Tributes have flowed in on social media for Hans Rosling, who died aged 68 on Tuesday. Rosling, a visionary statistician and educator, had a gift for analysing complex development data on issues such as global health, population and climate change, and presenting it in a compelling, accessible way. His aim was to present a “fact-based worldview”, challenging assumptions on development with his forensic examination of figures.

Ulrika Modéer, the Swedish secretary of state for development cooperation, paid her respects to Rosling on Twitter.

Historian Greg Jenner praised Rosling’s “ingenious and impactful” insight into data.

David Nabarro, formerly the UN’s special envoy for Ebola and now among the final three contenders to lead the World Health Organisation, liaised with Rosling in Monrovia when the statistician was working with the Liberian government on its emergency response to the disease in 2014. He recalled that Rosling “changed the way we all conceive of people’s health”.
