A book that argues Elizabethan poet John Donne should rank alongside William Shakespeare as a literary genius has won Britain’s leading nonfiction book award.

British writer Katherine Rundell’s biography “Super-infinite: The Transformations of John Donne” was named winner of the 50,000 pound ($59,000) Baillie Gifford Prize at a ceremony in London.

Rundell said she will give her prize money away to a refugee group and a climate-change charity — inspired by Donne’s most famous lines: “No man is an island ... any man’s death diminishes me, because I am involved in mankind.”
