The Unpublished Manuscripts of 7 Famous Authors

Not every work by a great author ends up topping bestseller lists. Some never make it onto the shelves to begin with, because they've either been stolen, destroyed, or locked inside a literary time capsule. Here are some unpublished manuscripts that never reached the same level of fame as the authors who wrote them.

1. THE ISLE OF THE CROSS // HERMAN MELVILLE

Following the commercial failures of Moby Dick and Pierre; or, The Ambiguities, Herman Melville was due for a stroke of luck. Unfortunately, his next novel, The Isle of the Cross, didn’t deliver it. The book reportedly drew from a true story Melville had heard on a trip to Nantucket about Agatha Hatch, the daughter of a Massachusetts lighthouse keeper who married a sailor only to be abandoned by him while she was pregnant—and have him return 17 years later. Melville encouraged his literary friend Nathaniel Hawthorne to turn the tale into a novel, but he turned down the offer, prompting Melville to write it himself. Harper’s, his publisher, rejected the work, though the motive remains unclear. Some have suggested that the publishers wanted to avoid any potential legal blowback from relatives of Hatch who may have recognized themselves in the work. Any copies of the manuscript have been lost to time.

2. OUR MARRIED LIFE, JOHNSON, THE MYSTERY OF BONITA, AND MOLLY OODLE // L. FRANK BAUM

The fiction of L. Frank Baum wasn’t confined to the wonderful world of Oz. He penned several books aimed at mature audiences during his lifetime. If you're unfamiliar with this section of his work, there’s a good reason: Four of his adult novels—Our Married Life (1912), Johnson (1912), The Mystery of Bonita (1914), and Molly Oodle (1915)—were never published. Baum’s oldest son Frank alleged in his memoir that his mother had set the manuscripts on fire, though many suspect he lied about this to get back at her for bumping him from her will.

3. DOUBLE EXPOSURE (OR DOUBLETAKE) // SYLVIA PLATH

Sylvia Plath died of suicide at the early age of 30, leaving the world with her first and only novel, The Bell Jar. At least, that’s how it appeared until her widower Ted Hughes (also a writer) revealed in his 1977 memoir that Plath had been working on a second book. In the year leading up to her death, Plath was writing an autobiographical novel titled Double Exposure or Doubletake. Supposedly, the book dealt with the disintegration of Plath’s marriage to Hughes. Hughes gives a cursory mention of the piece in his book, writing that Plath had “typed some 130 pages of another novel” (he later changed the number to 60 or 70 pages), and that the manuscript “disappeared somewhere around 1970.” The exact fate of the novel, or even whether or not it was completed, is still unknown. Given that it likely painted an unflattering picture of the adulterous Hughes, there are those who suspect the “disappearance” wasn’t a complete accident.

4. THE POOR MAN AND THE LADY // THOMAS HARDY

In 1868-69, Thomas Hardy submitted his first novel to a couple London publishing houses. While the publishers apparently expressed interest, their reader George Meredith suggested it be withdrawn it from consideration for fear that it would hurt Hardy’s young career. Meredith allegedly went so far as to meet with Hardy to deliver his advice in person—though according to the 1921 biography Thomas Hardy, Poet & Novelist, it’s also possible that the book was rejected right off the bat.

Hardy recalled years later that Meredith had derided the book for being overly philosophical and satirical. Though he held on to the manuscript throughout his career as a successful poet and novelist, he ultimately destroyed it years before his death.

5. UNFINISHED WORLD WAR I NOVEL // ERNEST HEMINGWAY

The theft of a suitcase filled with early Hemingway work was one of the most infamous events in the history of literature. The crime occurred after Hadley, Ernest’s first wife, brought all of her husband’s writings from their Paris home to Switzerland—where he was covering the Lausanne Peace Conference—to show fellow author Lincoln Steffens. But the package never reached its destination; the bag of papers was stolen from Hadley’s seat on the train before she arrived. The lost work included the carbon copies and originals of all his short stories, as well as an in-progress World War I novel. Hemingway never attempted a rewrite of those works; he went on to author The Sun Also Rises instead.

6. PRINCE JELLYFISH // HUNTER S. THOMPSON

Before Hunter S. Thompson pioneered his Gonzo style of journalism, he attempted to launch a career as a novelist. His first book, Prince Jellyfish, was an autobiographical tale that followed a boy from Louisville trying to make it in the big city. The manuscript was rejected by publishers, and Thompson later admitted that it had been forgettable. His next fiction project was The Rum Diaries, a story inspired by his time as a journalist living in Puerto Rico. That book also went unpublished until his friend Johnny Depp rediscovered it at his home in 1998. The actor was the one who encouraged Thompson to finally get the book in print.

7. SCRIBBLER MOON // MARGARET ATWOOD

Unlike many works on this list, Margaret Atwood’s Scribbler Moon isn’t lost. The story is safe inside a special room at the Deichmanske Public Library in Norway, but it won’t be read until 2114.

Atwood’s manuscript marked the first entry into the Future Library. Conceived by Scottish artist Katie Paterson, the literary time capsule will gain one original piece from a prominent author every year for the next 100 years. As the century trickles down, a forest of saplings planted outside Oslo in 2014 will flourish. When the contents of the library are ready to be seen, the trees will be chopped down and made into paper for the stories to be printed on. Most of Atwood’s present-day fans likely won’t be around to read her contribution, but if you’re feeling optimistic about your chances of living well into the next century, or if you want to do something nice for your offspring, you can reserve a copy of the Future Library collection in its entirety for $1000.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning
Original image
iStock // Ekaterina Minaeva

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!
