In 1928, when London’s Society of Model Engineers received word that the Duke of York would be unable to open its annual exhibition, acting secretary W.H. Richards said, “Very well, I will find a substitute: it is a mechanical show, let us have a mechanical man to open it.”

So they did. Attendees that September were greeted by a robot named Eric who could stand up, bow, look left and right, deliver a four-minute opening address “with appropriate gestures,” and sit down. The speech, imparted by a radio signal, was described as “really sparkling” — apparently literally, as blue sparks shot from Eric’s teeth. From the Model Engineer and Light Machinery Review:

The Exhibition of 1928 has been one of the most successful we ever had. … The ‘Robot’ was a continuous attraction; he drew thousands of people to see his remarkable performance. … It is estimated that he rose and bowed to his audiences more than a thousand times during the week, and he not only amused the majority of his visitors, but positively amazed and bewildered them with his clever movements and conversation.

In 1929 Eric toured America, where he visited Harvard and MIT and informed interviewers that he did not gamble, drink, or run around at night. That’s reassuring, because eventually he disappeared — London Science Museum curator Ben Russell told the Telegraph, “No one quite knows what happened to him, whether he was blown up or taken to pieces for spare parts.” So, working from old photographs, the museum rebuilt him, and he appeared, debonair as ever, in a 2017 exhibition:

In the collection of the Smithsonian Institution is this 460-year-old automaton, a robot monk who walks in a square, beats his breast in contrition, raises a rosary and crucifix to his lips, turns and nods his head, rolls his eyes, and mouths obsequies. Its origin is not clear: The story goes that when the Spanish king’s son was ailing the relics of a Franciscan monk were brought to his side, and after he recovered the king commissioned the automaton in gratitude.

But no one really knows. “Many of the earliest automata were commissioned as expressions of religious belief: models of Jesus bled, automata of Satan roared and screamed, moving tableaux of biblical scenes were quite commonplace, coming to life for festivals and holy days,” writes historian E.R. Truitt in Ben Russell’s Robots: The 500-Year Quest to Make Machines Human. “Amazingly, no fewer than three mechanical monks survive: this one … and two more in Munich and Budapest, at the Deutsches Museum and Museum of Applied Arts respectively.”

When cattle buyers had trouble finding John Byron Plato’s farm, they gave up and went home. “That killed a mighty profitable bargain,” he told a reporter, which “got me thinking about rural addresses.” The buyers had left a note saying “it takes time to find your place.” Plato looked at his watch and saw that it “smiled back the answer.”

Plato’s “clock system” assigns numbers to directions — 12 is due north, 5 is southeast by south, and so on. Within each of these sectors, a location can be identified by its distance from the town center. “Thus if a man lived four miles west of his post office, his number would be 94 (nine for west and four for distance). If he lived two miles south, his number would be 62.” This could be refined further by adding one more character: 32T means “about 2.75 miles east of the post office.”

Plato claimed that this system could have led his lost cattle buyers to within a hundred yards of his house without a map or a compass. He published a series of “rural directories” using the clock system in western and central New York State in the 1920s and 1930s, but his business faded as the Depression pummeled agriculture, and the patent lapsed.

In a 1973 Scientific American article on bicycle technology, Oxford engineering lecturer S.S. Wilson showed that a man on a bicycle “improves his efficiency rating to No. 1 among moving creatures and machines”:

“When one compares the energy consumed in moving a certain distance as a function of body weight for a variety of animals and machines, one finds that an unaided walking man does fairly well (consuming about .75 calorie per gram per kilometer), but he is not as efficient as a horse, a salmon or a jet transport. With the aid of a bicycle, however, the man’s energy consumption for a given distance is reduced to about a fifth (roughly .15 calorie per gram per kilometer).”

11/18/2018 UPDATE: In 1974 the Austrian philosopher Ivan Illich wrote:

The model American male devotes more than 1,600 hours a year to his car. He sits in it while it goes and while it stands idling. He parks it and searches for it. He earns the money to put down on it and to meet the monthly installments. He works to pay for gasoline, tolls, insurance, taxes, and tickets. He spends four of his sixteen waking hours on the road or gathering his resources for it. And this figure does not take into account the time consumed by other activities dictated by transport: time spent in hospitals, traffic courts, and garages; time spent watching automobile commercials or attending consumer education meetings to improve the quality of the next buy. The model American puts in 1,600 hours to get 7,500 miles: less than five miles per hour. In countries deprived of a transportation industry, people manage to do the same, walking wherever they want to go, and they allocate only 3 to 8 per cent of their society’s time budget to traffic instead of 28 per cent.

In 1916 Manhattan chauffeur George Boyden patented a new way to navigate: Install a phonograph in your car to play audio recordings through a megaphone in front of the steering column. “The talking machine at the proper times will announce the directions whereby the driver will be enabled to follow a predetermined route.”

How does it know where you are? The phonograph is connected to the car’s wheels and will engage only when you’ve traveled certain predetermined distances. “For example, if it is desired to make a record to guide the driver from Chevy Chase to the Treasury Department, the record among other things would contain the directions ‘U street turn to the left,’ and knowing the distance between Chevy Chase and the corner of 18th and U, for example, [a record of this distance would be registered with the mechanism] and the desired direction spoken into the machine. From a cylinder prepared in this manner a matrix would be made for the production of permanent records.”

10/19/2018 UPDATE: A strikingly similar idea from 1971 (thanks, Alec):

I just thought this was clever: In 1880 Chicago inventor Samuel Gross proposed printing scales on the edges of a map’s reverse side, so the user could measure the distance between two points by turning up a corner.

“In this figure I have placed the scales on the two edges forming the angle at the lower right-hand corner; but it is evident that they may be placed on any one or more edges or parts thereof of the reverse side of the map, as may be preferred.”
