In 1993, Rosling helped co-found Médecines sans Frontières in Sweden. He also served as an adviser to the World Health Organization and UNICEF. He was professor of international health at Karolinska Institutet in Stockholm and the author of “Global Health: An Introductory Textbook.” In 2012, he appeared as one of “Time’s 100 Most Influential People.” Rosling was an elected member of both the Swedish Academy of Engineering Sciences and the Swedish Academy of Sciences and was the recipient of multiple honorary doctorates. He was also awarded the Royal Patron’s Medal from London’s Royal Geographical Society. Rosling died in 2017 at the age of 68 after a year-long battle with pancreatic cancer.
