🏭 Pemberton Mill

The Pemberton Mill was a large textiles factory in Lawrence, Massachusetts, originally built in 1853. On January 10, 1860, at around 4:30 p.m., a section of the building suddenly collapsed, trapping several hundred workers underneath the rubble, in what has been called "the worst industrial accident in Massachusetts history" and "one of the worst industrial calamities in American history." Of the hundreds crushed under the wreckage, an estimated 88 to 145 of them were killed instantly, and 166 were removed, albeit critically injured.
