"Chickering & Sons was an American piano manufacturer located in Boston, Massachusetts. 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 & Mackays" until the senior Mackay's death in 1841, and reorganized as "Chickering & Sons" in 1853. Chickering pianos continued to be made until 1983." - (en.wikipedia.org 09.08.2022)
