Starting Out as an Inventor: Cableways

Torres Quevedo was late to the world of invention, beginning at the age of 35 when he developed the cableway in his hometown of Molledo.

But from then on, he was an unstoppable inventor across a range of fields.

In 1886, while living in Molledo, Cantabria, he built his first cableway. It traversed a 40-meter drop, 400 meters up, and was pulled along by a pair of cows.

In 1887 he patented a funicular with several cables supported by independent counterweights so there was no risk of danger if a cable should break.

Algebraic Machines

Torres Quevedo first gained notoriety in the field after presenting "Sur les machines à calculer" (On Calculating Machines) in Paris.

His importance was then confirmed by his 1900 presentation at the French Academy of Sciences on his paper "Sur les machines algébriques" (On Algebraic Machines).

These texts represented a clear advance on previous knowledge in the field of calculating machines, which were only able to carry out simple calculations such as addition and subtraction.

Between 1910 and 1920 Torres Quevedo demonstrated the advantages of an electromechanical system over mechanical processes.

The inventor's final scientific publication was "Arithmomètre électromécanique" (Electromechanical Arithmometer) presented at the French Academy of Sciences, which will soon reach its 70th anniversary.

Algebraic machines are analog calculators that solve mathematical equations using quantities represented by physical values.

The mathematical process is linked to an operational process involving certain physical values, and the physical result obtained corresponds to the mathematical solution sought.

The system consisted of a calculating machine connected to a typewriter on which the numbers and calculations were typed in the order they were to be performed.

The calculations were then carried out and the typewriter put them down onto paper.

Astra-Torres No 1 Airship in ParisTorres Quevedo Museum


In 1902 Torres Quevedo presented a new balloon design at the Academies of Sciences in Madrid and Paris that caught the state's attention.

In 1904 the government decided to support these experiments and created the Aeronautical Testing Center.

Its main objective was "the technical and experimental study of the problem of aerial navigation and directing the maneuvering of remote engines."

In 1905, with the help of Alfredo Kindelán, Torres Quevedo managed the construction of the first Spanish airship at the Army's Military Aeronautics Service in Guadalajara.

The "España" airship carried out numerous exhibition and test flights with great success.

Spain's limited budget and technological deficiencies led Torres Quevedo to turn to the French company Astra in 1909, granting it the worldwide patent exploitation rights.

However, this did not apply in Spain, where the airship could be freely built by any Spaniard.

Torres Quevedo helped to improve the way the airships flew.

He devoted himself to improving their dynamic stability and detailed his conclusions in an essay that he presented to the French and Spanish Academies of Sciences.

In 1918 Torres Quevedo designed an airship that he named "Hispania," which he intended to make the first transatlantic flight from Spain.

Ultimately, such a flight could not be undertaken due to a lack of funding for the project.

Inventions with Continued Impact: the Telekine and Chess-Player

The key aspects of Leonardo Torres Quevedo's scientific work can be found in 2 essays.

One, titled 'Automation. Its Definition. Theoretical Extent of Its Applications', was published in the Madrid Academy of Sciences journal in January 1914 and again in the "Revue Générale des Sciences Pures et Appliqués" on November 15, 1915.

In 1912 Leonardo Torres Quevedo built a machine that played chess to demonstrate his theories of automation.

He subsequently presented this experimental model in Paris in 1914.

In 1920 he built a second chess-player, introducing significant improvements to which he referred when presenting it.

As an automaton, it offered no real improvement on the first model.

It was more a scientific toy, designed to demonstrate the possibilities of general automation theory.

The Automation Laboratory

Torres Quevedo created an applied mechanics laboratory for the purpose of building advanced machines for businesses and scientists, including some as noteworthy as the winner of the Nobel Prize in Medicine, Santiago Ramón y Cajal.

The Automation Laboratory was founded in the early part of the 20th century, with Torres Quevedo as its director.

It is important to highlight the support the laboratory gave to other scientists (known as the "Generation of 1914"), for whom it produced a range of machines.

The 'Aeronautical Testing Center' was the precursor to what would become the 'Automation Laboratory.'

The name change is evidence of Torres Quevedo's ability to work in different fields. Various members of the scientific community and Spanish universities spent time in the laboratory.
