Tributes to Tesla
Ernst F.W. Alexanderson:
    "In almost every step of progress in electrical power engineering, as well as in radio, we can trace the spark of thought back to Nikola Tesla. There are few indeed who in their lifetime see realization of such a far-flung imagination."

Edwin H. Armstrong:
"During wartime there was much research under way toward reducing the Tesla concept of the guided weapon in various laboratories. . . . So far as I know, the credit for the concept rests entirely with him."

Lee de Forest:
"If I could be any other man I would be Nikola Tesla."

John Stone Stone:
". . . the more we learn about high frequency phenomena, resonance and radiation today, the nearer we find ourselves approaching what we at one time were inclined, through a species of intellectual myopia, to regard as the fascinating but fantastical speculations of a man who we are now compelled . . . to admit was a prophet."

Charles F. Scott:
"The evolution of electric power from the discovery of Faraday in 1831 to the initial great installation of the Tesla polyphase system in 1896 is undoubtedly the most tremendous event in all engineering history."

Thomas Commerford Martin:
"Tesla's influence may truly be said to have marked an epoch in the progress of electrical science."
