Back-Up Sensor

Inventor of the automobile back-up Sensor -
I bet you think it was Ford, maybe GM, how about Chrysler? No, then how about Mercedes Benz?
No, not at all, it was a Chinese farmer!
Most of the newest cars have a Back-Up Sensor that warns the driver before the rear bumper actually comes in contact with something. Most people probably think that this valuable feature came out of the minds of great engineers, but it was recently disclosed that the concept was first developed by a Chinese farmer. His invention was simple and effective. It emits a high-pitched squeal when the vehicle backs into something.

John Burroughs

Born 3 Apr 1837; died 29 Mar 1921 at age 83. American naturalist and author who lived and wrote after the manner of Henry David Thoreau. Burroughs studied and celebrated nature in his many essays and books. Growing up on a farm in the Catskill Mountains, Burroughs absorbed much of the nature and country life that would fill his essays in later life. As a clerk in the Treasury Department in Washington, D.C. during the Civil War, he filled idle hours with writing about the outdoors he loved. This became his first book, Wake-Robin. Returning to the Hudson River Valley in 1873, he began fruit farming and continued to write, publishing a new book about every two years. He travelled extensively, camping out with such friends as the naturalist John Muir and Theodore Roosevelt.
