Decades and even centuries ago, great personalities laid the foundation of the products and services Q-DAS provides. Their ground-breaking ideas and achievements still shape our world today. Do you know these persons?

1. He formulated a specific case of the theorem that bears his name; this theorem provided a solution to a problem of inverse probability. Even though he published his essay in the 18^th century, his theorem was only applied in various industries and research at the end of the 20^th century.

• Jacob Bernoulli
• Thomas Bayes
• Walter Andrew Shewhart
   

2. He had a strong influence on the application of statistical methods in operative quality management; he is most famous for his graphical method applied to control processes online.

• Blaise Pascal
• Thomas Bayes
• Walter Andrew Shewhart
   

3. To help his father calculate taxes, he started some pioneering work on calculating machines. His mechanical calculator and thoughts behind it laid the foundation of modern computer science.

• Blaise Pascal
• Ronald Aylmer Fisher
• Walter Andrew Shewhart
   

4. He was the one who provided us with statistical design of experiments (DoE) and the analysis of variance (ANOVA) – still today, both aspects are substantial parts of statistical process analysis.

• Blaise Pascal
• Johann Carl Friedrich Gauß
• Ronald Aylmer Fisher
   

5. Before the Euro was introduced, his portrait was featured on a German banknote. We owe him the normal distribution curve and the associated mathematical formula.

• Johann Carl Friedrich Gauß
• Ronald Aylmer Fisher
• Siméon Denis Poisson
   

6. At the tender age of 25, he became full professor in mathematics at the École Polytechnique in Paris. He developed several processes as a type of distribution that bears his name. His distribution type is of high practical relevance in quality management.

• Johann Carl Friedrich Gauß
• Karl Pearson
• Siméon Denis Poisson
   

7. He was the first to apply statistics to biology, especially to inheritance. He also established the scientific journal “Biometrika“ and founded the Anglo-Saxon school of biometrics.

• Jacob Bernoulli
• Karl Pearson
• Siméon Denis Poisson
   

8. He is known for his numerous contributions to calculus and was one of the founders of the calculus of variations. His most important contribution was the first version of the law of large numbers for statistical modelling. It is required to describe machines, production equipment, processes and measurement systems.

• Jacob Bernoulli
• Karl Pearson
• Thomas Bayes
   

We know what we owe to these personalities. This is the reason why each conference room of the Q-DAS headquarters in Weinheim bears the name of one of the persons named above.
