The earliest observations on the reactions of high-frequency electromagnetic currents upon the human organism were made by Jacques Arsene dArsonval.[1][2][3] The field was pioneered in 1907 by German physician Karl Franz Nagelschmidt, who coined the term diathermy from the Greek words dia and θέρμη therma, literally meaning "heating through" (adj., diather´mal, diather´mic).
