It only took 15 minutes for the Boston nightclub to become a deadly inferno.

On November 28, 1942, a quick and deadly fire spread through Cocoanut Groves night club. It was the worst nightclub fire in American history.

The club was a fire trap. It was filled to over twice its capacity. Doors were locked to stop patrons sneaking off without paying their bills. Inside, the walls and decor were filled highly flammable materials.

The fire killed 492 people, from burns or smoke inhalation. Another 166 people had burn and smoke injuries.

Cocoanut Grove's fire led to changes in fire regulations, rules around revolving doors, what constitutes a public space, medicinal developments in treating burn patients, and an advance in understanding grief and post-traumatic stress disorder.

Here's how it happened, and what came after the Cocoanut Grove fire.

Its doors first opened in 1927, but because of Prohibition era complications, the club went through several owners, including bootlegger Charles Solomon, known as "Boston Charlie" (he was gunned down in a nightclub) before it landed in the hands of Barney Welansky, Solomon's lawyer.

To turn a profit, Welanski tried to make it more welcoming. He fitted the club with artificial palm trees, leather walls, and cloth-covered ceilings. He had singer Mickey Alpert, the former owner, come back and perform and act as the club's MC. But his changes were superficial, and corners were cut.

According to the Boston Globe, Welansky used unlicensed electricians to fit out the bar, and told a concerned contractor not to worry since he was close with Boston Mayor Maurice Tobin.

The party was canceled but people still came on a chilly New England evening to drink and dance. Hewson Gray told NFPA, "It was so crowded you had to turn sideways to get through the tables in the dining room." By the time the night got going, there were about 1,000 people in the club — twice as many as the legal limit of 460.

Marshall Cole, one of the tap dancers, usually relaxed in the Melody Lounge, the club's basement, between shows. But he told the Boston Globe, "The place was just mobbed. It was standing-room only." He decided to wait in his dressing room, and that saved his life.

Just after 10 p.m. in the Melody Lounge, patrons were singing along to a popular war song with the pianist. A sailor and his date sought some privacy in the already dimly lit bar, and unscrewed a lightbulb to plunge their corner into darkness.

Although it's never been proven, 16-year-old bus boy Stanley Tomaszewski bore the brunt of blame for what happened next. He lit a match to find the lightbulb. When he found it, he stubbed the match out. But a fake palm tree caught alight.

The fire traveled from palm tree to the satin-covered ceiling. The official Boston Fire Department report estimated it took between 2-4 minutes to spread 40 feet, and reach the stairwell, which acted like a chimney. In another minute it had traversed all of the dining room, and engulfed the nightclub.

The fire moved so fast it's still described as a mystery. Casey Grant, executive director emeritus of the Fire Protection Research Foundation, said the shape of the foyer ceiling sent the fire onward, "almost like out of a shotgun." As flames and smoke filled the club, panic ensued.

So many people died because management had locked doors to ensure people didn't leave without paying. Other doors only opened inwards, which made them unusable in the dark. The club's main entrance had a revolving door, which jammed due to the volume of people trying to get out.

But it was chaotic. The street was also filled with police, servicemen, and civilians. US Naval reserveman Nick Pagonis said in a police interview, which was publicly released in 2012, "It seemed to me that all those rescue workers were in the way. They held back those who wanted to help. The whole picture was very disgusting."

Others survived by wetting handkerchiefs and covering their mouths. Daniel Weiss, one of the cashiers, covered his mouth with a soaked bar towel, and stayed close the ground. "The closer I was to the floor, the easier it was to breathe," he said.

In little over an hour, the fire was out. Bodies were passed through the charred windows to waiting soldiers and sailors. It was so cold outside, below freezing, that puddles from the fire hoses froze over.

An AP correspondent wrote, "When the last body was reported out I looked around the room of the ground floor. It was a shambles. Chairs and tables were upended, crockery and glassware was strewn everywhere, it was as if a tornado had whistled through the room."

By midnight, the Cocoanut Grove was a charred, empty building. Despite what had happened within, the structure survived. The Sun called it a "huge brick oven," with little obvious damage to its walls and roof.

Those still alive were sent to two nearby hospitals, Boston City and Massachusetts General. BCH got over 300 casualties, of which 132 lived longer than two hours. MGH got 114, of which 39 survived longer than two hours.

Later calculations worked out that BCH's victims came in at an astonishing rate of one victim every 11 seconds over a 75 minute period.

Because of the scope of the misfortune, neither hospitals charged any of the patients.

At MGH, it was a quiet evening until ambulances arrived, one after another. Surgical register Francis Moore wrote a letter to his parents about the night. He described one young girl "with her clothes burned off, and her skin hanging like ribbons as she flailed her arms around, screaming with pain."

Another man who died from his burns repeated, "I must find her. I must find her."

The next day, cars were still parked down the road. Firemen hosed down the narrow cobbled street, washing away cups and saucers, women's clothing, and hundreds of cocktail forks.

Because of the scope of the burns, identifying victims was difficult. Police went through notebooks and purses to identify who had died. But it took days to sort out who had perished and who had survived. Some people were never identified.

One of the biggest impacts the fire had was on treating burn patients. While BCH continued with the traditional treatment of dyes and tannic acid, MGH Surgeon Oliver Cope and Moore used gauze coated with petroleum jelly. They also did skin grafts. In a report a month later, it found that 30% of those at Boston died from their burn wounds, while none died at MGH.

But the recovery process for some took months or years. In May 1943, eight people were still recovering in the hospital. Clifford Johnson, who tried to save his date, had $50,000 worth of skin grafts and transfusions. This photo shows him exercising in September 1943, about 10 months after the fire.

Welansky was convicted of 19 counts of involuntary manslaughter, which set a legal precedent that someone could be guilty by consciously failing to fix dangerous conditions. He was sentenced to up to 15 years in prison, but was pardoned four years later, two months before he died of cancer.

Fire Marshal Steven Garrity also tried to clear bus boy Tomaszewski of blame in 1943. He said it was possible that screwing the lightbulb had caused the spark, and "suspect" and "shoddy electrical wiring" was potentially at fault. But that didn't stop Tomaszewski's name being mentioned in almost every article about the fire since.

The fire led to developments in grief and post traumatic stress disorder, too. Psychiatrist Erich Lindemann looked into guilt that survivors experience alongside soldiers from World War II, including one man who was wracked with guilt after he fainted before he could save his wife.

The experiences were compiled in the first systematic study of grief.

It was a senseless tragedy, and for those who survived, a life-altering experience. Cole, the tap dancer who waited in his dressing room, told the Boston Herald, "From there on out whenever I go to a place, I look for an exit."
