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
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.
