Nikola Tesla Letters
June 4th, 1931 letter from W. K. Dunlap to Nikola Tesla
Westinghouse Electric & Manufacturing Company
East Pittsburgh, Pa.
Acting Vice President
June 4, 1931
My dear Mr. Tesla:
On this your seventy-fifth anniversary, it must be with no little pride and gratification that you realize how much the inventions which you made in the decade prior to 1890, culminating in the numerous patents issued to you covering generators, motors, transformers, transmission systems, etc. now known to the art as the Polyphase System, have done to advance the welfare of your fellow man.
It was your work which made possible at so early a date the successful development at Niagara, the pioneer in the adoption of your system on a large scale and the forerunner of the tremendous electrical power industry which has grown up throughout the civilized world and without which modern life as we know it would be impossible.
With heartiest congratulations and best wishes, I remain
Most sincerely yours,
Mr. Nikola Tesla
New York, New York
