“I regarded finding I had a form of Alzheimer's as an insult and decided to do my best to marshal any kind of forces I could against this wretched disease. I have posterior cortical atrophy or PCA. They say, rather ingenuously, that if you have Alzheimer's it's the best form of Alzheimer's to have.”

English author, humorist, and satirist

Sir Terence David John Pratchett was an English author, humorist, and satirist. He is best known for the Discworld series of 41 comic fantasy novels, published between 1983 and 2015, and for Good Omens, the apocalyptic comedy novel he co-wrote with Neil Gaiman in 1990. Pratchett built a long career around fiction that mixes fantasy, satire, and humor. His best-known work, Discworld, spans 41 novels and made him a defining voice in comic fantasy. Good Omens extends that same wit into a story of the apocalypse, written with Neil Gaiman.
