Sigrid Rausing

Kirsty Young's castaway is the philanthropist and publisher Sigrid Rausing.

Founder of one of the UK's largest philanthropic foundations, her trust has given away around £230m to human rights causes since it began.

Brought up in Sweden, she is currently the publisher of Granta Books and the editor of Granta Magazine and her work spotting and developing new writers stems from her lifelong love of literature.

As the granddaughter of Ruben Rausing, who founded food packaging company Tetra Pak, she is a member of one of Britain's richest families. Her interest in human rights was sparked as a child by a love of animals and hearing her parents talk about the Holocaust.
