Stevens-Duryea was an American automotive manufacturer that was founded in 1901. Based in Massachusetts, Stevens-Duryea began building simple, two-cylinder powered cars, before eventually growing operations that included building a range of inline four and inline six engines. Operations continued until 1915, when the company had financial problems and had to end production. A few years after, in 1923, the company tried to restart operations, with limited success until Stevens-Duryea ended for good in 1927.
