What Engels’ (Least) Favorite Color Teaches about Capitalism

"Any one not Aniline"

Did you ever receive one of those 90s chain emails in your inbox? You know, the kind where you fill in your favorite band/animal/team/color/etc. and then send it to ten friends or else you’d have bad luck for the week?

I recently stumbled across a 19th century version, a “confession” filled out by Friedrich Engels, the original champagne socialist who is now best known for popularizing Karl Marx’s ideas.

Frederick Engels "Confession"

Little on the list is truly surprising. Engels wouldn’t be the first notorious womanizer (and accused rapist) to declare his love for women even while evincing a base misogyny.

But the answer that immediately caught my eye was Engels’ favorite color: “Any one not Aniline.” Now, if you’re an ordinary, well-adjusted denizen of the 21st century, odds are that you immediately considered opening a new tab to ask Google, “What color is aniline?”

There’s no need to click away. Aniline was mauve. And it is hard to overstate the extent to which various shades of the new purple swept the world of fashion in the 1850s and 1860s.

That’s because aniline was the first commercially-scalable synthetic dye, invented at a time when chemists were unlocking the secrets of the universe by distilling, vaporizing, and generally futzing with every substance they could get their hands on.

Aniline was actually the product of a failed British attempt in 1856 to synthesize quinine in hopes of making anti-malarial treatments cheaper and easier to produce than the old way of grinding up the bark of a hard to acquire Amazonian tree. The result wouldn’t especially help imperialists expand their empires over mosquito-infested jungles, but it did produce a particularly vivid shade of purple.

The researcher, an eighteen year old college student named William Perkin, was also an amateur painter, and immediately saw the value of a cheap, easy to produce dye that was more durable than existing alternatives. Seeking capital investment, Perkin partnered with Robert Pullar, a Scottish dye entrepreneur who would later become a radical pro-free trade member of Parliament. By the end of the century, Perkin and Pullar owned a global network of synthetic dye factories that brought color to the masses.

This meant that purplish, pinkish, and reddish dyes were suddenly this cheap and widely available for the first time in human history. Tweaking the distillation process could produce mauveine, fuchsin, and safranin, which are the synthetic forerunners of the colors we call mauve, fuchsia/magenta, and saffron today. It may have been the single most significant moment in modern fashion history.

Prior to this, many of the dyes used for clothing and paint had to be ground up from natural ingredients. For instance, if you lived in 4th century Rome and wanted to wear purple clothing, you needed someone to find and grind up twelve thousand snails of a particular species that lived mostly in the Eastern Mediterranean Sea. Doing so would yield 1.4 grams of dye, which was barely enough to color the trim of a single piece of clothing. The cost of purple was thus astronomical; pound for pound, “Tyrian purple” was worth three times as much as pure gold! And purple dye was so hard to acquire, at any price, that sumptuary laws often prohibited anyone except royalty from wearing purple clothing.

But after 1856, the ability to synthesize aniline meant that purple hues were suddenly everywhere. What had once cost pounds of gold now cost mere pennies. Mauve was all the rage — people were contracting “mauve measles,” as British wags put it — a fact that would not have been lost on Engels’ when he wrote out his list in 1868 since his family fortune was tied up in textiles. (He properly capitalized “Aniline” since it was then still a proprietary product.)

When you see televised depictions of Victorian era fashion, like middle class women wearing acres of brightly-colored fabric, you are looking at a byproduct of the synthetic dyes revolution.

And that wave of color cascaded step-by-step, class-by-class, down throughout society. Cheaper, more durable, and more vivid products abounded, from housepaints to wallpapers. Today, we take for granted the idea that color is near costless. It would strike a 21st century consumer as bizarre if they were told that a bright purple dress or mauve house paint would cost 10x (or 1000x) the price of one that was white.

Even so, the rise of synthetic purple sparked a sartorial reaction. Purple, as long as it was rare and inaccessible to the plebeians, was considered dignified, elegant, and noble. But once purple became commonplace, it was gauche and uncouth. A century later when cultural critic Paul Fussell summarized the ways that dress signified class status, he lumped purple in with polyester fibers and sports jerseys as markers of belonging to the grubby “proles.”

And that brings us back to Engels’ sneering response, “Any one but Aniline.” On the one hand, it’s not surprising that a textile manufacturer might be annoyed at the disruption to his existing (and profitable) supply chain. Engels was also a product of inherited wealth, and making fun of Aniline was common sport for his class at the time. A satirical Punch cartoon of 1877 featured a dilettante sniveling about a debutante, “She affects Aniline dyes, don’t you know! I weally couldn’t go down to suppah with a young Lady who wears Mauve twimmings in her skirt, and magenta wibbons in her hair!”

Pecuniary self-interest and class snobbery aside, Engels wouldn’t be the first socialist guilty of reflexive suspicion towards technological innovation and the capitalists that had made it possible. The Luddites you will always have with you.

For whatever reason, Engels failed to see how the invention of synthetic dyes was a boon to workers and society as a whole, a future in which the rare colors of kings would become the ordinaries of proles. Capitalist incentives had once again commissioned a technological innovation that could push back against harsh, natural scarcity. Life would become a little bit brighter and bolder because of it.

Every one Aniline.

Foxconn Hires Humanoid Robots to Make Servers at Nvidia Factory

“Taiwanese contract manufacturer Foxconn has confirmed it will use humanoid robots to make Nvidia servers in America.

Foxconn CEO and chairman Young Liu yesterday told Japanese outlet Nikkei the company will deploy the bots ‘within six months or so’ and that they will help to speed production.

The company made a passing reference to the bots last week in a press release that said Foxconn is working with Nvidia ‘to build a next-generation smart manufacturing plant for AI servers’ that will be ‘among the first to deploy humanoid robots powered by the NVIDIA Isaac GR00T N model on its production lines.’

Liu didn’t say how many bots Foxconn will put to work, didn’t describe the machines and their capabilities, didn’t say what roles they will take on, or whether they would obviate the need for human workers. Nor did he explain why humanoid robots are a good fit for Nvidia’s factory, a significant issue as building robots that replicate human anatomy is generally considered wasteful unless they will work in environments built for people.”

DeepMind’s AI for Coordinating Manufacturing Robots

“A lot of the stuff we use today is largely made by robots—arms with multiple degrees of freedom positioned along conveyor belts that move in a spectacle of precisely synchronized motions. All this motion is usually programmed by hand, which can take hundreds to thousands of hours. Google’s DeepMind team has developed an AI system called RoboBallet that lets manufacturing robots figure out what to do on their own.”

Grim Old Days: Virginia Postrel’s Fabric of Civilization

Beneath today’s abundance of clothing lies a long and brutal history.

Summary: Virginia Postrel’s book weaves a sweeping history of textiles as both drivers of innovation and toil. From ancient women spinning for months to make a single garment to brutal sumptuary laws and dye trades steeped in labor and odor, it is revealed how fabric shaped the foundations of human society.


Virginia Postrel’s The Fabric of Civilization: How Textiles Made the World is the riveting story of how humanity’s quest for thread, cloth, and clothing built modern civilization, by motivating achievements from the Neolithic Revolution to the Industrial Revolution and more. While much of the book contains inspiring tales of innovation, artistry, and entrepreneurship, the parts of the book about the preindustrial era also reveal some dark and disturbing facts about the past.

In the preindustrial era, clothing was often painstakingly produced at home. Postrel estimates that, in Roman times, it took a woman about 909 hours—or 114 days, almost 4 months—to spin enough wool into yarn for a single toga. With the later invention of the spinning wheel, the time needed to produce yarn for a similarly sized garment dropped to around 440 hours, or 50 days. Even in the 18th century, on the eve of industrialization, Yorkshire wool spinners using the most advanced treadle spinning wheels of the time would have needed 14 days to produce enough yarn for a single pair of trousers. Today, by contrast, spinning is almost entirely automated, with a single worker overseeing machines that are able to produce 75,000 pounds of yarn a year—enough to knit 18 million T-shirts.

Most preindustrial women devoted enormous amounts of time to producing thread, which they learned how to make during childhood. It is not an exaggeration to say, as Postrel does, “Most preindustrial women spent their lives spinning.” This was true across much of the world. Consider Mesoamerica:

At only four years old, an Aztec girl was introduced to spinning tools. By age six, she was making her first yarn. If she slacked off or spun poorly, her mother punished her by pricking her wrists with thorns, beating her with a stick, or forcing her to inhale chili smoke.

These girls often multitasked while spinning: “preindustrial spinners could work while minding children or tending flocks, gossiping or shopping, or waiting for a pot to boil.” The near-constant nature of the task meant that prior to the Industrial Revolution, “industry’s visual representation was a woman spinning thread: diligent, productive, and absolutely essential” to the functioning of society, and from antiquity onward cloth-making was viewed as a key feminine virtue. Ancient Greek pottery portrays spinning “as both the signature activity of the good housewife and something prostitutes do between clients,” showing that women of different social classes were bound to spend much of their lives engaged in this task.

Women of every background worked day and night, but still, their efforts were never enough. “Throughout most of human history, producing enough yarn to make cloth was so time-consuming that this essential raw material was always in short supply.”

Having sufficient spun yarn or thread was only the beginning; it still had to be transformed into cloth. “It took three days of steady work to weave a single bolt of silk, about thirteen yards long, enough to outfit two women in blouses and trousers,” although silk-weavers themselves could rarely afford to wear silk. According to Postrel, a Chinese poem from the year 1145, paired with a painting of a modestly dressed, barefoot peasant weaving silk, suggests that “the couple in damask silk . . . should think of the one who wears coarse hemp.”

Subdued colors often defined the clothing of the masses. “‘Any weed can be a dye,’ fifteenth-century Florentine dyers used to say. But that’s only if you want yellows, browns, or grays—the colors yielded by the flavonoids and tannins common in shrubs and trees.” Other dye colors were harder to produce.

In antiquity, Tyrian purple was a dye derived from crushed sea snails, and the notoriously laborious and foul-smelling production process made it expensive. As a result, it became a status symbol, despite the repulsive stench that clung to the fabric it colored. In fact, according to Postrel, the poet Martial included “a fleece twice drenched in Tyrian dye” in a list of offensive odors, with a joke that a wealthy woman wore the reeking color to conceal her own body odor. The fetor became a status symbol. “Even the purple’s notorious stench conveyed prestige, because it proved the shade was the real thing, not an imitation fashioned from cheaper plant dyes.” The color itself was not purple, despite the name, but a dark hue similar to the color of dried blood. Later, during the Renaissance, Italian dyers yielded a bright red from crushed cochineal insects imported from the Americas, as well as other colors that were created by using acidic bran water that was said to smell “like vomit.”

Numerous laws strictly regulated what people were allowed to wear. Italian city-states issued more than 300 sumptuary laws between 1300 and 1500, motivated in part by revenue-hungry governments’ appetite for fines. For example, in the early 1320s, Florence forbade women from owning more than four outfits that were considered presentable enough to wear outside. Postrel quotes the Florentine sumptuary law official Franco Sacchetti as writing that women often ignored the rules and argued with officials until the latter gave up on enforcement; he ends his exasperated account with the saying, “What woman wants the Lord wants, and what the Lord wants comes to pass.” But enough fines were collected to motivate officials to enact ever more restrictions.

In Ming Dynasty China, punishment for dressing above one’s station could include corporal punishment or penal servitude. Yet, as in Florence, and seemingly nearly everywhere that sumptuary laws were imposed, such regulations were routinely flouted, with violators willing to risk punishment or fines. In France in 1726, the authorities harshened the penalty for trafficking certain restricted cotton fabrics, which were made illegal in 1686, to include the death penalty. The French law was not a traditional sumptuary law, but an economic protectionist measure intended to insulate the domestic cloth industry from foreign competition. Postrel quotes the French economist André Morellet lamenting the barbarity of this rule, writing in 1758,

Is it not strange that an otherwise respectable order of citizens solicits terrible punishments such as death and the galleys against Frenchmen, and does so for reasons of commercial interest? Will our descendants be able to believe that our nation was truly as enlightened and civilized as we now like to say when they read that in the middle of the eighteenth century a man in France was hanged for buying [banned cloth] to sell in Grenoble for 58 [coins]?

Despite such disproportionate punishments, the textile-smuggling trade continued.

Postrel’s book exposes the brutal realities woven into the history of textiles; stories not just of uplifting innovation, but of relentless toil, repression, and suffering. Her book fosters a deeper appreciation for the wide range of fabrics and clothes that we now take for granted, and it underscores the human resilience that made such abundance and choice possible.

InventWood to Produce Wood That’s Stronger than Steel

“It sounds like the stuff of science fiction, but it actually comes from a lab in Maryland.

In 2018, Liangbing Hu, a materials scientist at the University of Maryland, devised a way to turn ordinary wood into a material stronger than steel. It seemed like yet another headline-grabbing discovery that wouldn’t make it out of the lab.

‘All these people came to him,’ said Alex Lau, CEO of InventWood, ‘He’s like, OK, this is amazing, but I’m a university professor. I don’t know quite what to do about it.’

Rather than give up, Hu spent the next few years refining the technology, reducing the time it took to make the material from more than a week to a few hours. Soon, it was ready to commercialize, and he licensed the technology to InventWood.

Now, the startup’s first batches of Superwood will be produced starting this summer.”
