5 Other Famous Gate Crashers

Original image

It takes a certain kind of chutzpah to crash high profile events. Aspiring reality show stars Tareq and Michaele Salahi, who crashed a state dinner at the White House last week, are just the latest in a long line of publicity-starved trespassers.

1. David Hampton

David Hampton crashed his first gate in 1983 when he was denied entrance to the famously selective disco Studio 54. On the spur of the moment, he informed the bouncer that he was, in fact, David Poitier, son of Academy Award winning actor Sidney Poitier. He was not only immediately ushered inside the club, he was also given the full celebrity treatment. Once he got a taste of the high life, he used his new persona to nab free meals at five star restaurants and to borrow money from and couch-surf at the homes of such celebs as Melanie Griffith, Gary Sinise and Calvin Klein. Hampton was eventually arrested and served time in prison for fraud. His exploits were the inspiration for John Guare's acclaimed play Six Degrees of Separation.

2. Barry Bremen

gatecrasher2
Barry Bremen, a marketing executive from West Bloomfield, Michigan, craves the limelight. He nearly made it to the stadium floor at the 1982 Super Bowl by dressing as the San Diego Chicken. He dressed as an umpire in 1980 and confabbed at home plate with Harry Wendelstedt and Don Denkinger at a World Series game before being discovered. He even once crash dieted 23 pounds off of his 6'4" frame, shaved his legs and spent $1,200 on a custom-made Dallas Cowboys Cheerleader costume. He infiltrated Texas Stadium and managed a "Go Cowboys!" yell before security handcuffed him.


Perhaps his most daring escapade came at the 1985 Emmy Awards. Dressed in a tuxedo, he purchased a single $300 ticket for the ceremony and found himself seated in Row Three. As the show progressed, he noted that many of the winners were seated further back in the auditorium and it took them a few minutes to reach the stage. When Betty Thomas' name was announced for Outstanding Supporting Actress (Hill Street Blues), Bremen jumped out of his seat, loped to the stage and accepted the statue, explaining that Thomas was unable to attend. He was arrested backstage (with a confused Betty Thomas looking on) and spent an hour in jail before posting bail.

3. Michael Fagan

To tourists craning their necks at the front gate to see the changing of the guards, Buckingham Palace seems like an impenetrable fortress. But with a combination of determination and plain dumb luck, 31-year-old Michael Fagan bypassed all the security measures in place and ended up in the bedroom of Queen Elizabeth II.

Early in the morning of July 9, 1982, Fagan scaled the 14-foot wall (topped with barbed wire) on the southeast side of the Palace. He climbed inside an open window and then wandered along various corridors. He tripped a silent alarm twice, but both times Palace security simply turned it off, thinking it was an electrical malfunction. He eventually found the unlocked door of the Queen's bedroom and entered. The footman who normally stood guard was outside walking her corgis at the time. Her Majesty awoke to find a strange man sitting on the foot of her bed. With praiseworthy aplomb, she engaged him in conversation and kept him calm; when he asked for a cigarette it gave her an excuse to summon a footman, and Fagan was summarily arrested.

4. Paul Goresh

Paul Goresh is the very rare exception to the gate-crashing rule; rather than being arrested, he eventually befriended his target. Goresh was a New Jersey college student, amateur photographer and Beatles fan who came up with a plan to meet his idol, John Lennon. Goresh boldly gained access to the exclusive Dakota apartment building one day in 1979 by dressing in an ersatz uniform and informing the security guard that he was there to repair the Lennon's VCR. He was allowed upstairs, and to Paul's amazement, John Lennon himself actually answered the door. Lennon was confused and upset that his secretary hadn't alerted him that a repairman was expected (one wasn't, of course; the whole thing was a farce). Surprisingly, John felt bad about his verbal outburst and apologized to Goresh and obliged him with an autograph.

In the following months, John and Yoko frequently saw Goresh hanging around outside the Dakota with his camera and John accused him of being a member of the press (this was during John's reclusive "househusband" period). Goresh insisted that he was merely a fan and offered up his roll of undeveloped film as proof. John exposed the roll and gatecrasher4Goresh's only request that he didn't break his camera, as it cost $350. Lennon and Goresh developed something of a casual friendship after that—John and Yoko would frequently pose or wave when they spotted him in front of the Dakota.


Little did Paul Goresh suspect that he would become a footnote in history when he snapped a photograph of John Lennon signing a copy of Double Fantasy for Mark David Chapman on the evening of December 8, 1980 (pictured).

5. Aaron Barschak

The motives behind self-proclaimed "comedy terrorist" Aaron Barschak's various antics (he's successfully crashed several A-list London parties) seem to change depending upon his mood when he's interviewed. He was either paying silent tribute to British comedian Spike Milligan, or he was afraid of dying without anyone knowing his name. Whatever his reasons, he became a household name in the UK after he crashed Prince William's 21st birthday party in August 2003. Dressed as Osama bin Laden (albeit with a pink skirt), he scaled the wall of Windsor Castle, set off several alarms, was seen by security on closed-circuit television and still managed to get on stage while Will was giving a speech. He was apprehended but not charged; instead a serious investigation into royal security was launched.

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.
