Mr Rausing, who is known to his friends as Hans K to differentiate himself from his father, did not enter the business world and instead travelled to India where it is thought he first experimented with drugs. After meeting his wife in a clinic in the United States, the pair moved to London and set up home in Chelsea. They have both donated millions to charity and have lent their support to several organisations that support people struggling with addiction. The couple have worked on a number of charitable initiatives with the Prince of Wales, who once described Mr Rausing as “one very special philanthropist”. Mr Rausing has two sisters Lisbet and Sigrid, who both live in Holland Park, west London. He and Eva have four children, aged between 11 and 17, who attend a private school in East Sussex. Lisbet is a successful historian, while Sigrid is a human rights activist, who funds a number of charitable foundations.
