Query: Thomas Edison better understood, Charles' life explained

I collect Edison phonographs so Thomas Edison always interested me. If you are interested in Edison, this book is excellent because it covers the era when Charles was a boy, when he ran the company, and after Edison died, and it helps explain why TAE was so stubborn. This book serves to tell about Charles who was humble and kept TAE inc from going under after the great depression. This book also tells of an honest politician and the hard times he encountered. If you love history this book is for you.The best thing, this book often sells at a fraction of its value. Charles met his goal, he cast a shadow of his own.
