“I wonder, he wondered, if any human has ever felt this way before about an android.”*…

Well, yes… Centuries before audio deepfakes and text-to-speech software, inventors in the eighteenth century constructed androids with swelling lungs, flexible lips, and moving tongues to simulate human speech. Jessica Riskin explores the history of such talking heads, from their origins in musical automata to inventors’ quixotic attempts to make machines pronounce words, converse, and declare their love…

The word “android”, derived from Greek roots meaning “manlike”, was the coinage of Gabriel Naudé, French physician and librarian, personal doctor to Louis XIII, and later architect of the forty-thousand-volume library of Cardinal Jules Mazarin. Naudé was a rationalist and an enemy of superstition. In 1625 he published a defense of Scholastic philosophers to whom tradition had ascribed works of magic. He included the thirteenth-century Dominican friar, theologian, and philosopher Albertus Magnus (Albert the Great), who, according to legend, had built an artificial man made of bronze.

This story seems to have originated long after Albert’s death with Alfonso de Madrigal (also known as El Tostado), a voluminous commentator of the fifteenth century, who adapted and embellished the tales of moving statues and talking brazen heads in medieval lore. El Tostado said that Albert had worked for thirty years to compose a whole man out of metal. The automaton supplied Albert with the answers to all of his most vexing questions and problems and even, in some versions of the tale, obligingly dictated a large part of Albert’s voluminous writings. The machine had met its fate, according to El Tostado, when Albert’s student, Thomas Aquinas, smashed it to bits in frustration, having grown tired of “its great babbling and chattering”.

Naudé did not believe in Albert’s talkative statue. He rejected it and other tales of talking automaton heads as “false, absurd and erroneous”. The reason Naudé cited was the statues’ lack of equipment: being altogether without “muscles, lungs, epiglottis, and all that is necessary for a perfect articulation of the voice”, they simply did not have the necessary “parts and instruments” to speak reasonably. Naudé concluded, in light of all the reports, that Albert the Great probably had built an automaton, but never one that could give him intelligible and articulate responses to questions. Instead, Albert’s machine must have been similar to the Egyptian statue of Memnon, much discussed by ancient authors, which murmured agreeably when the sun shone upon it: the heat caused the air inside the statue to “rarefy” so that it was forced out through little pipes, making a murmuring sound.

Despite disbelieving in Albert the Great’s talking head, Naudé gave it a powerful new name, referring to it as the “android”. Thus deftly, he smuggled a new term into the language, for according to the 1695 dictionary by the French philosopher and writer Pierre Bayle, “android” had been “an absolutely unknown word, & purely an invention of Naudé, who used it boldly as though it were established.” It was a propitious moment for neologisms: Naudé’s term quickly infiltrated the emerging genre of dictionaries and encyclopedias. Bayle repeated it in the article on “Albert le Grand” in his dictionary. Thence, “android” secured its immortality as the headword of an article — citing Naudé and Bayle — in the first volume of the supplement to the English encyclopedist Ephraim Chambers’ Cyclopaedia. In denying the existence of Albert’s android, Naudé had given life to the android as a category of machine.

But the first actual android of the new, experimental-philosphical variety for which the historical record contains rich information — “android” in Naudé’s root sense, a working human-shaped assemblage of “necessary parts” and instruments — went on display on February 3, 1738…

[There follows a fascinating account of examples from the 18th and 19th centuries…]

… In the early part of the twentieth century, designers of artificial speech moved on from mechanical to electrical speech synthesis. The simulation of the organs and process of speaking — of the trembling glottis, the malleable vocal tract, the supple tongue and mouth — was specific to the last decades of the eighteenth century, when philosophers and mechanicians and paying audiences were briefly preoccupied with the idea that articulate language was a bodily function: that Descartes’ divide between mind and body might be bridged in the organs of speech…

As we muse on the mechanical, we might spare a thought for a man whose work helped pave the way for androids as we currently conceive them: J. Presper Eckert; he died on this day in 1995. An electrical engineer, he co-designed (with John Mauchly) the first general purpose computer, the ENIAC (see here and here) for the U.S. Army’s Ballistic Research Laboratory. He and Mauchy went on to found the Eckert–Mauchly Computer Corporation, at which they designed and built the first commercial computer in the U.S., the UNIVAC.

As we watch what goes around come around, we might send very carefully-crafted birthday greetings to Jacques de Vaucanson; he was born on this date in 1709.  A mechanical genius, de Vaucanson invented a number of machine tools still in use (e.g., the slide rest lathe) and created the first automated loom (the inspiration for Jacquard).  But he is better remembered as the creator of extraordinary automata.  Among his most famous creations:  The Flute Player (with hands gloved in skin) and The Tambourine Player, life-sized mechanical figures that played their instruments impressively.  But his masterpiece was The Digesting Duck; remarkably complex (it had 400 moving parts in each wing alone), it could flap its wings, drink water, eat grain– and defecate.

“Historians will silently murder you with their eyeballs if you say ‘Dark Ages’ unironically”*…

Henrik Lagerlund explains how medieval thinkers foreshadowed modern physics in investigating the character of machines, devices, and the forces that animate them…

The Middle Ages still suffers from the embarrassment of comparison. Before it glowed the light of the ancient Greeks – the great, early speculators of the natural world and our place in it. After the Middle Ages came the scientific revolution – Copernicus, Galileo, Newton – and the surging onrush of modernity. Even if the idea of the so-called ‘dark ages’ is waning, there remains the widespread impression that the Middle Ages is in some sense a time of stagnancy, especially in its understanding of science and the natural world. Is this an accurate view of medieval science? There is one discipline, often overlooked, that serves to illuminate the Middle Ages, as well as its place in the history of scientific thought: mechanics.

The predominant assumption about the rise of modern science is that it went hand in hand with the conception of nature as a universal mechanism. By viewing nature in this way, it could be studied, analysed and experimented upon with mathematical rigour, and its functioning could be elucidated by physicists harnessing empirical methods. While the motion of inanimate bodies became theorised on the model of projectiles, some mechanical philosophers even claimed that the complex organisation of animate bodies could be understood on the model of levers, springs, pulleys and other mechanical devices. This step – nature as a universal mechanism – is often seen as the important break from the Middle Ages.

But, in fact, mechanics was not unknown in the Middle Ages, and medieval thinkers continuously discussed mechanical problems at the crossroads of natural philosophy and mathematics. Mechanics enjoyed continuous interest and progress throughout the Middle Ages, and modern physicists and mathematicians relied to a large extent on results inherited from the Middle Ages. But mechanics as a scientific discipline did not always go under that name.

Taking this into account, a close look at the Middle Ages reveals that the consideration of mechanics as a core part of physics, together with the mathematical treatment of weights, forces and resistances, all generally assumed to characterise the birth of modern science, was there long before Galileo. That means that medieval thinkers did not simply lay the foundations of the scientific revolution. It means they started it. There should be no more embarrassment of comparison for that great era of scientific thought, especially when we review the fascinating history of mechanics…

As we give credit where credit is due, we might note that today is the Summer Solstice– or Midsummer– the day with the longest period of daylight and shortest night of the year, when the Sun is at its highest position in the sky.

Often celebrated during the Middle Ages as the Feast of St. John (six months “opposite” the celebration of Christ, for whom John “paved the way”), it has pagan roots, and was often observed with songs, games, displays, processions, mystery plays, and dancing (often around a Maypole), which served to repel witches and evil spirits.
