"Scientific Mating" on the cover of the April, 1924 issue of Science and Invention magazine

Online dating sites like eHarmony and OkCupid claim they can find you the perfect romantic match by using algorithms. These kinds of sites have catchy slogans like “date smarter, not harder,” implying that they’ve finally perfected a scientific approach to matchmaking. Just answer a few questions, and their super-secret love science will find the person who is right for you.

While much of the “science” behind online dating sites has been called into question, that doesn’t seem to dissuade us from wanting to make the messy (and often frustrating) world of romantic love into something quantifiable. This idea, of course, is nothing new—and at least one futurist thinker of the early 20th century hoped that new technological developments might one day create the perfect matchmaking device.

The April 1924 issue of Science and Invention magazine ran an article by Hugo Gernsback, the magazine’s publisher, which examined the different “scientific” ways to determine if a marriage will succeed or fail.

How much would the average man or woman give to know beforehand if his or her prospective married life is to be success or failure? At present, marriage is a lottery. It seems impossible to predict beforehand how your prospective mate will turn out in the future. Through certain fundamentals, which can easily be ascertained, one can be reasonably certain as to one’s choice. We take extreme care in breeding horses, dogs and cats, but when we come to ourselves we are extremely careless and do not use our heads nor the means that science puts in our hands for scientific breeding. There are certain basic tests which can be made today and which will give one a reasonable assurance of married happiness.

In the article Gernsback explains four different tests that can be administered to a couple in order to determine scientifically whether a marriage will work.

1) Physical Attraction Test

According to Gernsback, physical attraction is the single most important element for a successful marriage. He explains that in order to measure the level of a couple’s physical attraction for one another, electrodes must be attached to each person’s wrist so that an “electrical sphygmograph” can record their pulse. Then a chain is wrapped around their chests to measure breathing:

…around the chest of each is a chain which is secured to a piece of spring covered by a rubber hose. One end of the tube thus formed is sealed, the other connects to a manometer and also to a tambour supplied with a stylus. The stylus leaves a record on a moving paper tape showing the rate of respiration.

Essentially, if your pulse rate rises and you breathe more quickly while embracing or kissing your partner, Gernsback contends that this is scientific evidence of physical attraction.

2) Sympathy Test

The sympathy test involves one of the partners watching the other go through something mildly traumatic, like having blood drawn. In the illustration below, the young woman watches her partner and if her muscular contractions and sudden inhalations “due to excitement” are wild enough, then she’s supposed to be sufficiently sympathetic to him as a partner.

3) Body Odor Test

Interestingly, Gernsback claims that more marriages are probably wrecked by body odors than any other cause. During the body odor test, the couple is made to smell each other (“not a pleasant experience,” Gernsback opines) by one person being placed inside a large capsule with a hose coming out the top. The hose is led to the nose of the other person and if the smells aren’t found too objectionable (again, measured by devices strapped to the chest and wrist) then the romantic pairing is deemed safe.

4) Nervous Disorder Test

According to Gernsback it’s important that at least one partner can be calm under pressure. The nervous disorder test is perhaps the most amusing in that it imagines a man (let’s call him Professor Sixshooter) delivering a surprise gunshot in the air. The “nervous reaction” of both people is recorded on tape and if they both are too startled “marriage should not take place.” I don’t know about you, but I’d be a little uneasy if my partner wasn’t startled at the sound of a gunshot.

1966-67 AAA map of New York

Remember paper maps? They used to be the only game in town. But the 2000s (the aughts? have we named that decade yet?) saw a radical shift in the way that befuddled drivers could figure out how to get from point A to point B. Suddenly, global positioning systems (GPS) became affordable enough that the average consumer could buy stand-alone units for their cars and GPS technology began showing up in smartphones (though often early smartphones were simply using cell tower triangulation). It wasn’t very long ago that consumer GPS devices were super-futuristic technology.

The 1989 book Future Stuff by Malcolm Abrams and Harriet Bernstein looked at the various technologies that people might see in the 1990s and beyond. The book assigned an estimated year, an estimated price and gave the odds as to whether we’d see this technology at all. One of the technologies was “car video” navigation, as well as satellite navigation. The “video navigation system” relied on a rather primitive design—a “casette-tape data source” that allowed you to input an “electronic road map” on a video monitor mounted on your dashboard. The satellite navigation described in the book is much closer to what we actually see today:

Satellite navigation in the year 1998, as imagined in the 1989 book Future Stuff

The video navigation system, which we’ll see introduced early in the decade, should be passe by the end of the decade. It will be replaced by satellite navigation, an amazing system that will be able to pinpoint your car’s location anyplace in the world, alert you to an upcoming traffic jam and show you all alternate routes, warn you of approaching bad weather, and so on. Your car will be bouncing signals off satellites in space just like the most advanced communications systems.

Japan’s Nissan Motor Company is spearheading the technology with its Satellite Drive Information device. Your location will be shown on your car’s computer display screen, using Nissan’s Global Positioning System. Forget video road maps and memory banks. The picture on your screen will be the real thing transmitted via satellite. The display screen will even tell you where to make turns and also measure distances (to the next intersection or to your final destination).

Satellite navigation is going to make it difficult for someone even with the worst sense of direction to get lost.

So when did they think this technology would finally arrive? The authors predicted that it had a 70% chance of becoming a reality by 1998 and early models would cost $2,500 (about $4,340 adjusted for inflation). That prediction turned out to be fairly accurate. In 2000, a simple portable GPS device—which could indicate your current location—sold for $699. But the top-of-the-line portable GPS devices, which could provide driving directions, cost $2,799.

People tripping out in the February 28, 1960 edition of Closer Than We Think

Chemical warfare is nothing new. As early as 428 BC the Spartans were burning wood soaked in resin and sulfur for use against their enemies. And the First World War is often remembered for its horrific deaths due to mustard gas. But the mid-20th century ushered in a new futuristic chemical weapon: LSD.

Lysergic acid diethylamide (LSD), mescaline (peyote), and psilocybin (psychedelic mushrooms) were all seen as possible contenders for non-lethal weapons of the future; sprayed on an unsuspecting army or civilian population and making them vulnerable to invasion.

An Associated Press story from the September 6, 1959 Cedar Rapids Gazette in Iowa warned that the nuclear stalemate with the Soviet Union might prompt the Russians to develop chemicals that could be used against the United States. Americans scientists were said to have developed their own weapons to counter-attack.

Working in deep secrecy, U.S. scientists almost overnight have developed an arsenal of fantastic new weapons, variously known as psycho-chemicals and “madness” gases, which could virtually paralyze an enemy nation without firing a shot.

Interestingly, the article doesn’t name the chemicals, instead calling them “madness gases” or surgical anesthetics:

By way of definition, chemical warfare embraces the use of such compounds as the psycho-chemicals to create hallucinations in the enemy’s mind or the deadly nerve gases and other toxic substances to kill.

Some of the new chemicals act much faster than ether, the anesthetic used to put surgical patients to sleep, and have an effect lasting 24 to 48 hours. One means of dispersal is a newly developed “smoke ginny”  with which 2 men can lay a blanket of chemical fog over an area 5 miles long and 200 yards wide.

The February 28, 1960 edition of the Sunday comic strip “Closer Than We Think” by Arthur Radebaugh pulled this idea from the headlines and illustrated it in the picture above. The strip quotes Lt. Gen Arthur Trudeau from the U.S. Army as warning that the Soviets are developing weaponized versions of “psycho-chemicals” and that the U.S. should follow suit:

New nerve drugs may be used to immobilize whole cities or battle areas in tomorrow’s warfare.  The Chemical Corps knows about a complete arsenal of “nerve gases” that can make fighting men and embattled citizenry as happy and peaceable as kids playing tag.

Lt. Gen. Arthur Trudeau, chief of Army research and development, is worried about possible attacks with these drugs. He fears the United States might become a victim. “The Soviet [Union] has 15% of its munitions in chemicals,” he said. “I think psycho-chemicals are the coming weapon — we are missing out if we don’t capitalize on them.”

1981 vision of future chemical warfare, causing soldiers to hallucinate

The 1981 children’s book World of Tomorrow: War and Weapons by Neil Ardley also illustrated what a psycho-chemical attack might look like, with soldiers believing they’re being hunted by giant flying pterodactyl-like creatures:

This isn’t a scene from a science fiction story in which flying monsters take over the world. It is a view of a future battle as seen through the eyes of a defending soldier. He and his fellow troops reel back as invading aircraft fire shells containing chemicals. The chemicals are drugs that produce dream-like reactions or hallucinations in people. The soldiers see the aircraft turning into flying monsters and the buildings bend over, and they flee in terror. Invading forces protected from the effects of the drugs will soon arrive easily take over the city.

Careers of the future as illustrated by Cy DeCosse for the 1982 book, The Kids Whole Future Catalog

The Kids’ Whole Future Catalog touted itself as “a book about your future.” This 1982 book promised kids a peek into a coming era of automatic language translators, cities floating on the ocean and robot teachers. It also told kids about the kinds of jobs they’d have 30 years into the future. Well, 30 years have passed and it seems like as good a time as any to look back at their predictions.

Some of the predictions about which jobs would become obsolete are remarkably prescient. One of the predictions involves travel agents and stockbrokers, who are predicted to become scarce thanks to the home computer which allows people to make their own airline reservations and check stock prices. There’s even a prediction about jobs at the post office disappearing, as more and more people send mail through the computer.

What kind of job will you be working at 30 years from now? Do you expect to be programming computers or delivering mail? Can you imagine yourself as a stockbroker or a travel agent? Don’t be surprised if you end up in a totally different kind of career than the one you’re thinking of right now. In 30 years, some of today’s jobs may no longer exist. The computer will eliminate many of them. As more and more people send mail by computer, jobs at the post office will disappear. Stockbrokers’ and travel agents’ jobs may also become scarce. Instead of calling these experts, people will use their own home computers to check stock prices and make airline reservations. Today, computer programmers are in great demand, but in 30 years, they might not be. By then, many computers will be able to program themselves.

But don’t worry about find a future career. Although some kinds of work will no longer be available, new job opportunities will open up— in space industries, genetic engineering, undersea mining—maybe even robot psychology! Thirty years from now, you may be working at a job we can’t even imagine today.

Hugo Gernsback's vision for a monument devoted to electricity (1922)

In 1922, eccentric magazine publisher Hugo Gernsback decided that the world needed a 1,000-foot tall concrete monument to electricity. Gernsback imagined that this monument might last for thousands of years, and rather than some static behemoth stuck in time, the interior of his monument would be constantly changed to reflect the technological advances of each new generation.

Gernsback’s article in the October 1922 issue of Science and Invention magazine explained why electricity was worthy of a monument. Interestingly, he saw it as a message to future generations that even if our civilization should be wiped out by war or natural disasters, we were still able to accomplish something great at one time.

In connection with our editorial of this month, we show on this page a monument dedicated to the age in which we are living. Electricity, more than anything else, has made our present civilization what it is, and if this civilization should be wiped out by war or some other cataclysm, nothing would remain to tell what Electricity did for the race during the past century.

Before the Egyptians built their first pyramid they probably foresaw that unless they built something of a tremendous size it would not stand the ravages of man and Nature. Hence the size and form were chosen in such a way as to make it last for practically all time.

Gernsback explained that this monument would look like a gigantic electrical generator, 1,000 feet tall. By comparison, the Statue of Liberty is just 305 feet tall, and the Empire State Building (which was almost a decade away from being built in 1930) isn’t that much taller than the proposed monument, at just 1,250 feet if you don’t count its spire.

When we therefore propose to build a gigantic monument to Electricity, we have the same objects in mind. On some plateau we could erect an electrical generator, molded in concrete, 1,000 feet high. Molded of the finest concrete, such a monument would last for a thousand years. It would probably not be affected by the weather and the climate, and it is doubted whether it could be easily destroyed by any savage race that might come after us.

In the inside passages, along the walls, could be inscribed, in diagrams and otherwise, electrical fundamentals, from the first static machine down to the latest radio developments. As new inventions come about, these can be inscibed from year to year.

If the entire electrical industry would think well of such a plan, a monument of this kind could be built without taxing any one concern a great amount. It would be a lasting tribute to our race, and to the progress that is exemplified by Electricity.

Gernsback doesn’t suggest where such a monument might be built, but judging by the illustration, it could very well be in Smalltown, U.S.A. The illustration is by Frank R. Paul, who would help define the 1920s and ’30s pulp sci-fi era’s aesthetic. Four years later, in 1926, Gernsback began publishing Amazing Stories, the first magazine ever devoted solely to science fiction. Amazing Stories featured countless covers and story illustrations by Frank R. Paul, whose most famous illustration for the magazine appeared in 1927 for a reprint of H. G. Wells’ War of the Worlds.
