Joseph Juran 1904 – 2008
I haven't run the numbers, but it's probably fair to say that Juran's lifespan was far beyond +3 standard deviations beyond the mean. His impact and influence on the business world, quality, Lean, and Six Sigma was certainly well off the positive end of the bell curve.
It sounds like he never retired since he found so much joy in his work. Juran (to the left in the picture with Dr. Deming) is survived by a wife of 81 years, also living far beyond the mean. The NY Times obituary and the wikipedia page tells the story of a pretty amazing life. Rest in peace.
