Nessler conducted his first experiments on his wife, Katharina Laible. The first two attempts resulted in completely burning her hair off and some scalp burns, but the method was improved and his electric permanent wave machine was used in London in 1909 on the long hair of the time.
Karl Ludwig Nessler was born on 2 May 1872 in Todtnau. He was the son of Rosina (née Laitner) and Bartholomäus Nessler, a cobbler in Todtnau, a small town located high in the Black Forest, just beneath the Feldberg. He reportedly conceived the idea of a permanent wave early on.
A part of the field that survived was diathermy, the application of high frequency current to heat body tissue, pioneered by German physician Karl Nagelschmidt in 1907. [ 111 ] [ 118 ] During the 1920s "long wave" (0.5~2 MHz) Tesla coil spark diathermy machines were used, in which the current was applied to the body by electrodes.

The first half of the 700-page book is a history of the study of electricity. It is parted into ten periods, starting with early experiments "prior to those of Mr. Hawkesbee", finishing with variable experiments and discoveries made after Franklin's own experiments.
The spectrography experiments enabled a better understanding and subsequently the first glimpses of practical application. The mid 20th century saw experiments with EWM as a light source and for the production of nanoparticles in aluminum, uranium and plutonium wires.
"Egg of Columbus" demonstration at the 1893 Columbian Exposition. Tesla's Egg of Columbus was a device exhibited in the Westinghouse Electric display at the 1893 Chicago World's Columbian Exposition to explain the rotating magnetic field that drove the new alternating current induction motors designed by inventor Nikola Tesla by using that magnetic field to spin a copper egg on end.
The Tesla Experimental Station [1] was a laboratory in Colorado Springs, Colorado, USA built in 1899 by inventor Nikola Tesla and for his study of the use of high-voltage, high-frequency electricity in wireless power transmission. Tesla used it for only one year, until 1900, and it was torn down in 1904 to pay his outstanding debts.
