Hidden Figures, the film, has been nominated for three awards at the Oscars and has been a box office hit in the US. It tells the little-known story of a group of African American women and their contribution to the space race in the 50s and 60s. We explore the history of how these women were recruited by Nasa and put to work on complex mathematical tasks – at a time when African Americans and women were far less likely to be employed in such jobs.

A huge hole was left in the world this week with the death of the Swedish statistician Han Rosling. He was a master communicator whose captivating presentations on global development were watched by millions. He had the ear of those with power and influence. His friend Bill Gates said Hans ‘brought data to life and helped the world see the human progress it often overlooked’. In a world that often looks at the bad news coming out of the developing world, Rosling was determined to spread the good news, extended life expectancy, falling rates of disease and infant mortality. He was fighting what he called the ‘post-fact era‘ of global health. He was passionate about global development and before he became famous he lived and worked in Mozambique, India and the Democratic Republic of Congo using data and his skills as a doctor to save lives. Despite ill health he also travelled to Liberia during the Ebola outbreak in 2014 to help gather and consolidate data to help fight the outbreak. On a personal level he was warm, funny and kind and will be greatly missed by a huge number of people.
