Hello, Dolly! is a 1964 musical based on Thornton Wilder's 1938 farce The Merchant of Yonkers, which Wilder revised and retitled The Matchmaker in 1955. The musical follows the story of Dolly Gallagher Levi, a strong-willed matchmaker, as she travels to Yonkers, New York, to find a match for the miserly "well-known unmarried half-a-millionaire" Horace Vandergelder.
