The Battery: How Portable Power Sparked a Technological Revolution by Henry Schlesinger

In describing how the torpedo fish may have worked—essentially reverse engineering the creature—Nicholson sketched a rough blueprint for the first true battery. With papers endorsing and refuting the two differing theories circulating between supporters of both sides, Galvani in some of his last writings proffered the idea of two different types of electricity—animal electricity and common electricity. Not quite a complete concession, the good doctor’s suggestion was closer to a compromise based on diplomacy and perhaps weariness with the debate rather than experiment or scientific fact. Volta, still working hard to prove his bimetallic theory, offered up his own compromise. He would admit that animal electricity exists, but not in the way that Galvani described—accumulating in muscles, particularly in severed limbs and small pieces of muscle. Yes, the nerves may act as conduits for electric fluid, Volta allowed, but that fluid doesn’t originate in the muscles.

In late 1801, he demonstrated the battery for Napoleon himself, who had a keen interest in science, both personally and as a public relations tool. Napoleon’s well-publicized interest in science seemed to have a somewhat calming effect on the ruling class, and in 1810, Napoleon made Volta a count. Volta’s public demonstrations, including an engagement at the Royal Society, focused on the battery’s design and function rather than theory and touched only lightly on the controversy over animal electricity that had lasted eight years. Volta carried with him a small, pocket-sized battery as well, showing how the device could be scaled down for portability—though its diminutive size proved less impressive than the larger pile or crown of cups. Soon, other natural philosophers began giving their own demonstrations of the device. One of the strangest public performances was offered up by Étienne-Gaspard Robertson.

Indeed, the first patent for a battery would come several decades in the future, well into the nineteenth century and long after his death. Patents for electrical devices, of course, were difficult. It was necessary to show a useful application, and the few that did receive patents at the time often listed medical purposes. NOT SURPRISINGLY, WITH A DEVICE capable of producing a continuous flow of electrical current, the debate surrounding animal electricity was soon forgotten. Unlike a Leyden jar, which required constant laborious charging and from which electricity exploded in an electrostatic burst, the battery was easily constructed out of readily available materials and provided a relatively long-lasting and steady flow of current with which to experiment. It’s also interesting to note just how little desire there was to explore the way in which the battery produced its charge.

He pondered a variety of explanations, struggling with the accepted belief that animals generate a special kind of electric charge in their muscles and transmit it through their nerves. This “animal electricity” was believed to be different from static electricity or lightning and unique to each animal. Galvani believed his experiments had elicited animal electricity rather than ordinary, non-vital electricity. Volta doubted Galvani’s claim: If so, why did a living animal’s leg respond only when he linked spine to muscle with a bimetallic conductor? Why not a conductor made of only one metal as well? Volta suspected that the electric charge demonstrated by the frog’s response came not from the frog but from the contact between the two dissimilar metals—a conclusion that offered an exception to the animal electricity theory and thus challenged its validity. To confirm his suspicion, Volta tried another experiment.

He prepared a frog leg with a long piece of nerve extending out of the thigh. To the bare nerve, but not touching the thigh, he then clipped two leads from a weakly charged Leyden jar. The leg muscles contracted. The current from the Leyden jar had stimulated the leg muscles even though it had circuited only through the nerve. To Volta, that meant the current didn’t originate in the muscle, as the animal-electricity theory proposed. Volta then administered his coup de grâce: he prepared another frog leg with a similarly exposed crural nerve, but instead of connecting the nerve to a Leyden jar, he clipped on an arc of two dissimilar metal strips, one of tin leaf and the other of brass. “Instantly the entire limb will be excited into convulsions and kicks,” he wrote, “yet the limb has not been touched, and it is inconceivable that it could be reached by the electrical fluid, which has traveled only between . . . two adjacent parts of the nerve.”9 If he could make the frog leg jump by attaching a bimetallic conductor, Volta concluded, “then there is surely no reason to assume that a natural, organic electricity is at work here.”10 Volta’s “nerve only” experiment: (a) with Leyden jar, (b) with bimetallic conductor.

Volta was generous enough, or sensitive enough to the politics of science, not to try to crush Galvani entirely. He praised him instead with a qualified superlative: “Galvani’s great discovery of a full-fledged animal electricity,” he announced, “remains solid and stable; nonetheless, it must be limited to fewer phenomena, and nearly all his suppositions and explanations collapse.”11 Volta went on to prove that no animal tissue need be part of the apparatus to make electricity. Years intervened between Galvani’s 1792 report and Volta’s ultimate response, years of debate across scientific Europe and of further experiments and reports.

If the Life Force was ‘super-added’, some power outside man must obviously have added it.8 In drawing his analogies between Vitality and electricity, Abernethy also called on the authority of Humphry Davy’s Bakerian Lectures at the Royal Society. Like many scientific men of the day he was entranced by the potentialities of the voltaic battery, and its possible connections with ‘animal magnetism’ and human animation. Electricity in a sense became a metaphor for life itself. ‘The experiments of Sir Humphry Davy seem to me to form an important link in the connexion of our knowledge of dead and living matter. He has solved the great and long hidden mystery of chemical attraction, by showing that it depends upon the electric properties which the atoms of different species of matter possess…Sir Humphry Davy’s experiments also lead us to believe, that it is electricity, extricated and accumulated in ways not clearly understood, which causes those sudden and powerful motions in masses of inert matter, which we occasionally witness with wonder and dismay.’9 The lectures excited great interest in the medical profession, but not yet among the general public.

The art of living happy is, I believe, the art of being agreeably deluded; and faith in all things is superior to Reason, which, after all, is but a dead weight in advanced life, though as the pendulum to the clock in youth.’106 In July he went down to the coast to collect some specimens of the electrical eel or torpedo fish at Trieste. He had renewed his interest in Vitalism and the mysteries of animal electricity. But he hurried back to Laibach, again writing to Jane almost teasingly: ‘I am just returned to my old quarters & my pretty Illyrian nurse, after an excursion of a fortnight to Trieste…I succeeded in my projected experiment on the Torpedo and I have I think been able to establish a new principle with respect to the species of Electricity which will be a [gain] in Nat Science.’107 He worked on throughout the summer, trying to believe he was convalescing, and remained at Laibach as long as possible, until the autumn weather broke and the snowclouds began to gather in the mountains.

He stubbornly sent off another scientific paper to the Royal Society, on the ‘animal battery’ contained in the body of the torpedo or electric eel. It was published on 20 November 1828. He had now submitted forty-six papers to the Society, his first on the voltaic battery long ago in June 1801, and his most famous one on the safety lamp in 1816. He did not want the torpedo to be his last, and he continued to investigate the mystery of ‘animal electricity’ and its possible connection with the universal principle of life. John Herschel would be particularly struck by this paper, which compared the electric eel to a voltaic battery, asked whether the eel could exert this ‘most wonderful power’ at will, and speculated whether the human brain itself might be ‘an electric pile, constantly in action’.144 Nature held other analogies, too. A late autumn 1828 entry in Davy’s private journals reads: ‘Bees, wasps and various winged insects, which appeared to me to be of the Vesper or Apes families were feeding in almost every flower, their tongues searching the honey.

In 1780, Italian Luigi Galvani and his assistant were dissecting frogs, and the assistant dropped a metal scalpel on a frog’s leg (yes, apparently they tasted like chicken back then as well.) The frog twitched and Luigi proudly announced his discovery of “animal electricity.” He then spent 20 years doing to frogs and birds just about anything he could think of including touching their legs and wings with brass and iron and copper and zinc, and hanging them on brass hooks. Another Italian, University of Pavia Professor Alessandro Volta, was a skeptic of animal electricity. Instead, he was more intrigued by the metals. Volta figured the frog was just a detector of electricity, not the source. He visited Galvani and noted that when Galvani used a steel knife and a tin plate, the frog moved. So Volta put a frog between a stack of brass and iron and sure enough it twitched.

Scribonius Largus, the court physician for the Roman emperor Claudius more than two thousand years ago, recommended the application of a live torpedo fish—an electric ray capable of delivering up to 200 volts at a time—to the forehead for relief of headaches, and other cultures around the world prescribed electric fish for everything from epilepsy to exorcism.2 By the end of the eighteenth century, the great debate between Luigi Galvani and Alessandro Volta had introduced the idea of “animal electricity” to the world. Galvani’s nephew Giovanni Aldini soon began using “galvanism” to treat depression in Bologna (as well as applying electricity to the brains of freshly decapitated criminals to elicit bizarre facial expressions).3 In the two centuries since then, various forms of electrical brain stimulation for mental health and other conditions have drifted in and out of fashion with decidedly mixed results.

The ideas about galvanism Mary cites were also wrong, though still widely held at the time. They refer to the work of Italian scholar Luigi Galvani, who hung some severed frog’s legs from a brass hook and observed that on touching them with an iron scalpel they twitched. He mistakenly took this movement as a sign of some intrinsic life essence retained in the dead matter, which he called ‘animal electricity’. Of course the electricity was not in the frog’s leg but was actually due to the simple battery effect that the brass hook created when his iron scalpel touched the dead, wet appendage.4,5 These scientific theories and mistakes don’t really matter though, because like all good sci-fi the science was never the point in the story Mary created. Mary Shelley’s famous tale is, of course, Frankenstein: or, The Modern Prometheus, a tale about an obsessive, ambitious scientist who relentlessly pursues his scientific experiments achieving extraordinary results.

In 1838, another Italian, Carlo Matteucci, a professor of physics at the University of Pisa, showed that “an electrical current accompanies each heart beat.”4 In 1843, the German physiologist Emil du Bois-Reymond was able to detect voltage potential in resting muscles.5 In this early period of electricity development, the observations of physiologists studying the electrical workings in humans and animals proved helpful to engineers constructing the first practical electrical devices. The engineers’ work, in turn, provided helpful clues to the workings of the central nervous system. For example, the nervous system provided a useful model for building the telegraph, while the electric fish gave Volta ideas about how to build a battery. Du Bois-Reymond dedicated Animal Electricity, his 1848 book on electrical excitation in nerves and muscles, to Michael Faraday, whose “descriptions of induction in electrical circuits” provided useful analogies for describing excitation of nerves.6 In a public lecture delivered in 1851, du Bois-Reymond explained how the workings of the telegraph and other new electrical technology paralleled the way animals are constructed. He wrote:the wonder of our time, electrical telegraphy, was long ago modeled in the animal machine.

Every source of electric current remained transitory, produced by friction, heat, or induction from the release of accumulated charges in a Leyden jar. Little progress could be made unless some more continuous source of electricity was found. The long and winding road of discovery in this area began with Alessandro Volta, an unassuming physics professor who had been drawn to some experiments with animal electricity conducted by another professor, Luigi Galvani.26 During his research with frogs, Galvani had in 1780 stumbled onto an astonishing discovery: A dead frog’s leg convulsed when touched with a metal scalpel. This accidental observation lured Galvani into eleven years of research into the phenomenon before he published his findings. He concluded that the twitching resulted from a “nerveo-electrical fluid” that had accumulated in the muscle and apparently acted like a Leyden jar.

The first device to replenish an electrical charge through induction rather than friction, it became enormously popular. Volta became professor of physics at the University of Padua at thirty-seven, traveled widely, learned several languages, and won election to the Royal Society of London in 1791, the same year Galvani published his paper. By late 1793 Volta had rejected Galvani’s claim of “animal electricity,” believing that the source of electricity lay rather in the contact of two dissimilar metals during the experiment. Using one of his own inventions, the condensing electroscope, Volta systematically tested a variety of metal disks for their “electromotive force,” a term applied to electric current as opposed to static electricity.27 By measuring the amount of charge on each disk, Volta found that contact between zinc and copper left the latter with a positive charge and the former with a negative one.

The power of placebo The first medical patent issued under the Constitution of the United States was awarded in 1796 to a physician named Elisha Perkins, who had invented a pair of metal rods which he claimed could extract pains from patients. These tractors, as he dubbed them, were not inserted into the patient, but were merely brushed over the painful area for several minutes, during which time they would ‘draw off the noxious electrical fluid that lay at the root of suffering’. Luigi Galvani had recently shown that the nerves of living organisms responded to ‘animal electricity’, so Perkins’ tractors were part of a growing fad for healthcare based on the principles of electricity. As well as providing electrotherapeutic cures for all sorts of pains, Perkins claimed that his tractors could also deal with rheumatism, gout, numbness and muscle weakness. He soon boasted of 5,000 satisfied patients and his reputation was buoyed by the support of several medical schools and high-profile figures such as George Washington, who had himself invested in a pair of tractors.

He had four wives, all of them in separate houses, and he typically dropped in on one of them during his drives around the capital. “I keep my enemies guessing,” he said, brightening again. As Qaisi and I talked, a group of four Iraqi men sat down at a plastic table next to ours. One of them I recognized immediately: Hadi al-Amari, the head of the Badr Brigade, the very militia Qaisi believed had murdered his brother. Suddenly I felt an animal electricity in the air. Qaisi and Amari were eyeing each other. Qaisi stood up; so did Amari. I wondered if they were armed. “My friend,” Qaisi said, “it is so good to see you.” “Yes, it has been a long time,” Amari said. The two men embraced and kissed each other on their bearded cheeks. “We really must get together,” Amari said. “Yes, really, we must,” Qaisi said. THAT SAME SUMMER, I rode into the area of the Green Zone known as Little Venice.

One of the great stories of modern science tells of how, in June 1752, Franklin attached a metal key to the bottom of a dampened kite string and flew the kite in a storm. He luckily survived the electric shock because he was standing under an umbrella to keep dry! A few years later, in 1791, the Italian physician Luigi Galvani (1737–1798) conducted a series of experiments with frogs or, to be more precise, with frog’s legs. The experiments showed that when electricity passed through a dead frog’s legs they kicked. Galvani coined the term ‘animal electricity’. He had discovered bioelectricity. Galvani’s experiments were repeated by Alessandro Volta (1745–1827) – who later invented the electrical battery – and ignited the imagination of Europe. By the mid-nineteenth century, Emil du Bois-Reymond (1818– 1896), a German physician, had developed the galvanometer to measure electric currents in animals, frogs and humans. Using this new instrument, du Bois-Raymond discovered that electricity flowed along the nerves of the body.

Out of Africa by Karen Blixen

Here they squatted, — the old skeletons of men with tearing coughs and running eyes, the young slim smooth brawlers with black eyes and bruised mouths, and the mothers with their feverish children, like little dry flowers, hanging upon their necks. I often had bad burns to treat, for the Kikuyu at night sleep round the fires in their huts, and the piles of burning wood or charcoal may collapse and slide down on them, — when at times I had run out of my store of medicine, I found that honey was not a bad ointment for burns. The atmosphere of the terrace was animated, electric, like the atmosphere of the Casinos in Europe. The low lively flow of talk would stop when I came out, but the silence was pregnant with possibilities, now the moment had come when anything might happen. They did however always wait for me myself to choose my first patient. I knew very little of doctoring, just what you learn at a first aid course. But my renown as a doctor had been spread by a few chance lucky cures, and had not been decreased by the catastrophic mistakes that I had made.

Louis (1904), and Turin (1911).33 At the 1904 Electrical Congress in St. Louis, leading figures in electrical science, including the British inventor and engineer Colonel R. E. B. Crompton, Swedish Nobel Prize winner Svante Arrhenius, Lord Kelvin, and the American inventor Elihu Thomson, created the International Electrotechnical Commission (IEC). Their goal was to establish a representative body that could bring the “cooperative spirit that animates electrical workers” into a formal and permanent organization.34 As the IEC grew and matured in the early twentieth century, electrical scientists understood perfectly well that standards were not exclusively technical matters but rather technically oriented instances of diplomacy, with a heavy dose of international prestige and commercial power on the line.35 Taken together, the wide variety of standards developed for and inspired by electrical telegraphy illustrate the fundamental irony of standardization in the late nineteenth century: there was no standard way to make standards.

Until then, though, batteries had been something of a stagnant technology for nearly a hundred years. The first true battery was invented by the Italian scientist Alessandro Volta in 1799 in an effort to prove that his colleague Luigi Galvani had been wrong about frog power. Galvani had run currents of electricity through dead frogs’ nervous systems—the series of experiments that would inspire Mary Shelley’s Frankenstein—and had come to believe the amphibians had an internal store of “animal electricity.” He’d noticed that when he dissected a leg that was hung on a brass hook with an iron scalpel, it tended to twitch. Volta thought that his friend’s experiments were actually demonstrating the presence of an electrical charge running through the two different metal instruments via a moist intermediary. (They’d both turn out to be right—living muscle and nerve cells do indeed course with bioelectricity, and the fleshy frog was serving as an intermediary between electrodes.)

Father Divine, an African-American based in and around New York City, said he was God incarnate. The New York Times assumed his and his followers’ insanity: 16 OF DIVINE’S CULT SHOW MENTAL ILLS, one article was headlined; ONLY 2 OUT OF 18 OBSERVED AT BELLEVUE FOUND FREE OF WELL-DEFINED PSYCHOSES. McPherson, known as Sister Aimee, was a faith-healing, tongues-speaking Pentecostal divorcée preaching in a five-thousand-seat church in L.A. with a giant animated-electric-light billboard inside. After she went missing for five weeks in 1926, claiming she’d been kidnapped, Time described “her ‘disappearance,’ ” the way it referred to Billy Sunday’s “sermons,” with disparaging quotation marks. The bestselling novel of 1927 was Sinclair Lewis’s Elmer Gantry, a satire about a Billy Sunday–esque evangelist and his McPhersonian lover. In 1933 Time happily reported that “U.S. evangelists find their circles narrowing, embracing smaller and smaller towns.”

His aim was to produce “pain or fear” in the twins as a way of making the presence of adults “meaningful” and “rewarding” by comparison, as typical children might seek safety at their mother’s bedside after a bad dream. The results of these experiments were disappointing. Even when subjected to decibel levels capable of causing physical damage to the eardrum, Mike and Marty “remained unperturbed, particularly after the first two or three presentations.” Lovaas doubled down, turning to a method of punishment that had a long track record in behaviorist experiments on animals: electric shock. To head off any criticism for employing such harsh methods on preschool-age children, he added, “It is important to note, in view of the moral and ethical reasons which might preclude the use of electric shock, that their future was certain institutionalization.” He taped strips of metal foil to the floor of a room in his lab and wired these strips to a respectable-sounding device called a Harvard Inductorium—a modified Faraday coil that offered fine-tuning of its electrical output down to zero.
