Pratchett was the author of more than 70 books and had won numerous awards for his work, including a Los Angeles Times Book Prize in 2008.
The Times honored Pratchett for his young adult novel "Nation." The author filmed his acceptance speech at his home wearing casual pants and a black T-shirt, with his cat standing on his desk during the remarks and charming those gathered in Los Angeles.
Pratchett is survived by his wife, Lyn, and their daughter, Rhianna.
The statement from his publisher noted that his cat was also with him at the end, "sleeping on his bed," as Pratchett was surrounded by his family.
