Thomas Edison once wrote the following about his mother:

"I did not have my mother long, but she cast over me an influence which has lasted all my life. The good effects of her early training I can never lose. If it had not been for her appreciation and her faith in me at a critical time in my experience, I should never likely have become an inventor. I was always a careless boy, and with a mother of different mental caliber, I should have turned out badly. But her firmness, her sweetness, her goodness were potent powers to keep me in the right path. My mother was the making of me."
