Page 715 - In the early days of my electric light, curiosity and interest brought a good many people to Menlo Park to see it. Some of them did not come with the best of intentions. I remember the visit of one expert, a well-known electrician, graduate of Johns Hopkins University. We had the lamps exhibited in a large room, and so arranged on a table as to illustrate the regular layout of circuits for houses and streets. Sixty of the men employed at the laboratory were used as watchers, each to keep an eye on...
Page 537 - I believe that in coming years by my own work and that of Dickson, Muybridge, Marie and others who will doubtless enter the field, that grand opera can be given at the Metropolitan Opera House at New York without any material change from the original, and with artists and musicians long since dead.
Page 537 - In the year 1887 the idea occurred to me that it was possible to devise an instrument which should do for the eye what the phonograph does for the ear, and that by a combination of the two, all motion and sound could be recorded and reproduced simultaneously.
Page 830 - Edison in the specifications of his patent application, "that if sufficient elevation be obtained to overcome the curvature of the earth's surface and to reduce to the minimum the earth's absorption, electric telegraphing or signaling between distant points can be carried on by induction without the use of wires connecting such distant points.
Page 555 - if Edison's experiments, investigations, and work on this storage battery were all that he had ever done, I should say that he was not only a notable inventor, but also a great man.
Page 609 - My methods are similar to those followed by Luther Burbank. He plants an acre, and when this is in bloom he inspects it. He has a sharp eye, and can pick out of thousands a single plant that has promise of what he wants. From this he gets the seed, and uses his skill and knowledge in producing from it a number of new plants which, on development, furnish the means of propagating an improved variety in large quantity. So, when I am after a chemical result that I have in mind, I may make hundreds or...
Page 603 - Edison can think of more ways of doing a thing than any man I ever saw or heard of. He tries everything and never lets up, even though failure is apparently staring him in the face. He only stops when he simply can't go any further on that particular line ( Meadowcroft, 1949, p.
Page 728 - Goebel defense of infringers of Edison's patent of the incandescent lamp: At most they were experimental toys used to advertise his telescope, or to flash a light upon his clock, or to attract customers to his shop. They were crudely constructed and their life was brief; they could not be used for domestic purposes. They were in no proper sense the practical commercial lamp of Edison. . . . It has often been laid down that a meritorious invention is not to be defeated by something which rests in...

Page 862 - Edison's invention was practically made when he ascertained tlie theretofore unknown fact that carbon would stand high temperature, even when very attenuated, if operated in a high vacuum, without the phenomenon of disintegration. This fact he utilized by the means which he has described, — a lamp having a filamentary carbon burner in a nearly perfect vacuum.
