Chickering & Sons was an American piano manufacturer located in Boston, Massachusetts, known for producing award-winning instruments of superb quality and design. The company was founded in 1823 by Jonas Chickering and James Stewart, but the partnership dissolved four years later. By 1830, Jonas Chickering became partners with John Mackay, manufacturing pianos as "Chickering & Company" and later "Chickering & Mackay’s" until the senior Mackay died in 1841, and reorganized as "Chickering & Sons" in 1853. Chickering pianos continued to be made until 1983.
