I'm trying to remember the name of the young colleague who was interested in studying Far Infra-red, and he made a device by winding wire around two spindles and off winding one piece of wire so that every other space was occupied, and then radiation could come in, come off this, and he could diagnose it that way. Well, this infra-red radiation that he was studying was something that was not then popular, nobody had found a good way to use it. But he realized that the patients in the Johns Hopkins hospital had temperature conditions which he could study in this way, without intervening or disturbing the patient. And in the depths of the Depression, he made this idea fly. He ended up as the director of a laboratory associated with the Yale University for the study of body conditions by physical means. But the Depression, that was something that's very hard to describe to people nowadays. There's a Depression day saying; I am a nobody, I come from nowhere, and I live on my nothing a day- part of the song. A neighbor next door killed himself because he didn't see how he was going to support his family.
