In England the advent of magnetism seems to have taken place about 1788. In that year one Dr. Mainandus, who had been a pupil first of Mesmer and later of Deslon, arrived in Bristol and gave public lectures on the subject. People of rank and fortune soon came from different cities to be magnetized or to place themselves under his tuition. He afterward established himself in London where he was equally successful in attracting and curing people. So much curiosity was excited by the subject that, about the same time, a man named Holloway gave a course of lectures on animal magnetism in London. Large crowds gathered to hear him at the rate of five guineas for each pupil. Loutherbourg, the painter, and his wife entered upon a similar work. "Such was the infatuation of the people to be witnesses of their strange manipulations," says Mackay, "that at times upwards of three thousand persons crowded round their house at Hammersmith, unable to gain admission. The tickets sold at prices ranging from one to three guineas." Loutherbourg later became a divine healer. From 1789 to 1798 magnetism attracted little or no attention in England. At the latter date a Connecticut Yankee, Benjamin Douglas Perkins, invented "metallic tractors." The Society of Friends built a hospital called the "Perkinean Institute" where all comers might be magnetized free of cost. About 1786 animal magnetism appeared in two different places in Germany--on the upper Rhine and in Bremen. At this time Lavater paid a visit to Bremen and exhibited the magnetizing process to several doctors. Bremen was for a long time a focus of the new doctrine, and thereby was brought into bad repute. About the same time the doctrine spread from Strasburg over the Rhine provinces. Among those active in experiments were Boeckmann of Carlsruhe, Gmelin of Heilbronn, and Pezold of Dresden. Soon it spread all over Germany. In 1789 Selle of Berlin brought forward a series of experiments made at the Charite (Hospital), in which he confirmed some of the alleged phenomena but excluded the supernormal.
