Thomas Alva Edison was a deaf person. He was removed from school by his teacher as his mind always kept wandering. He was taught at home by his mother and according to him, he learnt the most from a book by RG Parker, ‘School of Natural Philosophy’.
He is known for inventing the first commercially practical light bulb. He failed a thousand times before inventing it but he never said that he failed. Instead, he said,
" I have not failed a thousand times, but I have successfully found a thousand ways how not to make a light bulb."
