Kaoru Ishikawa is recognized by many as the "master" and father of Quality.  If not on a global scale than certainly in his native land of Japan.  Kaoru Ishikawa was most noted for the development of the Ishikawa, Cause and Effect or Fishbone diagram, however his impact on quality spread much further than just cause and effect.

     Shewhart was the first honorary member of the American Society of Quality. He brought together the disciplines of statistics, engineering, and economics which eventually earned him the right to be known as the father of quality. 

   In 1945 many quality associations began forming around the world.  The benefits and passion surrounding quality and industrial activities were gaining momentum.  Almost 40 years earlier, Romania would see the face of one, Joseph Juran.  As one of six children Mr. Juran grew up with two sisters who shared his passion for learning.  Juran would live first in România and then in Humorului for only a short time before his family would settle in Minneapolis.  Here Juran would earn his High School degree from Minneapolis South High School in 1920.

  There is not just one thing that Dr. Akao can be noted for.  A true advocate of continuous improvement is the best way to sum up Dr. Akao.  As the 24'th honorary member of the ASQ, Dr. Akao led many great projects with his development of Quality Function Deployment.  Along with QFD, Dr. Akao developed several other methodologies that became normal practices in Japan.  While methodologies were not foreign to Dr. Akao he was often found advocating strategic initiatives like Hoshin Kanri worldwide.  

​  Frederick Taylor was a mechanical engineer who pioneered the principles of scientific management.  He was passionate about improving efficiency during the late 1800's through the early 1900's.  Frederick's efforts in applying engineering principles to factory environments were some of the first to later develop into what we know today as industrial engineering.  
  Taylor passed the entrance exam for Harvard but did not attend Harvard.  Instead of pursuing extended education he chose to become an apprentice patternmaker and a machinist at Enterprise Hydraulic Works in Philadelphia.  Eventually Mr. Taylor would complete his apprenticeship and move on to climb the ladder of the Midvale Steel Works.  It was here that Fredericks talents would eventually lead him to hold such positions as chief engineer.

  Philip Bayard "Phil" Crosby, (June 18, 1926 – August 18, 2001) was a businessman and author who contributed to management, theory and advocated quality in many different ways.  Crosby initiated the Zero Defects program at the Martin Company. As the quality control manager of the Pershing missile program, Crosby was credited with a 25 percent reduction in the overall rejection rate and a 30 percent reduction in scrap costs.

  Eli Whitney was a famous American inventor in the late 1700’s and early 1800’s.  Most people know Mr. Whitney for his invention of the cotton gin.  He was born in 1765 and attended Yale University.  While his cotton gin invention was in fact revolutionary many people attempted to steal the idea which ultimately led to Mr. Whitney changing his focus to guns and ammunition.  At this time muskets required a great deal of manual labor and time to build.  To reduce the amount of time and complexity associated with building a musket Mr. Whitney began building interchangeable parts which certainly improved the changeover times and reduced the need for workers to setup and re-setup with each musket.  As a result of these interchangeable parts the assembly or assemble to order concept was created.  Along with the design of interchangeable parts Mr. Whitney spent a great deal of time studying the motion of workers and people.  Mr. Whitney’s drive and passion for improving things then lead to what we know today as time and motion studies.  One might guess that even during the industrial revolution many different forms of waste were revealed.

   Professor Jiro Kawakita was a well-known scholar of ethnogeography in Japan. Through his fieldwork and research on the Himalayan Highlanders of Nepal, he has established a distinct methodology in field sciences and revealed the system of the people, culture, way of life and ecology. His achievements are very widely studied and some of the tools he established are still used today, the main one being the affinity diagram which is a tool used within the KJ Method and provides a structured basis for Lean Strategies International LLC’s ©CURE Methodology.
 
   The Following is a great biography borrowed from: Fukuokaprize.  Please note there are not many biographies on this pioneer, master of the Affinity diagram which is widely used in project management today.  If you have any additional information on this Master, please feel free to share, link and comment in the comments section below.  Your name will be cited with the contributions and we would be more than happy to link to a page of yours if you would like.

  

  William Edwards Deming (October 14, 1900 – December 20, 1993) was an American engineer, statistician, professor, author, lecturer, and management consultant. Educated initially as an electrical engineer and later specializing in mathematical physics, he helped develop the sampling techniques still used today by the U.S. Department of Census and the Bureau of Labor Statistics. In his book, The New Economics for Industry, Government, and Education, Deming championed the work of Walter Shewhart who used techniques such as: statistical process control, operational definitions, and what Deming called the "Shewhart Cycle" which would later evolve into the PDCA and PDSA cycles we know today.  
 

  Sir Ronald Aylmer Fisher (17 February 1890 – 29 July 1962), was an author who published as R. A. Fisher, he was also a very accomplished English statistician and biologist. Fisher used mathematics to combine Mendelian genetics and natural selection, which ultimately helped to create the new Darwinist synthesis of evolution known as the modern evolutionary synthesis. He was also a prominent eugenicist in the early part of his life.  Mr. Fisher worked at Rothamsted Research for 14 years beginning in 1919.  It was here where he developed the analysis of variance (ANOVA) which is still used today in six sigma to analyse immense amounts of data.  In Fisher's case it was used to analyse crop experiments.  Later, Mr. Fisher established a reputation as a biostatistician. 

  In 1935 The Design of Experiments was published.  The book was written by the English statistician Ronald Fisher about design of experiments and is considered a foundational work in experimental design.  Among other contributions, the book introduced the concept of the null hypothesis in the context of the lady tasting tea experiment.  Mr. Fisher died in July of 1962 after leaving a powerful legacy full of influence on the world of statistics and six sigma.
