"Gadsby: a story of over 50,000 words without using the letter 'E'" by Ernest Vincent Wright is a novel published in 1939. This lipogram deliberately avoids using E, the most common letter in English. The story follows John Gadsby as he rallies youth to revitalize the declining city of Branton Hills. Wright tied down his typewriter's E key to prevent accidental usage while writing. Once obscure and vanity-published, the novel has become a cult favorite among constrained writing enthusiasts and rare book collectors.
