Statistical quality control started with Walter Shewart (http://www.asq.org/about-asq/who-we-are/bio_shewhart.html) in the research arm of Western Electric, known later as Bell Labs, and currently as Lucent Technologies. The use of statistical quality control was later popularized by W.E. Deming (http://www.asq.org/about-asq/who-we-are/bio_deming.html). Read about the history of the development of statistical quality control by these two quality pioneers and briefly summarize of what you learned.
