Dexter Marshall was a long-time newspaper man, managing editor of the Philadelphia Press and later of the McClure Newspaper Syndicate (Electrical World, Volume 64). He probably had many occasions to interview Nikola Tesla and felt that Tesla's public perception was not correct.

OUR NEW YORK LETTER
----------NIKOLA TESLA, ELECTRICIAN, HIS
AIMS AND ACHIEVEMENTS.
----------
Whether Genius or Charlatan, He Is
One of the Most Thoroughly Misun-
derstood Men Now Living on All
This Green Earth.

This does not mean that Mr. Tesla is callously indifferent to the opinion of his fellows or that he is unduly puffed up over what he has done. On the contrary, he is very human in his desire for approbation, and his mental attitutde concerning his work is that he has only made a beginning in the field of electrical discoveries. But he realizes that the real results of his labors are not in any sense dependent upon the estimation in which he is held personally, that the test of time alone can determine the value of his discoveries and that his best course is to go ahead with his investigations regardless of what any one says of either himself or his many achievements.
Having said this much, it is only fair to say that Tesla is possessed of a most luxuriant imagination and that some of his outgivings to his friends of the press may have seemed ill advised to certain persons because of apparent extravagance. Tesla is completely wrapped up in the study of the mystic current. He firmly believes that in its complete subjection by man lies the solution of most problems with which humanity is vexed.

Mr. Tesla does not say this remarkable development is likely soon to take place, nor does he believe the world is yet ready for it. He holds, indeed, that down to the present time electrical discovery and development have been almost too rapid, and that in contemporary human conditions there is great danger that more rapid development would tend to increase rather than decrease existing inequalities. For this reason he tells his friends he does not attempt to put his more daring electrical conceptions into concrete form or to realize the utmost from his more sensational electrical discoveries. He explained the principles of wireless telegraphy in print and on the lecture platform several years ago, besides experimentally proving the correctness of his notions satisfactorily to himself, but he has never set out to prove

But those who believe Tesla wholly visionary and deem none of his work practical fly very wide of the truth. It is true that the cherished "oscillator," of which he is known to expect almost unthinkable things, and half a dozen other inventions and discoveries of which he has from time to time allowed the world to get a glimpse have not yet been made practical, but it is also true that the trolley cars of today, which have revolutionized the methods of intramural transit in every city and sizable town in the United States, could not be operated profitably had he not discovered what electricians term the "rotating field."

His big income is mainly spent by Mr. Tesla in making such experiments and investigations as he thinks will tend not to the immediate increase of electricity's practical utilization, but such as in his opinion will help most in the mystic current's ultimate subjection. This is the work he likes most to do. It is indeed the only work he would ever turn his hand to were it not necessary to have an income to carry this on. It may be that he overestimates both the ultimate possibilities of electrical development and his own power in this regard, but of his sincerity in the premises there is not the slightest doubt in the minds of those who know him well.

In closing this letter it is only right to say that it has been written entirely without Mr. Tesla's knowledge and with the full understanding that he is more likely to resent it than otherwise if it seems in any way to assume to defend him or his work.
