Fritz Kahn: The Little-Known Godfather of Infographics

By:

How a German gynecologist transformed science into visual poetry and laid the foundations of modern information graphics.

Around the time when Austrian sociologist, philosopher, and curator Otto Neurath was building his ISOTYPE visual language, which laid the foundation for pictogram-based infographics, another infographic pioneer was doing something even more ambitious: The German polymath Fritz Kahn — amateur astronomer, medical scientist by training, gynecologist by early occupation, artist by inclination, writer, educator and humanist by calling — was developing innovative visual metaphors for understanding science and the human body, seeking to strip scientific ideas of their alienating complexity and engage a popular audience with those essential tenets of how life works. Best-known today for his iconic 1926 poster Man as Industrial Palace, Kahn inspired generations of scientific illustrators, including such legends as Irving Geis and such cultural treasures as the 1959 gem The Human Body: What It Is And How It Works. His influence reverberates through much of our present visual communication and today’s best infographics .

Fritz Kahn (1888–1968)

Now, visual culture powerhouse Taschen has captured the life’s work of this infographic pioneer in the magnificent monograph Fritz Kahn (public library) — a 6-pound tome in English, French and German that collects and contextualizes his most influential images and essays and, above all, celebrates a boundless mind that never settled for limiting itself to a single discipline, to any one area of curiosity, to the onus and hubris of specialization that our culture so vehemently and so toxically fetishizes.

In the introduction, the prolific design historian and writer Steven Heller calls Kahn and Neurath “two sides of the same pie chart,” despite the fact that they likely never met:

Each passionately sought to devise a distinct graphic design language to replace the jargon and lay waste to an ever-growing Tower of Babel.

Like Neurath, who didn’t actually create the symbols he became known for, Kahn was not an artist himself but compensated for it with the potent combination of his powers of logic and his ability to surround himself with top talent, who would execute his visions while also expanding his taste and visual literacy. Though his innovative methods were themselves a force to be reckoned with, the underlying impetus was as simple as it was profound: Kahn was just a brilliant science communicator who sought to engage the public’s imagination in popularizing science. He used his infographics as Carl Sagan did narrative and the moving image, subverting the medium — and subverting it masterfully — to the goals of the message. Heller writes:

His graphic design preferences were eclectic and included such methods as photo-collage, painting and drawing and styles like comic, surrealist, dada and more. The art of analogy was Kahn’s forte (sometimes to the extreme): he might compare an ear with a car or a bird’s feather with railroad tracks, all meant to explain ever more impenetrable phenomena by means which triggered the viewer’s imagination. Kahn employed whatever visual trick he could cobble together for the end result: popular comprehension.

[…]

The legacy of Kahn’s work has resonance now and will continue into the future.

'Man as Industrial Palace,' 1926

But how did Kahn come to shape culture so profoundly? Editors Uta von Debschitz and Thilo von Debschitz write in the introduction:

In the first decades of the 20th century, Berlin was the center for a huge variety of political, social and cultural energies, which in their explosive interaction unleashed among other things a firework display of new aesthetic forms. Fritz Kahn combined some of these innovative texts and pictorial forms into a popular scientific “overall painting of man in the light of modern science.” The work, entitled The Life of Man (1922–31), contains so many highly expressive verbal and pictorial metaphors that one reviewer said Kahn was inclined “to illustrate every statement within a picture that knocks a hole in the skull of even the most slow-witted reader” — an opening for new insights and options.

It’s rather telling that even that reviewer used such a visceral bodily metaphor to convey a conceptual idea — it was precisely in enlisting the physical to explain the metaphorical that Kahn found his greatest power. As a scientist, he understood the visual bias of our brains; as an artistically minded design-thinker, he knew how powerfully graphics could convey ideas and ideologies; as a man of medicine, he grasped the importance of visualizing the body to illuminate its inner workings.

What goes on in our heads when we see a car and say 'car' (1939)

'Daily hair growth: the human body produces 100 feet of hair substance every day. If all this growth were to converge into one single hair, that hair would grow by one inch every minute.' (1929)

Kahn was also keenly aware of the importance of pictures in education. He trawled textbooks and scientific journals for material to use in his famous “man book,” but he enlisted his artists and the design department of his publishing house in infusing the images with more life, more vibrancy, greater calls to the imagination. He developed a style based on architectural and industrial visual metaphors and began depicting the human body as a series of modern workplaces, with each organ and organ-system operated by different machines, control panels, and circuits, as in his famous Man as Industrial Palace, seeking “to depict the most important processes of life, which can never be observed directly, in the form of familiar technical processes.” (Bear in mind, he was working long before some of the most now-fundamental notions in modern science were known, decades before even the discovery of DNA.)

'The speed of thought — overtaken by technology!' (1939)

But Kahn was far from reducing a human being to mere machinery. The von Debschnitz write:

His factories, engine-rooms and laboratories do not work on their own, but are operated and driven by large numbers of workers. These human figures make visible certain activities of individual cells or organs, but they also stand for life itself, which keeps the “man machine” running. In Kahn’s pictorial world there is plenty of room alongside the demonstrable for the unconscious, the unfamiliar and the intangible. He sees metaphysics and science not as opposites but as two sides of the same coin, as the “heaven and earth of the human soul.”

'The five points in common between muscle operation and an electric doorbell circuit: (1) volition — bell button, (2) motor center — battery, (3) nerve — wire, (4) motor end-plate — interpreter, (5) muscle — clapper.' (1924, 1927)

'The cycle of matter and energy' (1926)

Kahn could also be considered a pioneer of interactive storytelling long before the technologies of interaction existed. He transformed the pictorial image from a static object to passively behold to an active invitation to engage, reimagine, and connect:

Kahn’s conceptual illustrations inverted the text-image relationship that had prevailed until then. The picture took prominence and switched from observed object to active agent, opening up new imaginary spaces for the viewer. It challenged the viewer to explore these spaces independently, to find [his or her] place in them, and develop new perspectives from there — a life-saving ability in a crisis-torn age like that of [the world war].

[…]

Apart from instruction and entertainment, edification is another important function of the illustrated factual book. Meaning, comfort, fresh perspectives, and ideally a faith that can move mountains, often form in reaction to a strong aesthetic impulse — for example, in the borderland between science and art. Kahn knew the healing effect of the “imagination” from personal and medical experience, especially in relation to observing the macro- or microcosm. … Verbal and visual images can help man (re)connect with himself, his group, the world and the universe, to find his way or place.

In a twist of tragic irony, Kahn himself followed the fate of many Jewish intellectuals and was forced to flee Germany when the Nazis took power. His books were confiscated, banned and burned, and put on a list of “damaging and undesirable writing.” His images, however, remained in use thanks to blatant plagiarism — worst of all, the science journal editor and self-professed Nazi Gerhard Venzmer ripped off Kahn’s “man book” in a similar edition that featured an extra chapter on “racial studies and racial care,” full of the expected bigoted atrocities. Fortunately, Kahn was able to sue for copyright after the end of WWII and won the case — but the experience demonstrated both the power of his images and the challenging cultural context in which he created them.

'Travel experiences of a wandering cell: the villi currents of the intestinal tract.' (1924)

Above all, however, Kahn was a kind of scientific poet who enlisted the tenets of literature and the arts in making scientific ideas not only accessible but exciting. One of the most beautiful examples of this comes from his 1924 article for the journal Kosmos, titled “Fairy-tale Journey on the Bloodstream.” In it, he extols “the drama which, since its discovery 200 years ago, has repeatedly stirred the ecstasy of all who have seen it: the circulation of the blood” and writes — sings, almost:

“What a drama, but alas, only a drama!” The microscope’s field of vision is narrowly limited and we see the blood cells arriving on one side and disappearing again on the other… where from? where to? — we don’t know […]. The researcher stops at the rigid circle of his microscope’s field of vision, but we, we are poets, and who will forbid the imagination to travel to magical realms over lands and over seas like the child with the seven swans? […] Like the hero of the “last fairy-tale” we become smaller and smaller until at last we stand microscopically tiny, mini-Lilliputians on the bank of the vein-stream, and see the cells drifting past us, as big as the barques [large sailing ships] of men. We climb up one of the cliffs that loom into the stream, and wait. Cell after cell swims past, but quick and in the middle of the stream, unattainable to our desires. At last, however, a cell-boat drifts close to us on the beach, settles askew like a ship run aground, we leap across and into it, now it tilts from side to side, we push off and sail away. We are sailing! In our cell-boat on the red-gold stream of blood! Farewell, realm of man! We are in the land of fairy-tales, the fairy-tale land of truth, above which you rough giants gap blithely away on your great feet, and we sail towards miracles, true miracles!

Fritz Kahn is itself a miracle of human imagination, wholeheartedly recommended.

How to Be an Educated Consumer of Infographics: David Byrne on the Art-Science of Visual Storytelling

By:

Cultivating the ability to experience the “geeky rapture” of metaphorical thinking and pattern recognition.

As an appreciator of the art of visual storytelling by way of good information graphics — an art especially endangered in this golden age of bad infographics served as linkbait — I was thrilled and honored to be on the advisory “Brain Trust” for a project by Pulitzer-Prize-winning journalist, New Yorker writer, and Scientific American neuroscience blog editor Gareth Cook, who has set out to highlight the very best infographics produced each year, online and off. (Disclaimer for the naturally cynical: No money changed hands.) The Best American Infographics 2013 (public library) is now out, featuring the finest examples from the past year — spanning everything from happiness to sports to space to gender politics, and including a contribution by friend-of-Brain Pickings Wendy MacNaughton — with an introduction by none other than David Byrne. Accompanying each image is an artist statement that explores the data, the choice of visual representation, and why it works.

Byrne, who knows a thing or two about creativity and has himself produced some delightfully existential infographics, writes:

The very best [infographics] engender and facilitate an insight by visual means — allow us to grasp some relationship quickly and easily that otherwise would take many pages and illustrations and tables to convey. Insight seems to happen most often when data sets are crossed in the design of the piece — when we can quickly see the effects on something over time, for example, or view how factors like income, race, geography, or diet might affect other data. When that happens, there’s an instant “Aha!”…

Byrne addresses the healthy skepticism many of us harbor towards the universal potency of infographics, reminding us that the medium is not the message — the message is the message:

A good infographic … is — again — elegant, efficient, and accurate. But do they matter? Are infographics just things to liven up a dull page of type or the front page of USA Today? Well, yes, they do matter. We know that charts and figures can be used to support almost any argument. . . . Bad infographics are deadly!

One would hope that we could educate ourselves to be able to spot the evil infographics that are being used to manipulate us, or that are being used to hide important patterns and information. Ideally, an educated consumer of infographics might develop some sort of infographic bullshit detector that would beep when told how the trickle-down economic effect justifies fracking, for example. It’s not easy, as one can be seduced relatively easily by colors, diagrams and funny writing.

And, indeed, at the heart of the aspiration to cultivate a kind of visual literacy so critical for modern communication. Here are a few favorite pieces from the book that embody that ideal of intelligent elegance and beautiful revelation of truth:

America's Most Popular Birthdays

The days of the year, ranked by the number of babies born on each day in the United States (Matt Stiles, NPR data journalist)

Byrne — who believes the best use of infographics allows us to “experience a kind of geeky rapture as our senses are amplified and expanded through charts and illustrations” — is especially fond of one sub-genre:

Flowcharts [are] a form of poetry. And poetry is its own reward.

Indeed, flowcharts have a singular way of living at the intersection of the pragmatic and the existential:

Email: Help for Addicts

A handy flowchart to help you decide if you should check your email. (Wendy MacNaughton, independent illustrator, for Forbes)

How to Be Happy

Just ask yourself one question. (Gustavo Vieira Dias, creative director of DDB Tribal Vienna)

Some are visually elaborate:

The Breaking Bad Body Count

All of the deaths in the first fifty-four episodes of AMC's ‘Breaking Bad,’ with each deceased character represented by a faux chemical formula indicating when he or she died, how they died, and who killed them. (John D. LaRue)

The Four Kinds of Dog

Analyzing the DNA of 85 dog breeds, scientists found that genetic similarities clustered them into four broad categories. The groupings reveal how breeders have recombined ancestral stock to create new breeds; a few still carry many wolflike genes. Researchers named the groups for a distinguishing trait in the breeds dominating the clusters, though not every dog necessarily shows that trait. The length of the colored bars in a breed’s genetic profile shows how much of the dog’s DNA falls into each category. (John Tomanio, senior graphics editor, National Geographic)

Others appear more visually abstract yet derive from precise and concrete data sets:

Paths through New York City

‘Flow map’ of travel in New York City derived from the locations of tweets tagged with the locations of their senders. The starting and ending points of each trip come from a pair of geotagged tweets by the same person, and the path in between is an estimate, routed along the densest corridor of other people's geotagged tweets. (Eric Fischer, artist in residence at the Exploratorium in San Francisco)

Planets Everywhere

All of the planets discovered outside the Solar System. (Jan Willem Tulp, freelance information designer, for Scientific American)

Then there’s the mandatory love of pie charts and its derivatives:

Ten Artists, Ten Years

A revolution in color over ten extraordinary years in art history. Each pie chart represents an individual painting, with the five most prominent colors shown proportionally. (Arthur Buxton)

Seasonal Produce Calendars

The availability of produce in the northern hemisphere by month and season. (Russell van Kraayenburg)

The greatest power of infographics, however, lies in two things: Their ability to weave visual metaphors that enhance our understanding, something particularly potent given how essential metaphorical thinking is to the way we communicate and learn, and their role in igniting the very pattern recognition that fuels our creative comprehension. Byrne writes:

We have an inbuilt ability to manipulate visual metaphors in ways we cannot do with the things and concepts they stand for — to use them as malleable, conceptual Tetris blocks or modeling clay that we can more easily squeeze, stack, and reorder. And then — whammo! — a pattern emerges, and we’ve arrived someplace we would never have gotten by any other means.

Complement The Best American Infographics 2013 with Nathan Yau’s indispensable guide to telling stories with data and Taschen’s scrumptious showcase of the best information graphics from around the world.

The Shape of Spectacular Speech: An Infographic Analysis of What Made MLK’s “I Have a Dream” Great

By:

The poetics of presenting, or why beautiful metaphors are better than beautiful slides.

On August 28, 1963, Martin Luther King, Jr. rose to the top of the steps of the Lincoln Memorial during the March on Washington for Jobs and Freedom and delivered his legendary “I Have a Dream” speech before 250,000 civil rights supporters. It would go on to reverberate through the nation, reaching millions more, and through history, inspiring generations and forever changing the course of culture. But how can sixteen minutes of human speech have the power to move millions and steer history?

That’s exactly what presentation design guru Nancy Duarte, author of Resonate: Present Visual Stories that Transform Audiences (public library), probes as she analyzes the shape of Dr. King’s speech and what made it so monumentally impactful — a modern-day, infographic-powered version of Kurt Vonnegut’s iconic lecture on the shapes of stories exploring oration rather than narrative.

Duarte notes the Dr. King spoke in short bursts more reminiscent of poetry than of long-winded lecture-speak and highlights his most powerful rhetorical devices — repetition, metaphors, visual words, references to political documents, citations from sacred texts and spiritual songs — in a fascinating visualization of the speech, demonstrating how it embodies the core principles of her book.

Duarte followed up Resonate with Harvard Business Review’s HBR Guide to Persuasive Presentations, offering more specific strategies for honing the power of presentation, where she places special emphasis on the far-reaching power of metaphor and writes:

Metaphors are a powerful literary device. In Dr. Martin Luther King Jr.’s “I Have a Dream” speech, about 20% of what he said was metaphorical. For example, he likened his lack of freedom to a bad check that America has given the Negro people … a check that has come back marked ‘insufficient funds.’” King introduced his metaphor three minutes into his 16-minute talk, and it was the first time the audience roared and clapped.

Pair with five things every presenter should know about people and some timeless advice on how to give a great presentation.
