12 Facts About Frank Lloyd Wright's Fallingwater

Tucked away in the sleepy forests of southwestern Pennsylvania sits one of the world’s most famous buildings: Frank Lloyd Wright’s Fallingwater. Commissioned by wealthy department store owner Edgar J. Kaufmann and completed in 1937, the home’s cantilevered tiers hang suspended atop a 30-foot waterfall—Wright’s ingenious way of melding the man-made structure with its natural surroundings [PDF]. Here are 12 facts about the work’s history and legacy.

1. FALLINGWATER HELPED FRANK LLOYD WRIGHT MAKE A COMEBACK.

Today, Frank Lloyd Wright (1867-1959) is revered as one of history’s greatest architects—but by the time he reached his late 60s, many critics considered him to be washed up. Wright had only built a few buildings in the previous decade, the Great Depression had diminished demand for new projects, and, adding insult to injury, his younger peers considered his style to be anachronistic. Kaufmann—whose department store, Kaufmann’s, was later incorporated into Macy’s—helped resuscitate Wright's career when he asked the architect to design a weekend home in the Laurel Highlands for his family.

Nobody quite knows how the Kaufmann family and Wright first became acquainted. However, we do know that Kaufmann’s son, Edgar Kaufmann Jr., admired the architect's work, and studied under Wright as an apprentice at his Taliesin Studio in Wisconsin. In 1934, the young student's parents visited Taliesin and met Wright in person. Shortly after, the Kaufmanns asked Wright to build Fallingwater.

With Fallingwater, Wright proved to the world that he wasn't quite finished yet, ushering in a final, fruitful period of his career. Near the end of his life, Wright designed a handful of other renowned works, including the Monona Terrace Civic Center in Madison, Wisconsin and the Guggenheim Museum in New York City.

2. FALLINGWATER’S CONSTRUCTION SITE WAS ORIGINALLY A “SUMMER CAMP” FOR KAUFMANN’S EMPLOYEES.

The site Kaufmann chose for his home was a swath of wilderness near the villages of Mill Run and Ohiopyle, on a mountain stream called Bear Run. Once upon a time, the wooded area had been home to a small cabin where Kaufmann’s employees sought refuge from Pittsburgh’s pollution. But once the Great Depression struck, the employees could no longer afford to travel there, so Kaufmann decided to convert it into a country getaway.

3. WRIGHT IS RUMORED TO HAVE SKETCHED FALLINGWATER’S DESIGN IN ONLY TWO HOURS.

According to legend, Wright sketched Fallingwater in only two hours. In 1934, the architect visited the home's construction site and asked for an area survey. Then, he did absolutely nothing for nearly a year—until Kaufmann traveled to Milwaukee and called up Wright, announcing he’d be paying a surprise visit to his Wisconsin studio, Taliesin, to view the plans. Wright and his apprentices reportedly drew Fallingwater in the time it took his wealthy patron to drive to Taliesin.

Needless to say, Franklin Toker, author of Fallingwater Rising: Frank Lloyd Wright, E. J. Kaufmann, and America's Most Extraordinary House, is skeptical of this claim. “We want to believe drawing up Fallingwater needed only two hours, just as we want to believe—despite massive contrary evidence—that Lincoln scribbled the Gettysburg Address on the back of an envelope,” he writes. “We don’t want to hear that Lincoln struggled through five drafts on his historic oration because that makes the speech less of a work of genius.” And in this case, one of Wright’s associates remembered Wright and Kaufmann discussing that the house would be built on the falls months before the supposed rush of inspiration.

4. THE KAUFMANNS DIDN’T KNOW THAT THEIR HOME WOULD BE BUILT ATOP A WATERFALL.

According to another legend (many of Wright’s apprentices disagree on key details of how Fallingwater was conceived, so learning the truth is difficult), Kaufmann thought that Wright would design the home on the banks of the river, facing the waterfall, so he was surprised when he looked at Wright’s plans and saw that his country estate would sit on top of it. Wright explained that he wanted to integrate the house with the waterfall so it would be an essential part of the structure instead of simply serving as a pretty backdrop. (You can’t actually see the waterfall from Fallingwater, but visitors can hear rushing water if they listen closely.)

5. FALLINGWATER'S INTERIOR IS DESIGNED TO RESEMBLE NATURE ...

Wright wanted Fallingwater’s interior to feel like the surrounding forest. The 5300-square foot home’s walls and floors are constructed of local sandstone; a rock outcropping is incorporated into the living room's hearth; each bedroom has its own terrace; and its cornerless windows open outward so windowpanes won’t interrupt visitors' view. There’s even a glass hatchway in the main level's floor that opens to reveal a staircase leading down to the stream below.

6. ... BUT ITS OUTSIDE WAS ORIGINALLY SUPPOSED TO BE COVERED IN GOLD LEAF.

Wright opted for a rustic, natural look when he designed Fallingwater. Only two colors of paint were applied to the concrete, sandstone, glass, and steel structure—light ochre for the concrete, and Cherokee red for the steel. However, Wright originally envisioned a more flamboyant aesthetic: He proposed that the home’s concrete exterior be coated in gold leaf.

The Kaufmanns thought that gold leaf would be too over-the-top for a country house, and after rejecting Wright’s secondary proposal (a white mica finish), they settled on the ochre, which, according to Wright, was inspired by “the sere leaves of the rhododendron.”

7. FALLINGWATER STILL HAS ALL ITS ORIGINAL FURNISHINGS AND ARTWORK.

Wright didn’t just design Fallingwater—he also custom-designed its furniture. Around half of the furnishings were built into the house, which Wright said made them “client-proof” (i.e., unable to be removed and replaced with tackier/incongruous purchases). Today, Fallingwater is the only remaining home designed by Wright that still has its original furnishings and artwork.

8. FALLINGWATER HAS STRUCTURAL PROBLEMS.

Fallingwater is an architectural marvel, but it still has a few major flaws. Its skylights leak, the waterfall promotes mold growth (Kaufmann nicknamed Fallingwater “Rising Mildew”), and—even worse—the builders didn’t use enough reinforcing steel to support the first floor’s concrete skeleton.

Kaufmann had initial doubts about the technical feasibility of Wright's concept, and he hired consulting engineers to examine Wright's plans. They discovered that the main floor's girders needed additional reinforcement, but Wright dismissed this claim and forged ahead with construction.

Over time, gravity caused the home's first floor cantilever to sag, and in 2002, the structure’s foundation was reinforced to prevent a future collapse. In the process, the first level’s stone floor and furniture had to be ripped out.

9. FALLINGWATER WOULD BE WORTH MILLIONS OF DOLLARS TODAY.

Kaufmann's original budget for Fallingwater was somewhere between $20,000 and $30,000, but in the end, it and a guesthouse ended up costing the family $155,000. (This sum included $8000 worth of architect fees and $4500 for installed walnut furnishings.) That amount now translates to over $2.5 million after calculating for inflation.

10. FALLINGWATER RECEIVES THOUSANDS OF VISITORS PER YEAR.

Fallingwater remained in the Kaufmann family’s possession from 1937 to 1963. Edgar Kaufmann Jr. inherited the home after his father's death in 1955, and he later donated the home and its surrounding 1750 acres of land to a nonprofit trust called the Western Pennsylvania Conservancy. Nearly 5 million people have visited Fallingwater since 1964, and the home received more than 167,000 visitors in 2015 alone.

11. AYN RAND'S THE FOUNTAINHEAD WAS PARTLY INSPIRED BY WRIGHT AND FALLINGWATER.

Both Frank Lloyd Wright and Fallingwater are believed to have inspired writer Ayn Rand’s seminal 1943 novel The Fountainhead. Its protagonist, the iconoclastic architect Howard Roark, bears a striking resemblance to Wright, and several of the homes Roark designs for clients resemble Fallingwater. Toker even goes so far as to guess that the book’s title—which Rand changed from Second-Hand Lives to The Fountainhead—pays homage to Fallingwater, as both monikers are 12 letters long, begin with the letter “F,” and conjure the image of cascading water.

12. FALLINGWATER HASN’T MADE THE CUT FOR THE UNESCO WORLD HERITAGE LIST QUITE YET.

Fallingwater has received plenty of accolades and honors over the years. It was named a National Historic Landmark in 1966, and in 1991, an American Institute of Architects poll voted it as the "best all-time work of American architecture." However, the home has yet to be added to the United Nations’s World Heritage List of significant cultural landmarks.

The U.S. Department of the Interior nominated 10 of Wright’s buildings (including Fallingwater, the Guggenheim Museum in New York City, and more) for inclusion in 2015. But last summer, a UNESCO committee decided they needed to review additional information before making a final decision. Their requests included a revised argument for why Wright sites should be considered to be of “outstanding universal value,” along with clarified specifics of how the individual properties would be managed.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
May 21, 2017

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

8 Common Dog Behaviors, Decoded
May 25, 2017

Dogs are a lot more complicated than we give them credit for. As a result, sometimes things get lost in translation. We’ve yet to invent a dog-to-English translator, but there are certain behaviors you can learn to read in order to better understand what your dog is trying to tell you. The more tuned-in you are to your dog’s emotions, the better you’ll be able to respond—whether that means giving her some space or welcoming a wet, slobbery kiss. 

1. What you’ll see: Your dog is standing with his legs and body relaxed and tail low. His ears are up, but not pointed forward. His mouth is slightly open, he’s panting lightly, and his tongue is loose. His eyes? Soft or maybe slightly squinty from getting his smile on.

What it means: “Hey there, friend!” Your pup is in a calm, relaxed state. He’s open to mingling, which means you can feel comfortable letting friends say hi.

2. What you’ll see: Your dog is standing with her body leaning forward. Her ears are erect and angled forward—or have at least perked up if they’re floppy—and her mouth is closed. Her tail might be sticking out horizontally or sticking straight up and wagging slightly.

What it means: “Hark! Who goes there?!” Something caught your pup’s attention and now she’s on high alert, trying to discern whether or not the person, animal, or situation is a threat. She’ll likely stay on guard until she feels safe or becomes distracted.

3. What you’ll see: Your dog is standing, leaning slightly forward. His body and legs are tense, and his hackles—those hairs along his back and neck—are raised. His tail is stiff and twitching, not swooping playfully. His mouth is open, teeth are exposed, and he may be snarling, snapping, or barking excessively.

What it means: “Don’t mess with me!” This dog is asserting his social dominance and letting others know that he might attack if they don’t defer accordingly. A dog in this stance could be either offensively aggressive or defensively aggressive. If you encounter a dog in this state, play it safe and back away slowly without making eye contact.

4. What you’ll see: As another dog approaches, your dog lies down on his back with his tail tucked in between his legs. His paws are tucked in too, his ears are flat, and he isn’t making direct eye contact with the other dog standing over him.

What it means: “I come in peace!” Your pooch is displaying signs of submission to a more dominant dog, conveying total surrender to avoid physical confrontation. Other, less obvious, signs of submission include ears that are flattened back against the head, an avoidance of eye contact, a tongue flick, and bared teeth. Yup—a dog might bare his teeth while still being submissive, but they’ll likely be clenched together, the lips opened horizontally rather than curled up to show the front canines. A submissive dog will also slink backward or inward rather than forward, which would indicate more aggressive behavior.

5. What you’ll see: Your dog is crouching with her back hunched, tail tucked, and the corner of her mouth pulled back with lips slightly curled. Her shoulders, or hackles, are raised and her ears are flattened. She’s avoiding eye contact.

What it means: “I’m scared, but will fight you if I have to.” This dog’s fight or flight instincts have been activated. It’s best to keep your distance from a dog in this emotional state because she could attack if she feels cornered.

6. What you’ll see: You’re staring at your dog, holding eye contact. Your dog looks away from you, tentatively looks back, then looks away again. After some time, he licks his chops and yawns.

What it means: “I don’t know what’s going on and it’s weirding me out.” Your dog doesn’t know what to make of the situation, but rather than nipping or barking, he’ll stick to behaviors he knows are OK, like yawning, licking his chops, or shaking as if he’s wet. You’ll want to intervene by removing whatever it is causing him discomfort—such as an overly grabby child—and giving him some space to relax.

7. What you’ll see: Your dog has her front paws bent and lowered onto the ground with her rear in the air. Her body is relaxed, loose, and wiggly, and her tail is up and wagging from side to side. She might also let out a high-pitched or impatient bark.

What it means: “What’s the hold up? Let’s play!” This classic stance, known to dog trainers and behaviorists as “the play bow,” is a sign she’s ready to let the good times roll. Get ready for a round of fetch or tug of war, or for a good long outing at the dog park.

8. What you’ll see: You’ve just gotten home from work and your dog rushes over. He can’t stop wiggling his backside, and he may even lower himself into a giant stretch, like he’s doing yoga.

What it means: “OhmygoshImsohappytoseeyou I love you so much you’re my best friend foreverandeverandever!!!!” This one’s easy: Your pup is overjoyed his BFF is back. That big stretch is something dogs don’t pull out for just anyone; they save that for the people they truly love. Show him you feel the same way with a good belly rub and a handful of his favorite treats.

The best way to say “I love you” in dog? A monthly subscription to BarkBox. Your favorite pup will get a package filled with treats, toys, and other good stuff (and in return, you’ll probably get lots of sloppy kisses). Visit BarkBox to learn more.
