History may seem to be just a sequence of events from the past. But for me, it is also a matter of imagination: we do not know everything, not everything is recorded in history books, we still have much to discover or, first, imagine. Rare autographed documents have always stimulated my imagination and this piece is no exception:

- "Good evening Sir, my name is Alberto Santos Dumont."

- "It is a real pleasure and honor to meet you Mister Dumont, I heard a lot about you, I am Emil Berliner ."

In 1913, perhaps Santos Dumont (1873 - 1932) and Emil Berliner They met during a dinner in Washington and talked for many hours about aviation and engines... Suddenly, a fan approached shyly, and asked for his idols' autograph on this technical pamphlet.

But who was Emil? Berliner ? American of German origin, Berliner (1851 - 1929) was an engineer-inventor with a passion for technology. He excelled in two main fields: sound and aircraft motorization. It all began in 1878 when he managed to significantly improve, with a transmitter-receiver, the telephone recently invented by the American Graham Bell. Ten years later, he became interested in the work of another genius of his time, Thomas Edison. He then developed the gramophone and improved techniques that revolutionized the growing music industry... Soon records were in every home!

But it wasn't music that brought Santos Dumont and Berliner , and yes aeronautics, also born at the beginning of the 20th century. In 1908, Berliner invented a lighter and more powerful engine for airplanes and created the Gyro Motor Company in the United States for larger-scale production. Santos Dumont was certainly interested in this equally audacious inventor, who, ten years later, in 1919, with the help of his son Henry, also designed one of the first helicopters capable of transporting a man.

Gyro Motor closed during World War I, but aviation progress, thanks to pioneers such as Santos Dumont and Emil Berliner , never stopped. This document is a unique association of two great inventors, a valuable piece for collectors specializing in aviation or music.
