Who wrote Anne of Green Gables, the story set in Prince Edward Island?

No province is smaller than Prince Edward Island, usually written P.E.I. Its beaches draw visitors, its soil is red, and farming counts for a lot there - potatoes most of all. P.E.I. is known as the birthplace of Confederation. The Confederation Bridge ties the island to mainland Canada, and among the world's continuous multispan bridges it is one of the longest. Lucy Maud Montgomery set Anne of Green Gables on the island. That much-loved tale tells of a little orphan girl with red hair, and of the adventures she has.
