Ella Wheeler Wilcox (November 5, 1850 – October 30, 1919) was a poet best known for the collection Poems of Passion and for "Solitude," which opens with the line, "Laugh, and the world laughs with you; weep, and you weep alone." She's also sometimes cited in lists of authors of bad poetry, but we think she'd agree that that's only by the haters.

William Butler Yeats (13 June 1865 – 28 January 1939) was a poet, playwright, fiction writer, and one of the most well regarded authors of the 20th century. A senator in the Irish Free State and winner of the Nobel Prize for Literature, he wrote "The Second Coming," "Easter 1916," and "Sailing to Byzantium," all of which are considered masterpieces in the English language.
