The E. G. Harrington Piano Company was established in 1871 in New York City. The firm quickly gained recognition for building very high quality instruments, and they were producing an estimated 100 pianos a month by 1880. After the turn-of-the-century, the Harrington firm was controlled by the illustrious Hardman, Peck & Company. The Harrington factory built pianos under the names of Harrington, Standard, Hensel, and the Autotone player piano line.

Hardman – Peck and all subsidiaries (including Harrington) were purchased by industrial giant Aeolian during the Great Depression era, and they continued to build Harrington pianos until the 1960’s. These post-Depression era instruments were mostly small console and spinet pianos, as well as small apartment size baby grands.
