95 Years Later: Remembering the Sticky Horror of the Boston Molasses Flood 

There is no shortage of forgotten disasters, but few rival the 1919 Great Boston Molasses Disaster in the scope of its strangeness and the small memory of it in the place it totally destroyed.

Today is the 95th anniversary of the January 15, 1919 catastrophe, when a massive steel tank holding some 26 million pounds of molasses broken open, crashing a wave of sticky substance stretching up to 25 feet tall and 160 feet wide. It’s a story that starts as an amusing anecdote — a sugary sea spreading through the streets — but quickly turns into a nightmare of almost unimaginable proportions. Moving at 35 miles per hour, the wave engulfed absolutely everything in its path, including people who were strolling through the afternoon streets on an unusually warm day. The legs of the elevated tracks were broken, houses and buildings were obliterated into shards, horses, as reported by the Boston Post, “died like so many flies on sticky fly paper.”

In the aftermath, 21 people were dead, 150 injured, and rescue was exceeding slow, as of course molasses movement is known to be. The molasses seeped into the infrastructure, and even now on hot days people in the North End area claim to smell a whiff of molasses in the air. The disaster was at first blamed on anarchists — as disasters in early 20th century America tended to be — but was later revealed to be shoddy construction.
