The Quick 10: 10 Celebs Who Worked at Disney

Original image

We're just a few days from our annual Halloween pilgrimage to Disneyworld and I'm getting a little antsy. I'm not sure if writing about Disney is helping time go by more quickly or grinding it to a halt, but either way, this was a fun topic to research. These days we think of "celebrities who started at Disney" as those mini-starlets on the Disney Channel: Miley, Selena, Demi and all of their protégés just waiting in the wings. But these celebrities were actually out there in the trenches, working in parades and telling corny jokes.

martin1. Steve Martin started his career as a magician at the Main Street Magic Shop at Disneyland. After spending a lot of time at the shop during his youth, he took a job there and mastered magic, juggling, banjo-playing and creating balloon animals. Steve showed that he's still got what it takes "“ he showed off a couple of his old sleight-of-hand tricks for an anniversary video that played in the park.
2. Teri Garr. Martin's co-star Teri Garr also spent some time working at the Happiest Place on Earth. I see her as Cinderella, myself, or perhaps Alice in Wonderland, but Teri was actually a non-character parade dancer.

3. John McEuen, a founding member of the Nitty Gritty Dirt Band. John actually worked with Steve Martin at the magic shop and is the one who taught him how to play the banjo. They went to high school together and remained friends even after they both got famous "“ it's the Nitty Gritty Dirt Band who backed Martin on "King Tut."

4. Michelle Pfeiffer. I guess Teri Garr couldn't have been Alice, because Michelle Pfeiffer had already claimed the position. Michelle was Alice in the Main Street Electrical Parade in the mid-70s.

5. Alyson Reed is another Alice. You might not know the name, but if you have kids of a certain age I bet you know the face "“ despite being an accomplished Broadway actress, she may be best known today for her role as Ms. Darbus in High School Musical.

6. John Lasseter, as in the chief creative officer at PIXAR and Disney Animation Studios, started his relationship with The Mouse long before Toy Story: upon his graduation, he got a job at Disneyland as a Jungle Cruise Skipper and later moved up to animator.

7. Ron Ziegler, Richard Nixon's press secretary. OK, none of these have probably really stunned you up until this point "“ they're all creative types. But Ron Ziegler? Yup. He was also a skipper on the Jungle Cruise while attending USC.

bluefairy8. Joanna Kerns, best known as the mom from Growing Pains. Back in the day of the Main Street Electrical Parade, Joanna played the Blue Fairy (although that's not her pictured) from Pinocchio whose float kicked off the festivities. Picture by Deb Willis of AllEarsNet.
9. Richard Carpenter of The Carpenters. His story is kind of fun. He worked as one half of a banjo and piano duo, playing old ragtime pieces to fit in with the Main Street theme. At least, they were supposed to. They often took requests from park patrons to play more contemporary songs, like "Light My Fire." Their boss, Vic Guder, fired them after multiple offenses. Carpenter's response, the anti-establishment song "Mr. Guder," can be found on The Carpenters' LP Close to You.

10. Ronald Reagan, kind of. He was just an out-of-work actor the day Disneyland opened in 1955, and Disney hired him to host a live telecast of the park's opening. He may not have been a regular cast member, but Disney included him when they recognized all first-day cast members by giving them a lifetime membership to the exclusive Club 55 (not to be confused with Club 33, which anyone can eventually join if they have enough money).

And an honorable mention: Jen at Cake Wrecks was a skipper on the Jungle Cruise as well. The awesomely bad puns on Cake Wrecks totally make sense now!

Do you know any celebrities who sold Mickey ice cream bars or toiled all day under a hot costume? If I've left anyone out, share in the comments! And if you're interested in Disney tweets, I'll probably be chronicling my week in 140 characters or less next week.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

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!

New Evidence Emerges in Norway’s Most Famous Unsolved Murder Case
May 22, 2017

A 2016 sketch by a forensic artist of the Isdal Woman
Stephen Missal

For almost 50 years, Norwegian investigators have been baffled by the case of the “Isdal Woman,” whose burned corpse was found in a valley outside the city of Bergen in 1970. Most of her face and hair had been burned off and the labels in her clothes had been removed. The police investigation eventually led to a pair of suitcases stuffed with wigs and the discovery that the woman had stayed at numerous hotels around Norway under different aliases. Still, the police eventually ruled it a suicide.

Almost five decades later, the Norwegian public broadcaster NRK has launched a new investigation into the case, working with police to help track down her identity. And it is already yielding results. The BBC reports that forensic analysis of the woman’s teeth show that she was from a region along the French-German border.

In 1970, hikers discovered the Isdal Woman’s body, burned and lying on a remote slope surrounded by an umbrella, melted plastic bottles, what may have been a passport cover, and more. Her clothes and possessions were scraped clean of any kind of identifying marks or labels. Later, the police found that she left two suitcases at the Bergen train station, containing sunglasses with her fingerprints on the lenses, a hairbrush, a prescription bottle of eczema cream, several wigs, and glasses with clear lenses. Again, all labels and other identifying marks had been removed, even from the prescription cream. A notepad found inside was filled with handwritten letters that looked like a code. A shopping bag led police to a shoe store, where, finally, an employee remembered selling rubber boots just like the ones found on the woman’s body.

Eventually, the police discovered that she had stayed in different hotels all over the country under different names, which would have required passports under several different aliases. This strongly suggests that she was a spy. Though she was both burned alive and had a stomach full of undigested sleeping pills, the police eventually ruled the death a suicide, unable to track down any evidence that they could tie to her murder.

But some of the forensic data that can help solve her case still exists. The Isdal Woman’s jaw was preserved in a forensic archive, allowing researchers from the University of Canberra in Australia to use isotopic analysis to figure out where she came from, based on the chemical traces left on her teeth while she was growing up. It’s the first time this technique has been used in a Norwegian criminal investigation.

The isotopic analysis was so effective that the researchers can tell that she probably grew up in eastern or central Europe, then moved west toward France during her adolescence, possibly just before or during World War II. Previous studies of her handwriting have indicated that she learned to write in France or in another French-speaking country.

Narrowing down the woman’s origins to such a specific region could help find someone who knew her, or reports of missing women who matched her description. The case is still a long way from solved, but the search is now much narrower than it had been in the mystery's long history.
