Christopher Dunn has an extensive background as a craftsman, starting his career as an indentured apprentice in his hometown of Manchester, England. Recruited by an aerospace manufacturing company, he immigrated to the United States in 1969. Over the past 49 years, Chris has worked at every level of high-tech manufacturing from machinist, toolmaker, programmer and operator of high-power industrial lasers. Chris's pyramid odyssey began in 1977 after he read Peter Tompkins' book Secrets of the Great Pyramid. His immediate reaction after learning of the Great Pyramid's precision and design characteristics was to consider that this edifice may have had an original purpose that differed from conventional opinion. After further research and study of source material on various theories, Chris concluded that it must have originally been built to provide a highly technical society with energy—in short, it was a very large machine.
