Saint Leibowitz

Isaac Edward Leibowitz is married to a woman named Emily. He lives during a nuclear war in the United States, referred to as “the flame deluge.” Leibowitz is a technician and drafts a blueprint for a transistorized control system. The blueprint is replicated centuries later by Brother Francis Gerard of Utah, a monk. Leibowitz is a hero to the monks. A statue of Leibowitz stands in the monastery which is named after him in his honor. The monks refer to him as Beatus ('Blessed') Leibowitz prior to the canticle ceremony, and he is called 'Saint Leibowitz' after it (Brians 2007, 3).

After the death of his wife Emily, he takes vows to become a priest. He establishes a religious community dedicated to preserving history for generations to come. They smuggle books for preservation and act as "memorizers" who remember the books in case the books are destroyed. Leibowitz feels it important to preserve documents so mankind in the future will be able to educate themselves about their heritage. The world is going through a simplification. All knowledge, especially written words, is deemed evil. He is considered a martyr, caught and strangled while smuggling books. The mob destroys documents and books hidden in kegs so only a few books and documents remain.

Saint Isaac Edward Leibowitz is a pioneer archivist. He is revered, especially by the monks. Centuries after his death, other monks continue the work of preserving written documents. Saint Leibowitz's foresight prevents future generations from being deprived of their heritage.
