Signature

Leonardo Torres Quevedo (Spanish: [leoˈnaɾðo ˈtores keˈβeðo]; 28 December 1852 – 18 December 1936) was a Spanish civil engineer, mathematician and inventor, known for his numerous engineering innovations, including aerial trams, airships, catamarans, and remote control. He was also a pioneer in the field of robotics and computing. Torres was a member of several scientific and cultural institutions and held such important positions as the seat N of the Real Academia Española (1920–1936) and the presidency of the Spanish Royal Academy of Sciences (1928–1934). In 1927 he became a foreign associate of the French Academy of Sciences.[4]

His first groundbreaking invention was a cable car system patented in 1887 for the safe transportation of people, an activity that culminated in 1916 when the Whirlpool Aero Car was opened in Niagara Falls.[5] In the 1890s, Torres focused his efforts on analog computation. He published Sur les machines algébriques (1895) and Machines à calculer (1901), technical studies that gave him recognition in France for his construction of machines to solve real and complex roots of polynomials.[6] He made significant aeronautical contributions at the beginning of the 20th century, becoming the inventor of the non-rigid Astra-Torres airships, a trilobed structure that helped the British and French armies counter Germany's submarine warfare during World War I.[7] These tasks in dirigible engineering led him to be a key figure in the development of radio control systems in 1901–05 with the Telekine, which he laid down modern wireless remote-control operation principles.[8]

From his Laboratory of Automation created in 1907, Torres invented one of his greatest technological achievements, El Ajedrecista (The Chess Player) of 1912,[9] an electromagnetic device capable of playing a limited form of chess that demonstrated the capability of machines to be programmed to follow specified rules (heuristics) and marked the beginnings of research into the development of artificial intelligence.[10] He advanced beyond the work of Charles Babbage in his 1914 paper Essays on Automatics,[11] where he speculated about thinking machines and included the design of a special-purpose electromechanical calculator, introducing concepts still relevant like floating-point arithmetic. British historian Brian Randell called it "a fascinating work which well repays reading even today".[12] Subsequently, Torres demonstrated the feasibility of an electromechanical analytical engine by successfully producing a typewriter-controlled calculating machine in 1920.[13]

He conceived other original designs before his retirement in 1930, some of the most notable were in naval architecture, such as the Buque campamento (Camp-Vessel, 1913), a balloon carrier for transporting airships attached to a mooring mast of his creation,[14] and the Binave (Twin Ship, 1916), a multihull steel vessel driven by two propellers powered by marine engines.[15] In addition to his interests in engineering, Torres also stood out in the field of letters and was a prominent speaker and supporter of Esperanto.[16]
