Preface to My Inventions PDF

I. My Early Life

The progressive development of man is vitally dependent on invention.

It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs.

This is the difficult task of the inventor who is often misunderstood and unrewarded.

But he finds ample compensation in the pleasing exercises of his powers and in the knowledge of being one of that exceptionally privileged class without whom the race would have long ago perished in the bitter struggle against pitiless elements….. continued in this book

II. My First Efforts At Invention

I shall dwell briefly on these extraordinary experiences, on account of their possible interest to students of psychology and physiology and also because this period of agony was of the greatest consequence on my mental development and subsequent labors.

But it is indispensable to first relate the circumstances and conditions which preceded them and in which might be found their partial explanation….. continued in this book

III. My Later Endeavors The Discovery of the Rotating Magnetic Field

At the age of ten, I entered the Real Gymnasium which was a new and fairly well equipt institution.

In the department of physics were various models of classical scientific apparatus, electrical and mechanical.

The demonstrations and experiments performed from time to time by the instructors fascinated me and were undoubtedly a powerful incentive to invention.

I was also passionately fond of mathematical studies and often won the professor’s praise for rapid calculation.

This was due to my acquired facility of visualizing the figures and performing the operations, not in the usual intuitive manner, but as in actual life.

Up to a certain degree of complexity, it was absolutely the same to me whether I wrote the symbols on the board or conjured them before my mental vision.

But freehand drawing, to which many hours of the course were devoted, was an annoyance I could not endure.

This was rather remarkable as most of the members of the family excelled in it.

Perhaps my aversion was simply due to the predilection I found in undisturbed thought.

Had it not been for a few exceptionally stupid boys, who could not do anything at all, my record would have been the worst.

It was a serious handicap as under the then existing educational regime, drawing being obligatory,

This deficiency threatened to spoil my whole career and my father had considerable trouble in railroading me from one class to another. ….. continued in this book

IV. The Discovery of the Tesla Coil and Transformer

For a while, I gave myself up entirely to the intense enjoyment of picturing machines and devising new forms.

It was a mental state of happiness about as complete as I have ever known in life. Ideas came in an uninterrupted stream and the only difficulty I had was to hold them fast.

The pieces of apparatus I conceived were to me absolutely real and tangible in every detail, even to the minute marks and signs of wear.

I delighted in imagining the motors constantly running, for in this way they presented to mind’s eye a more fascinating sight.

When natural inclination develops into a passionate desire, one advances towards his goal in seven-league boots.

In less than two months I evolved virtually all the types of motors and modifications of the system which are now identified with my name.

It was, perhaps, providential that the necessities of existence commanded a temporary halt to this consuming activity of the mind.

I came to Budapest prompted by a premature report concerning the telephone enterprise and, as the irony of fate willed it,

I had to accept a position as draftsman in the Central Telegraph Office of the Hungarian Government at a salary which I deem it my privilege not to disclose! Fortunately,

I soon won the interest of the Inspector-in-Chief and was thereafter employed on calculations, designs, and estimates in connection with new installations, until the Telephone Exchange was started, when I took charge of the same.

The knowledge and practical experience I gained in the course of this work were most valuable and the employment gave me ample opportunities for the exercise of my inventive faculties.

I made several improvements in the Central Station apparatus and perfected a telephone repeater or amplifier which was never patented or publicly described but would be creditable to me even today.

In recognition of my efficient assistance the organizer of the undertaking,

Mr. Puskas, upon disposing of his business in Budapest, offered me a position in Paris which I gladly accepted.. ….. continued in this book

V. The Magnifying Transmitter

As I review the events of my past life I realize how subtle are the influences that shape our destinies. An incident of my youth may serve to illustrate.

One winter’s day I managed to climb a steep mountain, in company with other boys.

The snow was quite deep and a warm southerly wind made it just suitable for our purpose.

We amused ourselves by throwing balls that would roll down a certain distance, gathering more or less snow, and we tried to outdo one another in this exciting sport.

Suddenly a ball was seen to go beyond the limit, swelling to enormous proportions until it became as big as a house and plunged thundering into the valley below with a force that made the ground tremble.

I looked on spellbound, incapable of understanding what had happened. For weeks afterward the picture of the avalanche was before my eyes and I wondered how anything so small could grow to such an immense size.

Ever since that time, the magnification of feeble actions fascinated me, and when, years later,

I took up the experimental study of mechanical and electrical resonance, I was keenly interested from the very start.

Possibly, had it not been for that early powerful impression, I might not have followed up the little spark I obtained with my coil and never developed my best invention,

the true history of which I’ll tell here for the first time….. continued in this book

VI. The Art of Telautomatics

No subject to which I have ever devoted myself has called for such concentration of mind and strained to so dangerous a degree the finest fibers of my brain as the system of which the Magnifying Transmitter is the foundation.

I put all the intensity and vigor of youth in the development of the rotating field discoveries, but those early labors were of a different character.

Although strenuous in the extreme, they did not involve that keen and exhausting discernment which had to be exercised in attacking the many puzzling problems of the wireless.

Despite my rare physical endurance at that period the abused nerves finally rebelled and I suffered a complete collapse, just as the consummation of the long and difficult task was almost in sight….. continued in this book
