"There was something Napoleonic, also, about Edison's intensity of application and his masterfulness in his gigantic undertakings. If genius is the ability to take great pains, Thomas A. Edison is the greatest genius in the world to-day--if not in all history. ”

“ Edison allowed himself was when he traveled to the Rocky Mountains to witness a total eclipse of the sun and experiment on certain stars with his tasimeter, and this very clearly shows that Mr. Edison is as much interested in the advancement of science as in matters purely commercial. ”

“ Those who do really great things along the lines of physical improvement, or concerning the inception of large enterprises are apt to startle the public and to surprise thoughtful people almost as though some impossible thing had been achieved.
"From a mere salaried operator to forty thousand dollars in a lump sum for expert work was quite a jump.
"The forty thousand dollars, however, did not turn Mr. Edison's head as has been the effect of sudden wealth on many a good-sized but smaller minded man. ”
