There is not much to be added to all the articles on Hans Rosling’s death...
You can find more information about his life and work in his wiki-article. And his daughter-in-law and son probably put it best by saying: "Hans is no longer alive, but he will always be with us and his dream of a fact-based worldview, we will never let die!"
So we only add that are deeply sad that he is gone.
And i personally that i am thankful for inspiring me to enter the fascinating field of data (analysis, visualization and journalism).
