    I hope someone won’t mind helping me. I would like know who is the first person to invent statistical quality control? Was it Walter Shewhart? Did anyone else use the statistics to measure quality before him, or did he become the first person when he used his control charts?Petrus




    I thought it was Al Gore.


    Al Gore invented the Internet…..sheeesh………


    Walter A. Shewhart developed (I wouldn’t use the word “invented”) the control chart in the 1920’s at Bell Laboratories.
    Dr. W. Edwards Deming brought (or tried to bring) Shewhart’s techniques to manufacturing processes in the late 1930’s and 1940’s.
    I’m not sure if it would be possible to trace the beginnings of the “use of statistics to measure quality” through world history.


    Try Florence Nightingale. She used statistics to monitor infections. The actual SPC control chart would be Shewhart as far as I know.

    Some will argue that the both the Myans and Egyptians used crude forms of Statistics to help organize and track workers and schedules


    I would give the credit to Shewhart.  It seems that Deming often mistakingly gets credit for what Shewhart developed.  Deming merely popularized it as a tool for manufacturing.


    And he invented the fictional “Global Warming”…just after he won the Whopper eating contest. And you think George W. is a loser……


    Don’t forget Dr. Joseph Juran’s contribution either.
    But then we’ll probably shortly hear Stan saying he invented it; you do know he’s the one who has trained the only true 50 MBB’s in the world.


    My understanding is Shewhart only invented statistical control charts. The real breakthrough came when someone combined the normal distribution with a set of specification to denote outliers as defects. But who did it is anyone’s guess …
