Edison was nothing but a coward and a thief.
Nevertheless, Tesla displayed the occasional cruel streak; he openly expressed his disgust for overweight people, once firing a secretary because of her weight.
Well, atleast Edison was not cruel.
Edison became a telegraph operator after he saved three-year-old Jimmie MacKenzie from being struck by a runaway train.
Edison saved a three year old boy, and your calling him a coward.

Seriously, please read more about Edison as he is no thief. Tesla has made alot of crazy claims, like Einstein being a theif and stealing the idear of relativity from someone else.
