The Ahlstrom Piano Company was established by C. A. Ahlstrom in 1875.  The factory was located at 112-114 East Second Street, Jamestown, New York. Ahlstrom originally built a full line of square grand and upright pianos, but discontinued square pianos before 1895. After the turn-of-the-century, the firm added grand pianos and player pianos to their product line.

The Ahlstrom Piano Company was known for building very good quality, durable pianos and player pianos. In addition to their Ahlstrom brand, they built and sold pianos under the brand names of Artone, Artonola, and Arto-Grand. The Ahlstrom Piano Company went out of business in about 1926.
