This is an amazing artifact of scientific education from 1944, complete with images of retro radio equipment, hospital radium rays and one of the first commercially available television set. Putting together a chart like this can be as much of an undertaking as publishing a book. It's an under-appreciated art form, and sometimes takes a coordinated team of editors, designers and consultants years to produce a final product. The driving force behind its creation in the late 1930s was Dwight Barr. He spent two years of his life designing and editing it, with the project at times taking over part of his house. Once published, nearly every major university and scientific institution bought a copy. Each section of the spectrum corresponds to a color-coded section in the bottom area. You can learn all about the properties, uses and effects of each type of electromagnetic wave. It covers everything from simple diffraction to the effects of cosmic rays.Glimpses of it can often be seen in the backgrounds of educational films and even hollywood films like Steve Martin's The Man With Two Brains and Disney's The Computer Wore Tennis Shoes.
