75 Workers Died Because This Engineer Chose Profit Over Safety

Ajouté : 2026-05-23

[00:00:00]In 1907, 75 men went to work on the Quebec Bridge. By the end of the day, they were all dead.

[00:00:06]Chief engineer Theodore Cooper had been getting telegrams for weeks. The bridge's steel beams were bending, deflecting under their own weight.

[00:00:13]Cooper ordered the work to continue anyway. On August 29th, the workers heard something terrifying. The steel was talking, creaking, groaning under stress. They begged their foreman to stop construction. He refused. At 5:47 p.m., the entire south span began to fold.

[00:00:29]150 ft of bridge collapsed in 15 seconds, like a house of cards made of steel. 75 men plunged into the Saint Lawrence River, trapped under thousands of tons of twisted metal. Cooper had been cutting costs, using steel that was 30% underweight. When investigators arrived, they blamed unforeseen circumstances, a complete cover-up. Nine years later, the same bridge collapsed again, 13 more dead. The Quebec Bridge disaster became the deadliest construction accident in North American history, all because one man chose deadlines over lives.
