Sandburg earned Pulitzer Prizes for his collection "The Complete Poems of Carl Sandburg", "Corn Huskers", and for his biography of Abraham Lincoln (""). Sandburg is also remembered by generations of children for his "Rootabaga Stories" and "Rootabaga Pigeons", a series of whimsical, sometimes melancholy stories he originally created for his own daughters. "The Rootabaga Stories" were born of Sandburg's desire for "American fairy tales" to match American childhood. He felt that the European stories involving royalty and knights were inappropriate, and so populated his stories with skyscrapers, trains, corn fairies and the "Five Marvelous Pretzels".
