The Great Smog Descended on London 65 Years Ago, and Took Almost as Long to Solve

Heavy fogs have long been a part of life in London. In his novel Bleak House, Charles Dickens wrote:

“Fog everywhere. Fog up the river where it flows among green airs and meadows; fog down the river, where it rolls defiled among the tiers of shipping, and the waterside pollutions of a great (and dirty) city ... Chance people on the bridges peeping over the parapets into a nether sky of fog, with fog all round them, as if they were up in a balloon and hanging in the misty clouds.”

Yet a full 100 years after the celebrated author wrote those words, the city would become enveloped in a dangerous mix of fog and smoke—the likes of which they had never experienced, and were not prepared for. When the smog finally lifted, thousands of people were dead. And it would take nearly 65 years for scientists to pinpoint the reason for what has become known as The Great Smog of 1952, one of the deadliest environmental disasters in the history of the world.

December 5, 1952 started out just like any other day in London, albeit a tremendously foggy one. But as the day wore on, it became clear that there was something different about the darkness that had descended on the city, which would hang there until December 9. People who were caught outside in the weather found themselves gasping for air, barely able to open their eyes from the sting the smoky atmosphere was delivering. Those who could see couldn’t see very far; as visibility dwindled to practically zero, pedestrians had trouble seeing their own feet while motorists were forced to abandon their vehicles.

For several days, the city was essentially shut down. It all began with a cold front, which led more and more Londoners to crank up their coal stoves and gather around them for warmth. While the smoke from the city’s chimneys would normally disperse into the atmosphere, a lack of wind and an unfortunately timed anticyclone positioned over the city ended up trapping the smoke, which mixed with the fog and other pollutants, creating a lethal atmosphere.

“You had this swirling,” funeral director Stan Cribb told NPR in 2002, “like somebody had set a load of car tires on fire.” Cribb, who at the time was working as a mortician’s assistant, was on his way to a wake with his uncle—who was also his boss—with a line of mourners behind them. According to NPR:

Neither man knew a catastrophe was brewing. They didn't know that a mass of stagnant air had just clamped a lid over London, trapping the smoke from millions of residential coal fires at ground level.

Cribb remembers being stunned by the blackness of the gathering fog. After a few minutes he couldn't see the curb from his spot behind the wheel. After a few more minutes, Tom Cribb got out and started walking in front of the hearse, to keep his nephew on the road. He carried a powerful hurricane lantern in one hand, but it was useless.

“It's like you were blind,” says Cribb.

When the fog finally lifted, reports estimated that at least 4000 people had been killed and 150,000 were hospitalized, though in the years since the total death toll has risen to approximately 12,000.

Fans of the Netflix series The Crown will likely remember the 2016 episode in which Queen Elizabeth and then-Prime Minister Winston Churchill were forced to contend with the deadly event. (Of course, always aiming for accuracy, director Stephen Daldry told Entertainment Weekly that they weren’t about to use CGI to recreate The Great Smog. “We had to get a great, huge warehouse and fill it full of fog to create the great pea soup of 1952,” Daldry said. “We did it for real—CG didn’t look good enough for us.”)

Amazingly, it wasn't until last year—just a few weeks before The Crown premiered—that a global team of scientists announced that they may have finally solved the mystery of The Great Smog, and published their findings in the November 2016 issue of Proceedings of the National Academy of Sciences (PNAS).

“People have known that sulfate was a big contributor to the fog, and sulfuric acid particles were formed from sulfur dioxide released by coal burning for residential use and power plants, and other means,” said Dr. Renyi Zhang, a professor at Texas A&M University and one of the paper’s lead authors. “But how sulfur dioxide was turned into sulfuric acid was unclear. Our results showed that this process was facilitated by nitrogen dioxide, another co-product of coal burning, and occurred initially on natural fog. Another key aspect in the conversion of sulfur dioxide to sulfate is that it produces acidic particles, which subsequently inhibits this process. Natural fog contained larger particles of several tens of micrometers in size, and the acid formed was sufficiently diluted. Evaporation of those fog particles then left smaller acidic haze particles that covered the city.”

In addition to helping to solve a troubling environmental disaster that had confounded scientists for decades, Zhang and his colleagues’ research is also helping to determine how to best deal with similar air pollution problems today, including those faced by several cities in China, which is home to some of the world’s most polluted cities.

“The difference in China is that the haze starts from much smaller nanoparticles, and the sulfate formation process is only possible with ammonia to neutralize the particles,” Zhang said. “In China, sulfur dioxide is mainly emitted by power plants, nitrogen dioxide is from power plants and automobiles, and ammonia comes from fertilizer use and automobiles. Again, the right chemical processes have to interplay for the deadly haze to occur in China. Interestingly, while the London fog was highly acidic, contemporary Chinese haze is basically neutral.”

“The government has pledged to do all it can to reduce emissions going forward, but it will take time,” he added. “We think we have helped solve the 1952 London fog mystery and also have given China some ideas of how to improve its air quality. Reduction in emissions for nitrogen oxides and ammonia is likely effective in disrupting this sulfate formation process.”

Though it would be hard to call it a silver lining, The Great Smog of 1952 did have one positive effect: it forced the country’s government, and its people, to become more aware of the impact their actions had on their environment. On July 5, 1956, less than four years after London was enveloped in a lethal darkness, the Queen enacted the Clean Air Act 1956, which banned the burning of pollutants across the UK.

16 Soothing Facts About Muzak

Whether you know it as background music, elevator music, or, as Ted Nugent once called it, an “evil force causing people to collapse into uncontrollable fits of blandness,” Muzak has ruled speakers for the better part of a century. Press play on your favorite easy-listening album and scroll on for some unforgettable facts about the most forgettable genre of music.

1. Muzak is a brand name.

Much like Chapstick, Popsicle, and a certain type of vacuum-sealing plastic food container, Muzak is a registered trademark. It began as the name of the company that first produced the easy-listening instrumental tunes that played in factories, elevators, and department stores. As its popularity grew, people started to use Muzak as a generic term for all background music.

2. Muzak was invented by a U.S. army general.

During World War I, Major General George Owen Squier used electrical power lines to transmit phonograph music over long distances without interference. He patented this invention in 1922 and founded Wired Radio, Inc. to profit from the technology. The company first devised a subscription service that included three channels of music and news and marketed it to Cleveland residents for $1.50 per month. When Squier and his associates realized their product was a little too close to regular (free) radio, they started pitching it to hotel and restaurant owners, who were more willing to pay for a steady broadcast of background music without interruptions from radio hosts or advertisements.

3. The name is a portmanteau of music and Kodak.

In 1934, Squier changed the name of his business from Wired Radio to Muzak, combining the first syllable of music with the last syllable of Kodak, which had already proven to be an extremely catchy, successful name for a company.

4. Muzak has been releasing instrumental covers of pop songs since its inception.

The first-ever original Muzak recording was an instrumental medley of three songs performed by the Sam Lanin Orchestra: “Whispering,” by John and Malvin Shonberger, “Do You Ever Think of Me?” which was covered by Bing Crosby, and “Here in My Arms,” by Lorenz Hart and Richard Rodgers from the 1925 Broadway musical Dearest Enemy.

5. Muzak was briefly owned by Warner Bros.

The sound of Muzak was wafting across the country by the end of the 1930s, which caught the ears of Warner Bros. The company bought Muzak in 1938, fostered it for about a year, and then sold it to three businessmen: Waddill Catchings, Allen Miller, and William Benton (Benton would later publish the Encyclopaedia Britannica and serve as a U.S. senator for Connecticut).

6. Muzak was designed to make factory workers more productive.

Muzak manufactured soundtracks, based on a theory called “stimulus progression,” that consisted of 15-minute segments of background music that gradually ascended in peppiness. The method was meant to tacitly encourage workers to increase their pace, especially during the productivity lulls that often occurred during the late morning and mid-afternoon.

7. Muzak helped calm anxious elevator passengers.

Since more advanced electric elevators diminished the need for elevator operators in the mid-20th century, passengers were often left alone with an unsettling silence that made them all too aware that they were hurtling upward or downward in a steel box. Soft, calming Muzak played through speakers offered the perfect distraction.

8. There’s a reason Muzak's tempo is slower in supermarkets.

Just like factory workers might move faster while listening to fast-paced tracks, you might slow down while shopping to slower-tempo Muzak—which is exactly what supermarket owners want you to do. The more time you spend in a store, the more likely you are to toss a few extra snacks in your cart. (It's unclear whether the slower music might inhibit the productivity of supermarket workers.)

9. More than one U.S. president endorsed Muzak.

Muzak was installed in the White House during Dwight D. Eisenhower’s administration, but he was arguably only the second biggest presidential fan of the genre. Lyndon B. Johnson actually owned Muzak franchises in Austin while serving as a U.S. Senator from Texas.

10. Andy Warhol was also a fan of Muzak.

Pop culture aficionado Andy Warhol supposedly said, “I like anything on Muzak—it’s so listenable. They should have it on MTV.”

11. Ted Nugent offered to buy Muzak for $10 million to “shelve it for good.”

In 1986, the Whackmaster put in a bid to purchase Muzak from parent company Westinghouse just to shut it down. According to the Ottawa Citizen, he called it an “evil force” that was “responsible for ruining some of the best minds of our generation.” Westinghouse rejected the bid.

12. Muzak didn’t formally introduce vocals until 1987.

As part of a rebranding campaign to modernize Muzak, the company started adding voice-accompanied tunes in 1987. Before that, Muzak broadcasts had only featured voices twice. The first was an announcement that Iran had freed American hostages in 1981, and the second was as part of a worldwide radio broadcast of “We Are the World” in 1985.

13. 7-Elevens blared Muzak in parking lots to chase off loiterers.

In 1991, 7-Eleven parking lots in Southern California became well-trafficked watering holes for youth who evidently had no place else to go. To deter them from loitering with skateboards, beer, and lots of teen angst, the stores blared Muzak—and it worked. “It will keep us away,” one young loafer told the Los Angeles Times. “But they’re torturing themselves more than us because they have to sit inside and listen to it.”

14. Seattle is the capital of Muzak.

Though it's well known as the birthplace of grunge, Seattle also had a thriving elevator music scene. Muzak based its corporate headquarters there in the 1980s, and three other leading background (and foreground) music corporations opened in the city over the years: Yesco Foreground Music, Audio Environments Inc., and Environmental Music Service Inc.

15. Kurt Cobain wanted Muzak to cover Nirvana songs.

When an interviewer told the Seattle-based rock star that Muzak didn’t recreate Nirvana tracks because it found them too aggressive for its purposes, an amused Cobain said, “Oh, well, we have some pretty songs, too. God, that’s really a bummer. That upsets me.”

16. It’s no longer called Muzak.

In 2013, an Ontario-based sensory marketing company called Mood Media acquired Muzak. The company, which provides music, smells, signs, lights, and interactive displays to businesses to achieve a certain mood, consolidated all of its services under the Mood brand, effectively killing the Muzak name (at least officially).

The History Behind 7 New York City Street Names

Modern life means constantly rushing to get places, especially in New York. Whether it’s the daily grind to get to work or the rush to hit happy hour, residents are probably concentrating more on getting somewhere than carefully considering the details of their surroundings.

But next time you're in New York—or if you're a resident already—try looking up from your phone to take a peek at the street names above you. Along with your more common numbered designations and things like "Park Avenue," you’ll notice the city has some pretty strange denominations. Here are seven of the more eye-catching, and the brief history behind their names.

1. Asser Levy Place

Tucked between the generically named 23rd and 25th streets, Asser Levy Place stands out like a sore thumb. Located not far from Stuyvesant Town, this unassuming street bears the name for a pretty prominent historical figure.

Said to have been born in what is now Poland and Lithuania, Asser Levy was one of the first Jewish settlers to land in the predominantly Dutch New Amsterdam. The governor at the time, Peter Stuyvesant, was “violently opposed” to the freshly emigrated Jewish community, unhappy at the fact that they were now allowed to trade and reside within the area [PDF]. Levy was not only the first kosher butcher in the land but also the first Jew to gain rights of citizenship in the country. Additionally, Levy donated funds to help New York fight the British Crown, and eventually took up arms against the British himself.

2. Maiden Lane

The history behind Maiden Lane’s designation is just as picturesque as it sounds. Known to Dutch settlers as Maagde Paatje (or “maiden path”), this portion of land once ran alongside a brook where women and girls would wash clothing. There are darker associations with the area too, though: Maiden Lane also saw a brutal slave revolt in 1712.

Today the street is one of many centers of commerce for the city, although the concrete still holds remnants of the city’s more ornate past. Passersby can take a look at the Barthman Clock, a 19th-century timepiece embedded into the intersection of Maiden Lane and Broadway.

3. Mott Street

Located primarily in the heart of Chinatown, Mott Street’s modern associations aren’t the most flattering. Once the site of multiple crime scenes and illegal activities, the street has garnered a somewhat seedy reputation over time.

But before it became affiliated with the seedy underbelly, Mott Street had patriotic associations. Joseph Mott, the street’s namesake, owned a tavern used as headquarters for General George Washington in 1775. His descendants proved dedicated to equally worthy causes, with Dr. Valentine Mott rising to prominence as one of America’s most influential surgeons.

4. Pearl Street

Before the concrete jungle fully took over, the streets of New York were dominated by oysters. Due to their bountiful number, the shells of shucked clams would pile up into what archaeologists call middens—large piles of domestic waste that have survived the centuries. One particularly large heap was located on the modern-day Pearl Street, giving rise to the mollusk-related moniker. Oddly, however, these oysters were not the pearl-producing kind—although they dominated a good portion of the New York market for quite some time.

5. Minetta Lane

Speaking of water-related items, did you know a once-babbling creek was paved over by one of the city’s more famous streets? That’s right: Known to the Dutch as Mintje Kill or “small stream,” Minetta Brook was “[a] brisk little brook full of trout,” according to one 19th century source, that was covered by the city’s expansion around the 1820s. It was also where a community of “half free” African Americans resided in the 17th century—former enslaved people that were allowed to live on the land by paying annual fees.

6. MacDougal Street

MacDougal Street is known for its vibrant nightlife and for hosting the early days of Bob Dylan’s career. But it also holds claim to a not-so-well-known spelling error.

The street was named for one Alexander Mcdougall, a Scotsman who emigrated to what would become the United States as a child in 1740 and settled in New York. Mcdougall made a name for himself in the mercantile trade and shipping business and was an early defender of American independence. He openly voiced his opinions against British rule, and was even imprisoned for passing out revolutionary pamphlets. His colorful life saw him commissioned as a colonel in the First New York Infantry during the Revolutionary War, become a member of the Continental Congress, and rise as the first president of the Bank of New York. However, how or why the second L in his name was dropped in the naming of the street remains a mystery.

7. Margaret Corbin Drive

Located at the city’s far northern tip, Margaret Corbin Drive is named for a young Pennsylvanian woman whose tough life molded her into a tougher lady. Her childhood saw the death of her father by Native Americans and her mother’s capture soon after; years later, the British killed her husband during the Battle of Fort Washington. Margaret, who was standing by his side at the time, quickly took his place in the conflict by handling his cannon—receiving several bullets as a result.

The U.S. government recognized her bravery by providing her disability compensation (as well as rum and whiskey rations) for many years. Although sometimes remembered as a “haughty and disagreeable eccentric,” the affectionately called “Captain Molly” is forever memorialized by the street running along the site where her brave acts took place.
