Terry Pratchett has died at his home surrounded by his loved ones and cat at age 66 after a public and bravely frank battle with early-onset Alzheimer's disease. The author of the popular and beloved Discworld series was known for his honest and dryly humorous writing style, and an observational wit that was considered one of the sharpest in the world. His final tweets are a fitting end to such an illustrious career. 






For those who aren't familiar with his books, "Death" was actually a recurring character within his writings, often appearing alongside his pale horse "Binky".  A fundraising page has been set up in his memory to help fund research for the treatment of Alzheimer's disease and other age-related illnesses.
