Hans Rosling was a Swedish physician, academic, and public speaker. He was a professor of international health at Karolinska Institute and was the co-founder and chairman of the Gapminder Foundation, which developed the Trendalyzer software system. Widely regarded as one of the most influential physicians and geographers in the modern world, he held presentations around the world, including several TED Talks in which he promoted the use of data to explore development issues. His posthumously published book Factfulness, coauthored with his daughter-in-law Anna Rosling Rönnlund and son Ola Rosling, became an international bestseller.
