The "Famous Engineers" Series

 
The Prolific Inventor
 
By simply flicking a switch, you can turn on a light in your house, watch a show on television or toast bread in a toaster.  For that we can thank a determined engineer from New York - one of the most prolific inventors in U.S. history.
 
Born in 1846, he ran away to join the Union army at the age of 15.  After the end of the Civil War in 1865, he studied engineering at Union College.  It was here that he obtained a patent for a rotary steam engine - his first of 361 patents.
 
After witnessing a train accident, this son of a Schenectady, NY factory owner obtained a patent in 1869 for the world's first air brake system - the system that is still in use today in trains and trucks.  At the young age of 22, he formed a company to sell his air brake invention - the first of more than 60 companies that he founded.
 
However, his most profound impact on society came from his work with AC power, which competed directly with Thomas Edison's low-voltage DC power distribution system.  His battle with Edison's DC systems, called "The War of Currents", was ruthless.  It would eventually lead to the use of electrocution as a means of executing prisoners in the state of New York.
 
His many accomplishments included developing:  the first long distance electrical distribution system (between Niagara Falls and Buffalo NY), the first city-wide telephone switching system, the world's first radio station, and the world's first practical induction motor.
 
Just as impressive as his technical and business accomplishments, he began in 1871 to give his employees a half day-off on Saturdays - the first step towards a five-day work week. 
 
Who was this brilliant engineer and inventor? 
 
And how did the "electric chair" figure into his battle against Edison's DC systems?
