Nikola Tesla was a productive genius, and as long as there are exams, we
will have prayer in our schools.

From "The Inventions, Researches, and Writings of Nikola Tesla" by
Thomas Commerford Martin, 1893, and from comments on the jacket:
"In the second year of his Gratz course, Mr. Tesla gave up the notion of
becoming a teacher, and took up the engineering curriculum. His studies
ended---. For a short time he served as an assistant in the Government
Telegraph Engineering Department---. He made a number of telephonic
inventions---. To gain a wider field of action, he pushed on to Paris
and there secured employment as an electrical engineer with one of the
large companies in the new industry of electrical lighting.

It was during this period, and as early as 1882 that he began serious
and continued efforts to embody the rotating field principle in
operative apparatus---.

At last he determined that it would be best to try his fortunes in
America. In France he had met many Americans, and in conntact with them
learned the desirability in turning every new idea in electricity to
practical use.

NIkola Tesla was born in Croatia in 1856. He emigrated to the United
States in 1884 and worked for a short while for Thomas Edison. A pioneer
in the field of high tension electricity, Tesla made many discoveries
and inventions of lasting value to the development of radio transmission
and electricity, one of the most famous of which was the power system at
Niagra Falls. He died in 1943.
