3. HISTORY OF AUTOMOTIVE ACCIDENTS
1869 - Irish scientist Mary Ward was riding in a steam-powered automobile built by her cousins
On turning, on a road a bend, Ward was thrown from her seat and fell in the vehicle’s path
One of the wheels rolled over her and broke her neck killing her instantly
1891 - Engineer James Lambert was driving one of his inventions, an early gasoline-powered buggy
The buggy, also carrying passenger James Swoveland, hit a tree root sticking out of the ground
Lambert lost control and the vehicle crashed, both men suffered minor injuries
1896 - Bridget Driscoll stepped off of a London curb and was struck and killed by a gas-powered Anglo-French model car driven
by Arthur Edsall with a top speed of four miles per hour. The coroner who examined Driscoll’s body is famously quoted as
saying that he hoped “such a thing would never happen again.” (That same year, a bicyclist was killed by automobile in
New York City.)
September 13, 1899: The first pedestrian death in the U.S. occurred on Henry Bliss, according to contemporary accounts, was
(not a Friday) either disembarking from a New York City streetcar or helping a woman step out when he was struck
by an electrically-powered taxi cab. He died from injuries to his head and chest the next morning
1898: The first driver fatality from a collision happened in, when Englishman Henry Lindfield and his son were driving from
Brighton to London. Near the end of their trip, Lindfield lost control of the car while going down a hill
- They crashed through a fence and Lindfield was thrown from the driver’s seat before the car ran into a tree and caught
his leg between them
- His son’s leg was crushed below the knee and decided to amputate it and after the operation, Lindfield remained
unconscious, and died the following day
