Ernest Lawrence Thayer was an American writer and poet who wrote the poem "Casey", which is "the single most famous baseball poem ever written" according to the Baseball Almanac, and "the nation’s best-known piece of comic verse—a ballad that began a native legend as colorful and permanent as that of Johnny Appleseed or Paul Bunyan."
