"The most famous self-made man in the world today is our own Edison. Talk with Mr. Edison and he will tell you he owes much if not most of his success to omnivorous reading. Forbes is one of his favorite publications. How closely he reads it can be gathered from a letter just received from him in which he asks the editor to forward a long analytical letter to the writer of a series of articles which contained two figures Mr. Edison questions, and he wants to know exactly on what authority or investigation they were based. Both letters were the product of Mr. Edison and were signed by him."
