Hans Rosling

Hans Rosling (born 27 July 1948) is a Swedish medical doctor, academic, statistician and public speaker. He is the Professor of International Health at Karolinska Institutet and co-founder and chairman of the Gapminder Foundation, which developed the Trendalyzer software system.

Biography

Rosling was born in Uppsala, Sweden. From 1967 to 1974 Rosling studied statistics and medicine at Uppsala University, and in 1972 he studied public health at St. John's Medical College, Bangalore, India. He became a licensed physician in 1976 and from 1979 to 1981 he served as District Medical Officer in Nacala in northern Mozambique.

On 21 August 1981, Rosling discovered an outbreak of konzo, a paralytic disease, and the investigations that followed earned him a Ph.D. degree at Uppsala University in 1986. He spent two decades studying outbreaks of this disease in remote rural areas across Africa and supervised more than ten Ph.D. students. Outbreaks occur among hunger-stricken rural populations in Africa where a diet dominated by insufficiently processed cassava results in simultaneous malnutrition and high dietary cyanide intake.

Starting in 1987, Gates was included in the Forbes list of the world's wealthiest people and was the wealthiest from 1995 to 2007, again in 2009, and has been since 2014. Between 2009 and 2014, his wealth doubled from US$40 billion to more than US$82 billion. Between 2013 and 2014, his wealth increased by US$15 billion.

Gates is one of the best-known entrepreneurs of the personal computer revolution. Gates has been criticized for his business tactics, which have been considered anti-competitive, an opinion which has in some cases been upheld by numerous court rulings. Later in his career Gates pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, established in 2000.
