Dr. Hans Rosling is one of my presentation heroes; he's been featured or mentioned in all my books and several times on presentationzen.com over the years. If there is a Jedi Master of presenting data clearly, visually, and simply, then it is Hans. He proves time and time again, that data are not dull—and when you are trying to change the world, there is no excuse for boring presentations. Most people are aware of Dr. Rosling through his popular TED Talks, but just in case you've never seen him present, below is a nice 5-minute piece he did on CNN's Fareed Zakaria GPS. At TED.com you'll find many video presentations and articles on Hans Rosling.

Documentary: Rosling's World
One of the videos you will find on gapminder.org is this documentary on Hans Rosling. It is fantastic and well worth your time (about an hour). It is in Swedish so do not forget to click on CC in Youtube for the English subtitles if you need them. Dr. Rosling is an inspiring figure who is doing his own bit to change the world in a big way. His story is one more people need to hear. And Gapminder.org is an invaluable resource for educators. Loads of videos, and downloads, and tons of indicators displayed in Gapminder World.
