New Catechism of Electricity

Nehemiah Hawkins

"The great forces of the world are invisible and impalpable; we cannot grasp or handle them; and though they are real enough they have the appearance of being very unreal. Electricity and Gravity are as subtle as they are mighty; they elude the eye and hand of the most skillful philosopher. In view of this, it is well for the average man not to try to fathom, too deeply, the science of either; neither Edison or Tesla have done that yet."

Before Nikola Tesla and alternating current was Thomas Edison and direct current. New Catechism of Electricity was written in 1896 and dedicated to “Thomas A. Edison of Llewellyn Park, N.J.,” when Edison was still alive and actively inventing at the age of 49. This is the 1903 printing of the book. Author Nehemiah Hawkins often wrote under the name Theodore Audel for Theodore Audel & Company of New York. The many Audel books that were to follow utilized multitudes of illustrations (this book has some 300) to teach technical subjects to generations of craftsmen and engineers for over 100 years.
