“When the graphs were finished, the relations were obvious at once”*…

We can only understand what we can “see”…

… this long-forgotten, hand-drawn infographic from the 1840s… known as a “life table,” was created by William Farr, a doctor and statistician who, for most of the Victorian era, oversaw the collection of public health statistics in England and Wales… it’s a triptych documenting the death rates by age in three key population groups: metropolitan London, industrial Liverpool, and rural Surrey.

With these visualizations, Farr was making a definitive contribution to an urgent debate from the period: were these new industrial cities causing people to die at a higher rate? In some ways, with hindsight, you can think of this as one of the most crucial questions for the entire world at that moment. The Victorians didn’t realize it at the time, but the globe was about to go from less than five percent of its population living in cities to more than fifty percent in just about a century and a half. If these new cities were going to be killing machines, we probably needed to figure that out.

It’s hard to imagine just how confusing it was to live through the transition to industrial urbanism as it was happening for the first time. Nobody really had a full handle on the magnitude of the shift and its vast unintended consequences. This was particularly true of public health. There was an intuitive feeling that people were dying at higher rates than they had in the countryside, but it was very hard even for the experts to determine the magnitude of the threat. Everyone was living under the spell of anecdote and availability bias. Seeing the situation from the birds-eye view of public health data was almost impossible…

The images Farr created told a terrifying and unequivocal story: density kills. In Surrey, the increase of mortality after birth is a gentle slope upward, a dune rising out of the waterline. The spike in Liverpool, by comparison, looks more like the cliffs of Dover. That steep ascent condensed thousands of individual tragedies into one vivid and scandalous image: in industrial Liverpool, more than half of all children born were dead before their fifteenth birthday.

The mean age of death was just as shocking: the countryfolk were enjoying life expectancies close to fifty, likely making them some of the longest-lived people on the planet in 1840. The national average was forty-one. London was thirty-five. But Liverpool—a city that had undergone staggering explosions in population density, thanks to industrialization—was the true shocker. The average Liverpudlian died at the age of twenty-five, one of the lowest life expectancies ever recorded in that large a human population.

There’s a natural inclination to think about innovation in human health as a procession of material objects: vaccines, antibiotics, pacemakers. But Farr’s life tables are a reminder that new ways of perceiving the problems we face, new ways of seeing the underlying data, are the foundations on which we build those other, more tangible interventions. Today cities reliably see life expectancies higher than rural areas—a development that would have seemed miraculous to William Farr, tabulating the data in the early 1840s. In a real sense, Farr laid the groundwork for that historic reversal: you couldn’t start to tackle the problem of how to make industrial cities safer until you had first determined that the threat was real.

Why the most important health innovations sometimes come from new ways of seeing: “The Obscure Hand-Drawn Infographic That Changed The Way We Think About Cities,” from Steven Johnson (@stevenbjohnson). More in his book, Extra Life, and in episode 3 of the PBS series based on it.

As we investigate infographics, we might send carefully calculated birthday greetings to Lewis Fry Richardson; he was born on this date in 1881.  A mathematician, physicist, and psychologist, he is best remembered for pioneering the modern mathematical techniques of weather forecasting.  Richardson’s interest in weather led him to propose a scheme for forecasting using differential equations, the method used today, though when he published Weather Prediction by Numerical Process in 1922, suitably fast computing was unavailable.  Indeed, his proof-of-concept– a retrospective “forecast” of the weather on May 20, 1910– took three months to complete by hand. (in fairness, Richardson did the analysis in his free time while serving as an ambulance driver in World War I.)  With the advent of modern computing in the 1950’s, his ideas took hold.  Still the ENIAC (the first real modern computer) took 24 hours to compute a daily forecast.  But as computing got speedier, forecasting became more practical.

Richardson also yoked his forecasting techniques to his pacifist principles, developing a method of “predicting” war.  He is considered (with folks like Quincy Wright and Kenneth Boulding) a father of the scientific analysis of conflict.

And Richardson helped lay the foundations for other fields and innovations:  his work on coastlines and borders was influential on Mandelbrot’s development of fractal geometry; and his method for the detection of icebergs anticipated the development of sonar.

“But when I make a good [taxidermy] mount I feel like I beat God in a small way. As though the Almighty said, Let such critter be dead, and I said, ‘F**k You, he can still play the banjo”*…

 

Afke and Floris met as students at Rietveld Academie. They began collaborating under the name This Work Must Be Designed by Idiots, incorporating dead animals in their work for shock value. Here, a peacock’s plumage turns into a beautiful garment.

This isn’t your gun-toting great-uncle’s taxidermy: there are no hunting trophies mounted on smoking den walls or Teddy Roosevelt-inspired museum dioramas. In Taxidermy Art: A Rogue’s Guide to the Work, the Culture, and How to Do It Yourself, Robert Marbury introduces a world of bionic crocodiles, pigs in Chanel bowties, impalas with human faces, and polar bears climbing on refrigerators (get it?).

In 2004, with two friends, Marbury established the Minnesota Association of Rogue Taxidermists (MART). In the decade since, Rogue Taxidermy–a genre of pop-surrealism that fuses traditional taxidermy with mixed-media sculpture–has evolved into a veritable subculture of people obsessed with turning dead animals into art. “Not since the Victorian era has taxidermy been so popular,” Marbury writes in the book’s introduction. (The Victorian era saw a trend of taxidermists like Walter Potter [see also here] making anthropomorphic tableaux of squirrels smoking cigars and kittens having tea parties.)…
