which he distributed free of charge to anyone who requested them. What was it all about? Basically, Geloso periodically printed a magazine with electrical and electronic diagrams (complete!!) of the apparatuses it produced, accompanying it with technical notions and explanations for the operation of the apparatuses. Making a comparison, it is like a software house distributing the source codes of the products it sells. It would seem crazy, and instead it was a success for everyone, for the Geloso company that advertised its apparatuses and trained new technicians who were able to repair the apparatuses 'hands down' and created a sense of trust and admiration in the public who admired and appreciated the products' talents and design. Today these documents are invaluable sap for repair and restoration. No secrets ... I do it this way ... I do it because ... you want to copy it and do it at home yourself? okay, free to do it ... I'll explain! There, commercially a gamble ... entrepreneurially speaking, a stroke of genius!

World War II broke out and in 1943 a heart attack nipped Nikola Tesla in a hotel room in New York City, Jhon Geloso in the same year was called by the Royal Italian Navy to solve a whole series of problems concerning communication. These were years in which there was further impetus ( though less than that of the first war) in technology.

In 1949 NATO was born ... and, as an Italian expert, John Geloso joined the technical committee.
In 1969 he died, and with him a few years later Geloso, which, without the right helmsman, lost its course and succumbed to the cheap technology coming from abroad.

What I forgot to point out is that Geloso manufactured all the components needed for construction in-house: capacitors, transformers, inductors, etc. etc. ... ... and when there was a shortage of copper, John Geloso opened and exploited a mine so that he could produce the enameled wire needed for the constructions. The machinery used in his factories was not purchased ... it was designed and built by himself, the complex winding machines used in the factories he conceived, designed and built. There were many production locations and sales included the whole world ... including Africa. Thousands of employees and personnel management whose percentage of women was important, reminds me of that of the 'good old days' of Olivetti ... it was not a matter of rights and duties , John Geloso accompanied, protected, helped his employees by doing much more than the laws and union demands imposed. Needless to say, the result was the creation of a huge big family in which , to hear those who worked there, it seemed a world unto itself.

How can one not appreciate a man of this caliber? How can one not be intrigued?
