Hans Rosling: A short, easy-to-read biography

Hans Rosling (27 July 1948 – 7 February 2017) was a Swedish doctor, teacher, and public speaker who used data to explain how the world is changing. He was a professor of international health at Karolinska Institute and co‑founded the Gapminder Foundation, which created tools to show global statistics in clear, moving graphics.

Early life and education
- Born in Uppsala, Sweden.
- Studied statistics and medicine at Uppsala University (1967–1974) and public health at St. John’s Medical College in Bangalore, India (1972).
- Became a licensed physician in 1976.
- He was dyslexic, which made his achievements even more remarkable.

Career and achievements
- Worked in Mozambique (1979–1981) and investigated an outbreak called konzo, earning a PhD from Uppsala University in 1986.
- Co-founded Gapminder with his son Ola and daughter-in-law Anna Rosling Rönnlund. Gapminder created Trendalyzer, software that turns data into animated visuals to help people understand world development.
- Google bought Trendalyzer in 2007 to expand access to public statistics.
- Famous for engaging, data-driven talks and TV projects, including The Joy of Stats (BBC Four, 2010), Don’t Panic — The Truth about Population (BBC Two, 2013), and Don’t Panic: How to End Poverty in 15 Years (2015).

Factfulness and legacy
- After his death, his book Factfulness, coauthored with Ola Rosling and Anna Rosling Rönnlund, was published and became a global bestseller. It argues that the world is often better than people think and offers a practical way to understand global development.
- Rosling promoted a “possibilist” view: acknowledge progress and work to keep making things better, rather than simply hoping or fearing.
- He also supported refugee aid efforts and worked with UN agencies to help those in need.

Health and death
- Rosling faced health challenges from a young age, including hepatitis C and liver problems. In 2016 he was diagnosed with pancreatic cancer and died in 2017 in Uppsala, Sweden.

Public perception
- Many see Rosling as one of the most influential figures in global health and data visualization. Some critics say his optimistic outlook downplays ongoing problems, but his work encouraged people to rely on facts and evidence to understand the world and to take action to improve it.
