Bennett's masterpiece, The Old Wives' Tale (1908), chronicles the contrasting lives of two sisters over several decades and remains a landmark of English realism. His Clayhanger trilogy—Clayhanger (1910), Hilda Lessways (1911), and These Twain (1916)—further explores industrial life and social change in the Potteries. Other notable novels include Anna of the Five Towns (1902), the comic The Card (1911), and Riceyman Steps (1923), winner of the James Tait Black Memorial Prize.
Beyond fiction, Bennett achieved enormous influence with self-help works such as How to Live on 24 Hours a Day (1908), which offered practical advice on time management. He also wrote successful plays and literary criticism. Though his reputation declined after his death, Bennett's detailed realism and sharp social observation have earned renewed critical appreciation in recent decades.
