Mr. Fritz's more than 89 years have covered the most eventful era in the world's history; in fact, it is hard to realize that any one life could have witnessed so many and such wonderful achievements; —placing on a practical basis the construction and operation of steam and electric rail¬ ways; the invention of the electric telegraph; that of the daguerreotype, and the art of photography; the laying and operation of ocean cables; electric lighting; the telephone; the phonograph; and the other wonderful electrical en¬ gineering developments — perhaps the most startling of all — wireless telegraphy; the making actual of submarine navigation; and the until lately unbelievable science of aviation. In Mr. Fritz's own particular field of engineering, he witnessed the discovery, and participated in the develop¬ ment of the epoch-making Bessemer process, followed by the Acid and Basic Open-hearth, and now the electric furnace; and besides those, the other tremendous develop¬ ments in the Iron and Steel arts, in which he was an active factor.
It is fortunate that the incidents of such a life should be recorded in Mr. Fritz's own way and in his own words; and speaking for those of us who are left of the many who were associated with him and therefore who knew and loved him, I thank him for this his latest work.
