This is Scientific American’s Science Talk, posted on August 29th, 2020. I’m Steve Mirsky. And yesterday was the 175th anniversary of the publication of the first issue of Scientific American. Our current issue, the September issue, looks at the history of the magazine, from the content to how the word usage has changed to how the look has evolved. And on this episode of the podcast:


That’s former Scientific American editor-in-chief John Rennie. He gave a talk in 2008 to a group of New York City skeptics that went into some of our history. I’ve also prepared a segment about a handful of the dumber things we’ve done since 1845. And we’ll also hear a segment sponsored by the Kavli Prize with legendary astrophysicist Alan Guth. First, part of John Rennie’s talk, some of which ran as an episode of Science Talk back in 2008.

John Rennie:

Scientific American has been around since August 28th of 1845. It was just four pages long, four big newspaper-like pages; it had lots of old patent announcements and it had poetry, and it had little reports on science and all kinds of things about that…But, you know, having been around since 1845, this is a very long time obviously. This is around since basically about the beginning of the second industrial revolution. This is before the Civil War. This is so early that we know that Thomas Edison read it as a boy and we know Thomas Edison read it as a boy because he came to the offices of the editors and told them when he was demonstrating his invention of the phonograph for the first time. Having been around since 1845, I mean Scientific American has been around since before airplanes, since before automobiles, since before x-rays, since before relativity, obviously. It has been around since the discovery of the electrons; it has been around since before the germ theory of disease. It has been around for a very long time, but it has not been around longer than stupidity and that is something that at some level, the editors and writers for Scientific American have always dealt with during that very long history—and so I’m going to try to show you just a few highlights, or lowlights as the case may be, of some of Scientific American‘s experience with that.

The golden era of Scientific American‘s involvement with anything like skepticism was really back in the late teens–1920s; because during this time, Scientific American was involved with several different projects that were aimed at trying to debunk various things that were of questionable scientific accuracy. One of them had to do with a whole area; it looked very critically at different areas of medical quackery, and to that end, this is maybe one that they are probably most famous for. How many of you have ever heard of the electronic reactions of Abrams [ERA]? Not too many, probably. These days it’s not very well-known—take my word for it. However, at the time in the early 1920s, this was one of the major health fads sweeping the United States. It was founded by Dr. Albert Abrams, who came up with this radiological approach to diagnosis and ultimately treatment for disease, and it was so compelling, it was so attractive to a lot of the United States that it actually started to win over different practitioners and the AMA started to see it as a major threat; and they were mounting their own efforts to try to defeat the spread of the ERA. And Scientific American was pulled in to try to help debunk this as well and so, let’s start by just taking about the ERA itself. Dr. Abrams seems to have hit about something around 1916 or so; he seems to have had this idea for approaching diagnosis that involved a device that he called the dynamizer.

This is the magic of how the ERA actually worked. With the ERA, the patient would give a blood sample or could be a sample of pretty much anything indeed. Over time, it started to become something so liberal that it went from just blood or other body fluids to the point where Abrams was saying that you could take handwriting or just pictures of people, and that would be taken and would be inserted into the dynamizer. Then the wires from the dynamizer would then reach up and be attached to a healthy person, who would have to orient themselves facing west—because that was very important—and they would hold these things here and they would attach the other leads as necessary and then the practitioner would come up and would (tapping sounds), palpate this control person’s belly and listen (tapping sounds); and from the sounds, he could determine what was wrong with the person who had given the blood sample because, you see, this is going to be scientific. So some of you may want to, I guess, [if] you asked me to repeat this, I will, because it’s very complicated. The electronic resonances associated with the diseased Adams would migrate up through the wires and would alter the electronic resonances of this person and so the practitioner could then listen to this and could determine it.

Now, why was [it] that he didn’t just go and listen to the diseased person, I actually don’t know, even it’s not really clear; but this was great because Abrams would sell these boxes for like $400 to people who a[we]re licensed to become new ERA practitioners and the great thing was that part of the license was you were not for any reason allowed to open up the box and look inside. (laughs) Never could you look inside the box. And so, you know, he was selling this, he was also then selling different sorts of seminars, teaching people how to use the devices; he was minting money. He made millions of dollars in the early 1920s which was an appreciable sum of money. Oh! And this by the way: he didn’t just stop with diagnosis, he also moved on to the area of treatment because of course if you can use these resonances to diagnose what’s wrong, by reversing the polarity using a device called the oscilloclast, which is kind of an inverted dynamizer, he could then actually correct the resonances and fix whatever was wrong with you. And it was great.

I mean after awhile, he was just fixing pretty much anything with this and he was even being used to, at some point, identify where people might be. I mean, Abrams at one point didn’t stop short of actually taking a photograph of someone and using his dynamizer to look at a map and figure out where that person might be. Can you imagine why the health authorities thought this might actually be worth stopping? So Scientific American stepped into this and they undertook a nine-month investigation of the ERA, in which they painstakingly, laboriously looked at all the claims for it and treated it exactly the way; it was a model of investigation, because they basically said, “All right, Abrams would not cooperate with this, Abrams wanted nothing to do with it, but Scientific American found one practitioner who was willing to cooperate: Dr. X, as he is referred to in the magazine at the time, and Dr. X would consent to this.” And so Dr. X would say, “This is how ERA works, this is what you’re supposed to do”, and the panel of Scientific American put together would then say, All right, if that’s the case, well let’s try this.”

So they started them with this great test, in which they gave the ERA practitioner, Dr. X, they gave him a series of pure germ cultures in test tubes and basically said, “So here it is, this is the purified causative agent of these; it’s unlabeled, just tell us what this is.” Because if you can certainly diagnose if someone has, say, syphilis in their bodies from this processing of blood sample and if we give you pure germ culture, you should certainly be able to identify it that way. And Dr. X agreed that this was a good test, and he then deployed that and the results were actually amazing, because the results were that he didn’t get any of them right; he got all of them wrong. In fact, he actually—it was beyond what you would’ve imagined, that just [by] random chance you would’ve thought he would’ve gotten some of them right. Well Dr. X did not take this lying down, because he looked at it and said, “Oh! Here’s the problem. You see the labels that you’ve written as—some of them have red ink—well the redness of the labels is interfering with the resonance.”

So they changed that and they kept doing this. They kept doing this over and over again, month after month. Every time they would test it and [the] ERA would fail, then there was always some sort of excuse and they would correct for this and they would go back and do it again and again. And they eventually got to the point where they did somehow find a dynamizer, and they just tore it open and looked inside and they determined that the dynamizer inside was, as you would probably have imagined, a complete rat’s nest of just wires—and in some cases [they] weren’t connected to anything. It would just look complicated, if you even did peek inside. Some of them didn’t even connect to external leads on this thing.

So, after nine months, Scientific American finally came to its own conclusion on all of this. And their verdict—and this was part of a much longer article denouncing all of this—but as you can see, it basically said, “This committee finds that the claims advanced on behalf of the Electronic Reactions of Abrams and of electronic practice in general are not substantiated and it is our belief that they have no basis in fact. In our opinion, the so-called electronic reactions do not occur and the so-called electronic treatments are without value.” It was a model example of a kind of thing I think we could [would] all like to see, when it is possible to try to take some sorts of medical quackery and subject it to good skeptical scrutiny all the way through.

Scientific American was not always so successful in this regard. Because around the same time, another series of things that it was involved with was in looking at the spiritualism movement. Spiritualism [was] very, very big at the time—lots of séances were going on—and Scientific American undertook a competition in which they basically, they were promising two $2,500 prizes to any spiritual medium who could demonstrate certain things, of being able to demonstrate a physical manifestation to the satisfaction of the investigating board or could otherwise, I think, just show other sorts of proofs of this. And they went through for months after months, really years, looking at different mediums and just, you know, blowing them up. Harry Houdini was part of the team that would travel around with Scientific American. I don’t believe that Arthur Conan Doyle was actually part of this, because of course he was little soft on the subject of spiritualism, but he was involved with this a lot as well, and there was one editor, Malcolm Bird, who was—wonderfully named, Malcolm Bird—who was the managing editor of Scientific American at the time, and it’s pretty clear when you read back through the accounts that they wrote of their attempts to bust these different séances, that Bird was kind of sympathetic to the spiritualist cause. It was pretty clear that he actually in lot of cases, really wanted to find a ghost in some of these; however, the board that they put together, the panel they would send to these séances never, you know, they found what they found—they kept finding fraud after fraud.

This all came to a head however, when it eventually came to look[ing] at the case of a famous spirit medium whose name was Mina Crandon, but she was generally referred to as Margery. This became sort of the downfall of Scientific American‘s ghost-busting crusade, because Margery was, you know; she would have these various meetings in which she would just seemingly just would show amazing things and prove that she has had amazing contact with the spirit world, often through the medium of Walter—Walter who was the male voice who would speak through her at these times. People were really quite impressed with the job that she was doing and apparently—now this is something I’m getting directly from Penn Jillette himself, because when he was telling the story back at the amazing meeting last year, Penn Jillette was actually able to elaborate on this because he had met and interviewed the granddaughter of Mina Crandon and the granddaughter was able to confirm certain things—Mina was kind of a looker, particularly by the times, and apparently she would do a lot of her séances in the nude. (laughs) This may have sort of softened some of the skepticism (laughs) that was associated with this and that may in fact have actually affected [the investigation]. When Scientific American‘s investigative team showed up and actually started living in the Crandon’s house in Boston, Malcolm Bird is just transfixed with Mina; he just thinks she’s great.

When you read those accounts, he is strongly believing that he has finally, finally found the genuine article, and again, I would only cite what Penn Jillette told me about this: that apparently, according to Margery’s granddaughter, yes, she really was sleeping with all of them, which was convenient—not for Scientific American, however. Because Scientific American was well on its way toward forking over those $5,000 in prize money. But then it was prepared to do this, while Harry Houdini who was properly part of the team, was not there; he was off on tour and he heard about the fact. He was reading that it looked like Scientific American was closing in on doing this, and so he rushed back so he could be there for another séance that involved all of them, and he’s there for the séance. He is very upset that Malcolm Bird and other members of the panel seemed ready to award this, and in the middle of the séance at one point Harry Houdini, leaks [leaps] to his feet and points to some evidence of fakery, and he is denouncing her right in the middle of it. And Malcolm Bird leaks [leaps] to his feet and starts to vigorously defend Mina’s honor, which lead[s] to what I get the impression was then a fistfight of some sort (laughs) that broke out between Harry Houdini and Malcolm Bird; and I think it is probably an excess of my own imagination that imagines [the fight] spilling out into the street somehow, because I really can’t imagine that in a fistfight between Harry Houdini and Malcolm Bird that it would last very long. However, it was enough to pretty much destroy the ghost-busting attempts of Scientific American at that point. So we never actually gave out the $5,000 in prizes. Yay!

Steve Mirsky:

John Rennie was the seventh editor in chief in Scientific American history. He’s now at Quanta Magazine. It’s been my great good fortune to be at SciAm during his tenure as well as his successors, Mariette DiChristina, now dean of the College of Communications at Boston University, and the recently arrived Laura Helmuth, late of the Washington Post.

Alan Guth is also part of Scientific American’s history. In 1984, he and Paul Steinhardt published a seminal article titled The Inflationary Universe. Here’s a short segment, about six minutes, with Guth, sponsored by the Kavli Prize.


In 2009 Guth was part of a panel discussion at the annual meeting of the American Association for the Advancement of Science. I ran highlights of that roundtable on this podcast. Just search for “Stars of Cosmology” parts 1 and 2 to get his and his colleagues’ thoughts on the state of cosmology.

In 175 years you make some errors. And in the current issue of the magazine, the September issue, there’s an article that holds our own feet to the fire about some of the more important errors that this publication has made in the last 175 years. I, on the other hand, took a few minutes to research some of the less important errors we’ve made in the last 175 years.

Way back in 1846, we shared a terrible notion about boat propellers. “It is truly astonishing,” we wrote, “that men of capital in England persist in keeping themselves so totally ignorant of the plain philosophical principles of Mechanics, as to suppose that a propeller of any form on the screw principle, can compete with the simple Fultonian paddle-wheel.” What we missed was that as a ship rolls, more of one side of the paddle is submerged, causing that side to put out more power. The steering issue that results is just one reason for the lack today of paddle-driven aircraft carriers. Our original take on propellers was clearly a bad spin.

In 1869 we had ideas for a better way to get between Manhattan and Brooklyn than by a suspension bridge. “J. W. Morse has devised a bridge which permits of a much lighter construction than a normal suspension bridge and is, consequently, much cheaper to build. Mr. Morse’s project provides for transportation across the river in a giant platform, suspended by means of cables from a trolley running upon a gantry across the river…the fact that the traveler hangs only 3 feet above the water—and hence is almost at street-level—makes it easy for heavily loaded wagons to cross the river, and will also be appreciated by the workman returning home on foot after a hard day’s toil in the factory or warehouse.” As far as I’m concerned, if there’s anything worse than being 130 feet above the East River it’s being 3 feet above the East River.

As you heard from John Rennie, Scientific American in the 1920’s was enthusiastic about debunking séance holders who claimed to communicate with the dead. But in 1923 we advocated that some mediums—not “the blatant fraud who swindles widows out of their insurance money through ‘messages’ from their deceased husbands”—should get compensated for their services. “For after all, even a medium must live. Nobody has ever suggested that the doctor ought to have a job, on the side, as carpenter or hack driver, earning his living from this and giving such time as he can spare from it to the gratuitous healing of disease…the medium, to the people he serves, gives just as real a service as does the doctor…why ask him to give it for nothing?” A century later, we here at Scientific American are all out of even any small medium largesse.

We weren’t all that worried about our own income either, at least in 1849. In May of that year we apologized to the readership for bombarding them with two-and-a-half columns of ads. In the entire issue. In 1915 we took stock and set forth a stance we still maintain, “Time and the increasing importance of advertising in modern journalism changed that haughty attitude.”

It’s 2020 and we still don’t have flying cars. (And if human beings’ driving ability on the ground is any indication, thank goodness.) But back in 1915 we were looking forward to transparent planes: “Military authorities await with great interest the development of the new French invisible aeroplane…over the [aluminum] framework, instead of canvas, is stretched a transparent material…called ‘cellon,’…a chemical combination of cellulose and acetic acid. Of almost the same transparency as glass, it does not crack or splinter and has the toughness and pliability of rubber.” Which is true. And which is why it’s used today for eyeglass frames. Of course, we can’t say for sure that there are no French invisible airplanes.

In 1913, we reported on the discovery of the fossil skull from that came to known as Piltdown Man: “In Piltdown Common, Sussex, England, an English paleontologist, Mr. Dawson, discovered, about a year ago, a fairly complete human skull representing the most ancient relic of the human race in the British Isles, and one of the oldest found anywhere.” And two years later we ran a scholarly analysis of the find, by Professor W.P. Pycraft of the British Museum. In that piece, titled Mankind in the Making: The Direct Ancestor of the Modern Man and What He Looked Like, Pycraft wrote, “While the skull is essentially human, that is to say, it is the skull of a member of the genus Homo, though representing a man of low grade, the jaw, on the other hand, as we have already remarked, is almost that of an ape.” Piltdown Man was eventually revealed to be a hoax, made of parts of a human skull and an orangutan jaw—when Pycraft said the jaw was “almost that of an ape” he was almost right.     

Finally, in 1883 we thought that nobody would really want telephones: “Despite the fact that recent experiments have demonstrated the possibility of telephoning over long circuits, it is to be doubted if the instrument will be used otherwise than locally…there is no system of signals as clear as the present Morse code, as interpreted by the sounder…by telephone, it is the sound of a word and not its vowel and consonants which the operator receives and a mistake can easily happen even out of the best conditions.” Well, yes, that’s why the game is called telephone. Actually, we might ultimately have been somewhat right—with the advent of texting many of us apparently prefer those mini-telegrams to talking. As comedian Gary Gulman put it, “To me the phone is just this seldom-used app on my phone.”
