TORRE Y QUEVEDO Leonardo (1852 - 1936) TORRE Y QUEVEDO Leonardo (1852 - 1936) SCIENCE - TORRE Y QUEVEDO Leonardo (1852 - 1936) - Autograph letter signed Autograph letter signed, dated “Madrid- 9-III-902” by the Spanish civil engineer, mathematician and inventor, considered today as a forerunner to the modern digital computer. His first major task was the patent of a new cable car system in 1887 for the safe public transportation of people, an area of ​​activity that culminated in 1916 with the Whirlpool Aero Car located in Niagara Falls. In the early 1890s Torres focused his research on the field of analog computing. He published Machines algébriques (1895) and Machines à calculer (1900), technical studies that gave him a reputation in France, carrying out the construction of several machines for solving real and complex roots of polynomials. He has been a key figure in the development of radio control systems between 1901 and 1905 with the Telekine, which he created modern wireless remote-control operation principles. An intimate letter addressed to his “Querido Fausto”: “…yo pienso que tiendrá razon su chico y que eso de la veser y lo achaques lo ponderas mas de lo justo por que cuando escribiste estabas la vena exagerar (…) Yo estoy bueno, aunque me sobran canas en la barba y me falta pelo en la parte superior del craneo. Con mis hijos y varias chisladuras, se me va pasando la vida mi sentir y demasiado deprisa para mi gusto, pero en verdad no tengo motivos para quejarme mas que la mayoría de las gentes…”. 3 pp. ½. In-8. Rare. - This item is under temporary import. If the item is delivered within the United Kingdom, it will be subject to a 5% Value Added Tax (VAT) on the hammer price.
