Historical introduction to EMF health effects

The history is traced from the knowledge of the ancient Greeks, through the effects of "static electricity" in the eighteenth century, to the nineteenth century which saw rapid developments in electrotechnology and also in medical uses of electricity and magnetism. Through the nineteenth century, attention began to shift from the applications of static electricity to those of galvanic current. The beginning of the twentieth century marked a period of intense interest of physiologists into the modes of interaction of RF energy with biological systems. Public controversy arose over the issue of microwave oven safety. Finally other questions of cancer in relation to ELF bioeffects and power-frequency magnetic and electric fields are addressed.
