101 Years Later: Remembering Boston's Great Molasses Flood of 1919

On January 15, 1919, Boston suffered one of history’s strangest disasters: a devastating flood of molasses. The “Great Molasses Flood” tore through the city's North End and deposited so much gooey residue that locals claimed they could still smell the molasses on warm days decades later.

While most of us probably think of molasses as a tasty ingredient in treats like gingerbread, the sticky stuff has quite a few other uses. With a little know-how, one can turn molasses into rum or industrial alcohol fairly easily, and the Purity Distilling Company had built the gigantic tank in Boston’s North End in 1915 to supply its booze-making operations.

The steel tank was enormous: 50 feet tall, 90 feet across, and capable of holding 2.5 million gallons of molasses. (Although Prohibition kicked in with Nebraska’s ratification of the Eighteenth Amendment the very next day after the 1919 disaster, the United States Industrial Alcohol Company, Purity Distilling’s parent company, still had a license to distill alcohol for industrial applications.)

The massive tank was nearly full on January 15, thanks to a recent infusion of 2.3 million gallons of molasses from Puerto Rico. Just after noon, something went horribly wrong. Witnesses later recalled hearing a noise like gunfire as the tank’s rivets popped and the steel sides ripped open. Suddenly, 26 million pounds of molasses were tearing down Commercial Street in a 15-foot wave.

A shockingly destructive force

A giant wave of a sticky foodstuff sounds like something from a cartoon, but the surging molasses was a shockingly destructive force. The wave moved at upwards of 35 mph, and the power was sufficient to rip buildings off of their foundations. The molasses snapped the support girders from an elevated train track and smashed multiple houses. The Massachusetts Foundation for the Humanities’s website claimed the property damage alone totaled around $100 million in today’s dollars.

The human cost of the disaster was even more grim. The wave of molasses moved so quickly and so forcefully that anyone who was unlucky enough to be in its way didn’t stand much of a chance. They were either knocked over and crushed or drowned in the goo. The flood claimed 21 lives, and another 150 people suffered injuries. Any flood would have been disastrous, but the viscous nature of molasses made rescue attempts even trickier. Medics and police officers arrived on the scene quickly but had to slog through waist-deep goo to reach victims.

Even after the victims had been pulled from the muck, cleanup crews quickly learned that getting rid of 2 million gallons of molasses is no small task. In his book Dark Tide, Stephen Puleo wrote about one of the chief obstacles to the cleanup: firefighters couldn’t just use their hoses to blast the molasses off of buildings and streets with fresh water. Eventually they realized that saltwater would cut the hardened molasses and enable them to hose it down the streets into gutters. Thanks to all the foot traffic of rescue workers, cleanup crews, and rubberneckers, the sticky mess quickly moved around the city via people's shoes. In all, the cleanup effort required over 80,000 man-hours.

The Blame Game

How did this tragedy happen in the first place? The United States Industrial Alcohol Company was quick to blame everyone’s favorite early 20th-century scapegoats: anarchists. The company claimed that since its alcohol was an ingredient in government munitions, anarchists must have sabotaged the tank by detonating a bomb. Another theory explained that the molasses had fermented inside the tank, which led to an explosion.

Investigators soon found the real culprit, though: shoddy construction work. The company had been in such a hurry to get the tank built back in 1915 that it didn’t cut corners so much as it ignored the corners completely. Modern studies have found that the tank walls were both too thin and made of a steel that was too brittle to withstand the volume of molasses.

The man who oversaw the construction wasn’t an engineer or an architect; in fact, he couldn’t even read a blueprint. The tank needed to be an engineering marvel to hold all that weight, but the company never even consulted an engineer on the project. Basically, it threw up a gigantic tank as quickly and as cheaply as possible, skimped on inspections and safety tests, and hoped for the best.

In light of these details, it’s amazing that the tank held together for four years. Nearby residents reported that the tank had leaked since its construction. Rather than fix the problem, the United States Industrial Alcohol Company had painted the tank brown so the leaks would be less noticeable.

The largely working-class North End residents who had lost their homes and loved ones in the disaster predictably turned their rage toward the United States Industrial Alcohol Company. USIA soon found itself named as the defendant in 125 lawsuits, which led to a legal battle that nearly matched the flood’s scale.

The Massachusetts Superior Court named Colonel Hugh Ogden as the auditor who would hear the evidence and report back on the cause of the disaster. It took Ogden nearly six years to hear testimony from 3000 witnesses. When he finally penned his report, he concluded that there was no evidence to support the company’s theory of anarchist saboteurs. Instead, Ogden found that the “factor of safety” in the tank’s construction and inspection had been woefully low. USIA was liable for the damage and paid around $7000 to the family of each victim.

The Great Molasses Flood still seems like a tragedy that could have been averted, but the disaster really drew attention to the potential repercussions of shaky construction. The case helped prompt Massachusetts and many other states to pass laws requiring that engineers and architects inspect and approve plans for major construction projects.

Alice Dunnigan, the First Black Woman Journalist to Get White House Press Credentials

Alice Dunnigan’s birthplace of Russellville, Kentucky, is more than 700 miles from Washington, D.C. And for Black women journalists in the early 20th century, the dream of heading to the Capitol and covering national politics at the highest level seemed even more distant. But Dunnigan overcame racism, sexism, and other obstacles to make history as the first Black woman credentialed to cover the White House. Dunnigan, whose grandparents were born into slavery, would combat discrimination and champion freedom of the press while covering three U.S. presidents.

A Long Road to Writing Success

Born on April 27, 1906, Alice Allison Dunnigan grew up in a cottage on a red clay hill outside Russellville, a former Confederate Civil War stronghold (population 5000). Dunnigan’s father was a tenant farmer, while her mother took in laundry. Their precocious daughter learned to read before entering the first grade, and she began writing for the Owensboro Enterprise when she was just 13. After graduating from the segregated Knob City High School in 1923, she completed a teaching course at Kentucky State University.

During Dunnigan’s 18-year career as a Todd County teacher, her annual salary never topped $800. Her aspirations went beyond teaching: She wrote “Kentucky Fact Sheets,” highlighting Black contributions to state history that the official curriculum omitted, and took journalism classes at Tennessee A&I College (now Tennessee State University). Her two marriages to tobacco farmer Walter Dickenson in 1925 and childhood pal Charles Dunnigan in 1932 did not pan out. To pursue her career, she made the tough decision to have her parents raise Robert, her son from her second marriage, for 17 years. In 1935, she moved to Louisville, Kentucky, where she worked for Black-owned newspapers like the Louisville Defender.

With the Jim Crow era still in force and World War II raging, Dunnigan made her next big move to Washington, D.C., in 1942. Vying to escape poverty, she joined the federal civil service and earned $1440 a year as a War Labor Board clerk. Yet even four years later, when she was working as an economist after studying at Howard University and commanding a $2600 salary—double that of the average Black woman in the nation's capital—journalism kept calling her name.

Dunnigan became a Washington, D.C., correspondent in 1946 for the Associated Negro Press (ANP), the first Black-owned wire service, supplying more than 100 newspapers nationwide. It was her ticket to covering national politics.

Fearlessly Covering the White House

Dunnigan’s passion for journalism didn’t boost her bank account. Claude A. Barnett, her ANP publisher, gave her a starting monthly salary of $100—half of what his male writers earned. “Race and sex were twin strikes against me,” Dunnigan said later. “I’m not sure which was the hardest to break down.” To stay afloat financially, she often pawned her watch and shoveled coal, subsisting on basic food like hog ears and greens. To relax, she drank Bloody Marys and smoked her pipe.

Named ANP’s bureau chief in 1947, Dunnigan forged ahead as a political reporter despite Barnett’s skepticism. “For years we have tried to get a man accredited to the Capitol Galleries and have not succeeded,” Barnett told her. “What makes you think that you—a woman—can accomplish this feat?” Though the ANP had never endorsed her application for a Capitol press pass, Dunnigan's repeated efforts finally paid off. She was approved for a Capitol press pass in July 1947, and swiftly followed up with a successful request for White House media credentials.

In 1948, Dunnigan became a full-fledged White House correspondent. When she was invited to join the press corps accompanying President Harry S. Truman’s re-election campaign, Barnett declined to pay her way—so Dunnigan took out a loan and went anyway. As one of just three Black reporters and the only Black woman covering Truman’s whistle-stop tour out West, she experienced highs and lows.

In Cheyenne, Wyoming, when Dunnigan tried to walk with other journalists behind Truman’s motorcade, a military officer, assuming she was an interloper, pushed her back toward the spectators. Another journalist had to intervene on her behalf. Afterward, Truman found her typing in her compartment on the presidential Ferdinand Magellan train and said, “I heard you had a little trouble. Well, if anything else happens, please let me know.”

Dunnigan later landed a scoop in Missoula, Montana, when Truman got off the train at night in his dressing gown to address a crowd of students. Her headline read: “Pajama Clad President Defends Civil Rights at Midnight.”

Her relationship with President Dwight D. Eisenhower in the 1950s was more contentious. The two-term Republican president disliked her persistent questions about hiring practices that discriminated against Black Americans, segregation at military base schools, and other civil rights issues. Max Rabb, an Eisenhower advisor, told her she should clear her questions with him in advance to get better answers. She agreed once, but never again. Subsequently, “Honest Ike” ignored Dunnigan at press conferences for years, despite her status as the first Black member of the Women’s National Press Club (1955).

When President John F. Kennedy took office in 1961, he called on Dunnigan eight minutes into his first press conference. She asked about protection for Black tenant farmers who had been evicted from their Tennessee homes simply for voting in the previous election. JFK replied, “I can state that this administration will pursue the problem of providing that protection, with all vigor.” Jet magazine then published this headline: “Kennedy In, Negro Reporter Gets First Answer in Two Years.”

New Career, New Achievements

Later in 1961, Dunnigan found a new calling. President Kennedy appointed her to his Committee on Equal Opportunity, designed to level the playing field for Americans seeking federal government jobs. As an educational consultant, Dunnigan toured the U.S. and gave speeches. In 1967, she switched over to the Council on Youth Opportunity, where she spent four years as an editor, writing articles in support of young Black people.

After retiring, she self-published her 1974 autobiography, A Black Woman’s Experience: From Schoolhouse to White House. Dunnigan died at age 77 in 1983, but her legacy lives on. In 2013, she was posthumously inducted into the National Association of Black Journalists Hall of Fame. CNN’s April Ryan, Lauretta Charlton of the New York Times, and others have hailed her as an inspiration.

In 2018, a 500-pound bronze statue of Dunnigan was unveiled at the Newseum in Washington, D.C. Today, it stands outside the Struggles for Equality and Emancipation in Kentucky (SEEK) Museum in her native Russellville—a silent but powerful tribute to a woman who was never short on words.
