Fantasy author Terry Pratchett left Discworld for a heroic quest to Bradford in order to have his latest honour bestowed upon him.

The 61-year-old hugely-prolific writer – who became Sir Terry in the Queen’s honours this year – swapped his trademark black hat for a cap and gown to receive an honorary Doctor of Letters at the University of Bradford today.

Sir Terry has written 36 comic fantasies set on Discworld – a flat world balanced on the back of four elephants, which in turn ride on a vast turtle swimming through space – as well as a slew of non-Discworld titles, including his children’s novel Nation, which has garnered huge praise and a clutch of awards.

But he is as well-known for his publicly-documented battle with early onset Alzheimer’s disease, and has done a huge amount of work raising the profile of the illness.
