Michael Sohlman, the executive director of the Nobel Foundation, talks to Riz Khan
On Tuesday Riz speaks with Michael Sohlman, the executive director of the Nobel Foundation. Since 1901 Nobel prizes have been awarded for human achievement in physics, chemistry, medicine, peace and literature. In 1968 a sixth prize was inaugurated for economics.

The prizes are coveted for more than the diploma, medal and cash award (currently estimated at close to $1.5m). They seem to represent a large 'thank you' from humankind for trailblazing scientists, writers and politicians.

But the history of the Nobel Prize has not always been a smooth one.
