12 янв 1931 г. - In 1931, Walter Shewhart published "Economic Control of Quality of Manufactured Products" (economic Control of the quality of products manufactured), in which the basic principles of the control of the quality, on the basis of statistical methods, arise focusing on the use of Control boxes. Thus becoming the father of modern quality Control (though some authors have given this paternity to Deming, must consider that Deming studies were initially based on the Shewhart)
