Edwin Abbott Abbott
His oddly redundant name aside, Edwin Abbott Abbott is the coolest comeback kid you've never heard of. In 1884, Abbott published Flatland: A Romance of Many Dimensions, a richly complex social satire about a two-dimensional civilization. The narrator is a lovable 2D square whose world is turned upside down (literally) by a visit from a 3D alien. Flatland was a little too ahead of its time for Victorian society, but Abbot's book gained a cult following about a half-century after his death. The book now has a devoted fan base (including the late, great Carl Sagan) but is remains a very underrated scifi classic.
