An early American writer on invention and electrical science, he helped explain new technologies at a moment when X-rays and modern patent culture were just taking shape. His books mix practical advice for inventors with clear curiosity about the fast-moving discoveries of the late nineteenth century.

by Edward P. (Edward Pruden) Thompson
Edward Pruden Thompson was an American electrical engineer and patent attorney associated with New York. He wrote practical and technical books at a time when invention, electricity, and industrial research were reshaping everyday life.
His best-known works include How to Make Inventions; or, Inventing as a Science and an Art (1891) and Roentgen Rays and Phenomena of the Anode and Cathode (1896). The latter was recognized as one of the earliest American books on X-rays, gathering and explaining important research soon after those discoveries caught public attention.
Available records identify him as having lived from 1856 to 1942. While detailed biographical information appears to be limited, his surviving books show a writer interested in making complex scientific and technical ideas useful to working inventors and curious readers.
