The 1940 Tacoma Narrows Bridge collapse claimed only 1 victim: a 3-legged dog.

On November 7, 1940 Leonard Coatsworth left his 3-legged, paralyzed cocker spaniel in the back seat of his car. Coatsworth had abandoned the car while crossing the Tacoma Narrows Bridge because the bridge had begun swaying violently. He and a friend attempted to return to the car, but failed due to the strength of the bridge’s motion.

However, a dog-lover named Professor Farquharson managed to safely cross to where the vehicle was parked. His would-be rescue mission failed, though - Tubby was so afraid that he bit Farquharson’s finger as the courageous professor was attempting to save him! This unfortunately left him no choice but to abandon the poor canine, who would eventually plummet 200 feet with the rest of the bridge to his watery grave below.

There is a page on the Washington State Department of Transportation website devoted entirely to Tubby.
