Ernest Lawrence Thayer

Ernest Lawrence Thayer (; August 14, 1863 – August 21, 1940) was an American writer and poet who wrote the poem "Casey" (or "Casey at the Bat"), 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".
