Dacey’s Patent Automatic Nanny Documented by Ted Chiang

The Automatic Nanny was the creation of Reginald Dacey, a mathematician born in London in 1861. Dacey’s original interest was in building a teaching engine; inspired by the recent advances in gramophone technology, he sought to convert the arithmetic mill of Charles Babbage’s proposed Analytical Engine into a machine capable of teaching grammar and arithmetic by rote. Dacey envisioned it not as a replacement for human instruction, but as a labor-saving device to be used by schoolteachers and governesses.

For years, Dacey worked diligently on his teaching engine, and even the death of his wife, Emily, in childbirth in 1894 did little to slow his efforts.

What changed the direction of his research was his discovery, several years later, of how his son, Lionel, was being treated by the nanny, a woman known as Nanny Gibson. Dacey himself had been raised by an affectionate nanny, and for years assumed that the woman he’d hired was treating his son in the same way, occasionally reminding her not to be too lenient. He was shocked to learn that Nanny Gibson routinely beat the boy and administered Gregory’s Powder (a potent and vile-tasting laxative) as punishment. Realizing that his son actually lived in terror of the woman, Dacey immediately fired her. He carefully interviewed several prospective nannies afterwards, and was surprised to learn of the vast range in their approaches to child-rearing. Some nannies showered their charges with affection, while others applied disciplinary measures worse than Nanny Gibson’s.

Dacey eventually hired a replacement nanny, but regularly had her bring Lionel to his workshop so he could keep her under close supervision. This must have seemed like paradise to the child, who demonstrated nothing but obedience in Dacey’s presence; the discrepancy between Nanny Gibson’s accounts of his son’s behavior and his own observations prompted Dacey to begin an investigation into optimal child-rearing practices. Given his mathematical inclination, he viewed a child’s emotional state as an example of a system in unstable equilibrium. His notebooks from the period include the following: “Indulgence leads to misbehavior, which angers the nanny and prompts her to deliver punishment more severe than is warranted. The nanny then feels regret, and subsequently overcompensates with further indulgence. It is an inverted pendulum, prone to oscillations of ever-increasing magnitude. If we can only keep the pendulum vertical, there is no need for subsequent correction.”

Dacey tried imparting his philosophy of child-rearing to a series of nannies for Lionel, only to have each report that the child was not obeying her. It appears not to have occurred to him that Lionel might behave differently with the nannies than with Dacey himself; instead, he concluded that the nannies were too temperamental to follow his guidelines. In one respect, he concurred with the conventional wisdom of the time, which held that women’s emotional nature made them unsuitable parents; where he differed was in thinking that too much punishment could be just as detrimental as too much affection. Eventually, he decided that the only nanny that could adhere to the procedures he outlined would be one he built himself.

In letters to colleagues, Dacey offered multiple reasons for turning his attention to a mechanical nursemaid. First, such a machine would be radically easier to construct than a teaching engine, and selling them offered a way to raise the funds needed to perfect the latter. Second, he saw it as an opportunity for early intervention: by putting children in the care of machines while they were still infants, he could ensure they didn’t acquire bad habits that would have to be broken later. “Children are not born sinful, but become so because of the influence of those whose care we have placed them in,” he wrote. “Rational child-rearing will lead to rational children.”

It is indicative of the Victorian attitude toward children that at no point does Dacey suggest that children should be raised by their parents. Of his own participation in Lionel’s upbringing, he wrote, “I realize that my presence entails risk of the very dangers I wish to avoid, for while I am more rational than any woman, I am not immune to the boy’s expressions of delight or dejection. But progress can only occur one step at a time, and even if it is too late for Lionel to fully reap the benefits of my work, he understands its importance. Perfecting this machine means other parents will be able to raise their children in a more rational environment than I was able to provide for my own.”

For the manufacture of the Automatic Nanny, Dacey contracted with Thomas Bradford & Co., maker of sewing and laundry machines. The majority of the Nanny’s torso was occupied by a spring-driven clockwork mechanism that controlled the feeding and rocking schedule. Most of the time, the arms formed a cradle for rocking the baby. At specified intervals, the machine would raise the baby into feeding position and expose an India-rubber nipple connected to a reservoir of infant formula. In addition to the crank handle for winding the mainspring, the Nanny had a smaller crank for powering the gramophone player used to play lullabies; the gramophone had to be unusually small to fit within the Nanny’s head, and only custom-stamped discs could be played on it. There was also a foot pedal near the Nanny’s base used for pressurizing the waste pump, which provided suction for the pair of hoses leading from the baby’s rubber diaper to a chamber pot.

The Automatic Nanny went on sale in March 1901, with an advertisement appearing in the Illustrated London News (shown on the next page).

It is worth noting that, rather than promoting the raising of rational children, the advertising preys on parents’ fears of untrustworthy nursemaids. This may have just been shrewd marketing on the part of Dacey’s partners at Thomas Bradford & Co., but some historians think it reveals Dacey’s actual motives for developing the Automatic Nanny. While Dacey always described his proposed teaching engine as an assistive tool for governesses, he positioned the Automatic Nanny as a complete replacement for a human nanny. Given that nannies came from the working class, while governesses typically came from the upper class, this suggests an unconscious class prejudice on Dacey’s part.

Whatever the reasons for its appeal, the Automatic Nanny enjoyed a brief period of popularity, with over 150 being sold within six months. Dacey maintained that the families that used the Automatic Nanny were entirely satisfied with the quality of care provided by the machine, although there is no way to verify this; the testimonials used in the advertisements were likely invented, as was customary at the time.

What is known for certain is that in September 1901, an infant named Nigel Hawthorne was fatally thrown from an Automatic Nanny when its mainspring snapped. Word of the child’s death spread quickly, and Dacey was faced with a deluge of families returning their Automatic Nannies. He examined the Hawthornes’ Nanny, and discovered that the mechanism had been tampered with in an attempt to enable the machine to operate longer before needing to be rewound. He published a full-page ad, in which—while trying not to blame the Hawthorne parents—he insisted that the Automatic Nanny was entirely safe if operated properly, but his efforts were in vain. No one would entrust their child to the care of Dacey’s machine.

To demonstrate that the Automatic Nanny was safe, Dacey boldly announced that he would entrust his next child to the machine’s care. If he had successfully followed through with this, he might have restored public confidence in the machine, but Dacey never got the chance, because of his habit of telling prospective wives of his plans for their offspring. The inventor framed his proposal as an invitation to partake in a grand scientific undertaking, and was baffled that none of the women he courted found this an appealing prospect.

After several years of rejection, Dacey gave up on trying to sell the Automatic Nanny to a hostile public. Concluding that society was not sufficiently enlightened to appreciate the benefits of machine-based child care, he likewise abandoned his plans to build a teaching engine, and resumed his work on pure mathematics. He published papers on number theory and lectured at Cambridge until his death in 1918, during the global influenza pandemic.

The Automatic Nanny might have been completely forgotten were it not for the publication of an article in the London Times in 1925, titled “Mishaps of Science.” It described in derisive terms a number of failed inventions and experiments, including the Automatic Nanny, which it labeled “a monstrous contraption whose inventor surely despised children.” Reginald’s son, Lionel Dacey, who by then had become a mathematician himself and was continuing his father’s work in number theory, was outraged. He wrote a strongly worded letter to the newspaper, demanding a retraction, and when they refused, he filed a libel suit against the publisher, which he eventually lost. Undeterred, Lionel Dacey began a campaign to prove that the Automatic Nanny was based on sound and humane child-rearing principles, self-publishing a book about his father’s theories on raising rational children.

Lionel Dacey refurbished the Automatic Nannies that had been in storage on the family estate, and in 1927 offered them for commercial sale again, but was unable to find a single buyer. He blamed this on the British upper class’s obsession with status; because household appliances were now being marketed to the middle class as “electric servants,” he claimed upper-class families insisted on hiring human nannies for appearance’s sake, whether they provided better care or not. Those who worked with Lionel Dacey blamed it on his refusal to update the Automatic Nanny in any way; he ignored one business advisor’s recommendation to replace the machine’s spring-driven mechanism with an electric motor, and fired another who suggested marketing it without the Dacey name.

Like his father, Lionel Dacey eventually decided to raise his own child with the Automatic Nanny, but rather than look for a willing bride, he announced in 1932 that he would adopt an infant. He did not offer any updates in the following years, prompting a gossip columnist to suggest that the child had died at the machine’s hands, but by then there was so little interest in the Automatic Nanny that no one ever bothered to investigate.

The truth regarding the infant would never have come to light if not for the work of Dr. Thackery Lambshead. In 1938, Dr. Lambshead was consulting at the Brighton Institute of Mental Subnormality (now known as Bayliss House) when he encountered a child named Edmund Dacey. According to admission records, Edmund had been successfully raised using an Automatic Nanny until the child was two years old, the age at which Lionel Dacey felt it appropriate to switch him to human care. He found that Edmund was unresponsive to his commands, and shortly afterwards, a physician diagnosed the child as “feebleminded.” Judging such a child an unsuitable subject for demonstration of the Nanny’s efficacy, Lionel Dacey committed Edmund to the Brighton Institute.

What prompted the institute’s staff to seek Dr. Lambshead’s opinion was Edmund’s diminutive stature: although he was five, his height and weight were that of the average three-year-old. The children at the Brighton Institute were generally taller and healthier than those at similar asylums, a reflection of the fact that the institute’s staff did not follow the still-common practice of minimal interaction with the children. In providing affection and physical contact to their charges, the nurses were preventing the condition now known as psychosocial dwarfism, where emotional stress reduces a child’s levels of growth hormones, and which was prevalent in orphanages at the time.

The nurses quite reasonably assumed that Edmund Dacey’s delayed growth was the result of substituting the Automatic Nanny’s mechanical custody for actual human touch, and expected him to gain weight under their care. But after two years as a resident at the institute, during which the nurses had showered attention on him, Edmund had scarcely grown at all, prompting the staff to look for an underlying physiological cause.

Dr. Lambshead hypothesized that the child was indeed suffering from psychosocial dwarfism, but of a uniquely inverted variety: what Edmund needed was not more contact with a person but more contact with a machine. His small size was not the result of the years he spent under the care of the Automatic Nanny; it was the result of being deprived of the Automatic Nanny after his father felt he was ready for human care. If this theory were correct, restoring the machine would cause the boy to resume normal growth.

Dr. Lambshead sought out Lionel Dacey to acquire an Automatic Nanny. He gave an account of the visit in a monograph written many years later:

[Lionel Dacey] spoke of his plans to repeat the experiment with another child as soon as he could ensure that the child’s mother was of suitable stock. His feeling was that the experiment with Edmund had failed only because of the boy’s “native imbecility,” which he blamed on the child’s mother. I asked him what he knew of the child’s parents, and he answered, rather too forcefully, that he knew nothing. Later on, I visited the orphanage from which Lionel Dacey had adopted Edmund, and learned from their records that the child’s mother was a woman named Eleanor Hardy, who previously worked as a maid for Lionel Dacey. It was obvious to me that Edmund is, in fact, Lionel Dacey’s own illegitimate son.

Lionel Dacey was unwilling to donate an Automatic Nanny to what he considered a failed experiment, but he agreed to sell one to Dr. Lambshead, who then arranged to have it installed in Edmund’s room at the Brighton Institute. The child embraced the machine as soon as he saw it, and in the days that followed he would play happily with toys as long as the Nanny was nearby. Over the next few months, the nurses recorded a steady increase in his height and weight, confirming Dr. Lambshead’s diagnosis.

The staff assumed that Edmund’s cognitive delays were congenital in nature, and were content as long as he was thriving physically and emotionally. Dr. Lambshead, however, wondered if the consequences of the child’s bond with a machine might be more far-ranging than anyone suspected. He speculated that Edmund had been misdiagnosed as feebleminded simply because he paid no attention to human instructors, and that he might respond better to a mechanical instructor. Unfortunately, he had no way to test this hypothesis; even if Reginald Dacey had successfully completed his teaching engine, it would not have provided the type of instruction that Edmund required.

It was not until 1946 that technology advanced to the necessary level. As a result of his lectures on radiation sickness, Dr. Lambshead had a good relationship with scientists working at Chicago’s Argonne National Laboratory, and was present at a demonstration of the first remote manipulators, mechanical arms designed for the handling of radioactive materials. He immediately recognized their potential for Edmund’s education, and was able to acquire a pair for the Brighton Institute.

Edmund was thirteen years old at this point. He had always been indifferent to attempts by the staff to teach him, but the mechanical arms immediately captured his attention. Using an intercom system that emulated the low-fidelity audio of the original Automatic Nanny’s gramophone, nurses were able to get Edmund to respond to their voices in a way they hadn’t when speaking to him directly. Within a few weeks, it was apparent that Edmund was not cognitively delayed in the manner previously believed; the staff had merely lacked the appropriate means of communicating with him.

With news of this development, Dr. Lambshead was able to persuade Lionel Dacey to visit the institute. Seeing Edmund demonstrate a lively curiosity and inquisitive nature, Lionel Dacey realized how he had stunted the boy’s intellectual growth. From Dr. Lambshead’s account:

He struggled visibly to contain his emotion at seeing what he had wrought in pursuit of his father’s vision: a child so wedded to machines that he could not acknowledge another human being. I heard him whisper, “I’m sorry, Father.”

“I’m sure your father would understand that your intentions were good,” I said.

“You misunderstand me, Dr. Lambshead. Were I any other scientist, my efforts to confirm his thesis would have been a testament to his influence, no matter what my results. But because I am Reginald Dacey’s son, I have disproved his thesis twice over, because my entire life has been a demonstration of the impact a father’s attention can have on his son.”

Immediately after this visit, Lionel Dacey had remote manipulators and an intercom installed in his house and brought Edmund home. He devoted himself to machine-mediated interaction with his son until Edmund succumbed to pneumonia in 1966. Lionel Dacey passed away the following year.

The Automatic Nanny seen here is the one purchased by Dr. Lambshead to improve Edmund’s care at the Brighton Institute. All the Nannies in Lionel Dacey’s possession were destroyed upon his son’s death. The National Museum of Psychology thanks Dr. Lambshead for his donation of this unique artifact.
