 The Computer Science terms Big-Endian and Little-Endian were introduced by Danny Cohen [#CohenDanny]_ in 1980. The key term *endian* has its roots in the novel Gulliver’s Travels [#GulliversTravels]_ by Jonathan Swift [#SwiftJonathan]_ where within a war occurs between two factions who are fighting over which end of a boiled egg should be opened for eating. The big end or the little end. Unsurprisingly, the same said book was the inspiration for the naming of the `Gulliver </~https://github.com/sandialabs/gulliver>`_ library.
