The Adler Organ Company was established by Cyrus L. Adler in the late 19th Century in Louisville, KY.  The firm originally built “Adler” and “Loreto” organs and also built Beckwith organs for Sears, Roebuck & Co. and Crown organs for George P. Bent under secret contract.  In 1903 the firm was reorganzed as “The Adler Manufacturing Company” at which time the firm began manufacturing pianos in addition to organs.  In addition to selling pianos under the “Adler” brand name, the firm also built a successful line of pianos under the “Southern Grand” brand name.

Instruments built by Adler were known to be of very good quality, and they were made affordable by aggressive financing and payment installment options.  Adler pianos & organs were sold primarily through mail order and larger retail music stores throughout the United States.  Adler went out of business in 1928.
