Imagine it‘s the early 20th century and you need to solve complex mathematical equations with many variables. For anything beyond basic arithmetic, such difficult and tedious numerical calculations required teams of human "computers," typically women mathematicians who manually computed equations. Even skilled professionals might spend months solving a single complex formula!
Leonardo Torres changed all this in 1920 when he unveiled an electromechanical calculating machine that automated the process of finding roots of polynomial equations up to degree eight. Let‘s explore Torres‘s life, this groundbreaking invention of his, and how it paved the way for modern computing technology.
Who Was Leonardo Torres?
Born in 1852, Leonardo Torres y Quevedo was a prolific Spanish mathematician and engineer whose innovative work in automation and computing earned him a place in the history books.
Educated as a civil engineer, Torres also had an exceptional talent for mathematics. During extensive travels around Europe, he learned of the latest developments in areas like mathematics, physics, and the brand-new field of electricity. The work of brilliant inventors like Thomas Edison and Charles Babbage clearly inspired the young Spaniard.
Settling back in Spain in the 1880s, Torres first gained renown for engineering accomplishments like designing a cable car system over Niagara Falls. But he soon began working on more abstract problems in mathematics and computation as well.
He recognized the massive potential of machines that could not just calculate, but actually apply computational methods to higher math in new ways that augmented human capabilities.
The Game-Changing Calculating Machine
Torres completed designs for his calculating machine by 1910, spending the next crucial decade constructing improved prototypes.
By 1920, he unveiled what would be his final design to audiences in Paris. For a world still using fairly basic mechanical calculators, the stunning capabilities of this machine represented a gigantic leap forward.

| Power | Electric motors |
| Computation | Determine roots of polynomial equations up to degree eight |
| Method | Analog computation using "unending spindles" |
| Purpose | showcase, not commercial product |
Table: Key highlights of Torres‘s calculating machine
Let‘s break down what made this calculating machine so revolutionary. Previous devices could only handle basic arithmetic. But Torres‘ machine could determine roots of complex polynomial equations mathematically. This is key because polynomial equations are essential in modeling real-world problems in physics, engineering, and more.
His use of analog computation using ingenious components called "husillos sin fin" (unending spindles) enabled continuous, automated calculation. The algebraic foundations he developed marked groundbreaking mathematical theory for the era.
According to historians, this device was primarily a demonstration piece to showcase Torres’ knowledge rather than pursue commercial success or patents. But it nonetheless represented enormous leaps forward in mechanical calculation. Most importantly, it served as a precursor to the first true digital computers that would emerge decades later.
Torres the Polymath: Chess, Remote Control, and Beyond
Torres was a prolific "polymath" inventor whose innovations spanned many technological fields. For example, his early work developing wireless remote control vehicles and telegraphy technology actually predated broader adoption of radio communications by a wide margin.
He also constructed multiple versions of chess-playing automatons, implementing automated motors and sensors to allow these machines to play full games against human opponents independently. This was arguably the world‘s first "computer game!"
These many inventions demonstrated Torres’ exceptional talent blending engineering, computation, mathematics, and creativity. Not all these technologies persisted, but they made Torres an influential figure in the scientific community and earned him fellowships and prestige in several European engineering societies.
Legacy: An Overlooked Pioneer
While less well-remembered than computing pioneers like Babbage, Turing, and Von Neumann, Leonardo Torres y Quevedo clearly deserves more recognition for his pioneering early work fusing computation, automation, mathematics and engineering.
His calculating machine of 1920 solved key problems in analog computation and presaged advanced capabilities before electronic digital computers even existed. The underlying concepts – replacing manual human mathematical effort with automated, engineered processes – contained the seeds of modern computing.
Torres died in 1936 at the pinnacle of his fame, working on new innovations literally to his final days. One can only speculate on what additional advances he may have made if he lived into the computer age.
But between the calculating machine and his many other thinking machines, Torres stands clearly as one of the most innovative precursors to modern computing. Any history of computer science would be incomplete without honoring this prolific Spanish inventor and his revolutionary early computing achievements.
