Edward Casaubon, fictional character, one of the main figures in George Eliot’s masterpiece Middlemarch (1871–72). Casaubon is a pompous and ineffectual middle-aged scholar who marries the heroine, Dorothea Brooke, because he needs an assistant for his work. His “masterwork,” Key to All Mythologies, is stalled and remains unfinished at his death. Eliot contrasts Casaubon with his young, idealistic cousin, Will Ladislaw, who is in love with Dorothea and whom she eventually marries after Casaubon’s death.
