"[Lloyd] Richards, a luminary who, with the original production of A Raisin in the Sun, became the first Black director to stage a Broadway play, emphasized dramaturgy."
— Abigail Aguirre, Vogue, January 2021

"As we walked homeward across the fields, the sun dropped and lay like a great golden globe in the low west. While it hung there, the moon rose in the east, as big as a cart-wheel, pale silver and streaked with rose colour, thin as a bubble or a ghost-moon. For five, perhaps ten minutes, the two luminaries confronted each other across the level land, resting on opposite edges of the world."
— Willa Cather, My Antonia, 1918
