The Aeolian Company was founded by New York City piano maker William B. Tremaine as the Æolian Organ & Music Co. (1887) to make automatic organs and, after 1895, as the Æolian Co. automatic pianos as well. He had previously founded the Mechanical Orguinette Co. in 1878 to manufacture automated reed organs. The manufacture of residence or "chamber" organs to provide entertainment in the mansions of millionaires was an extremely profitable undertaking, and Aeolian virtually cornered the market in this trade, freeing them from the tight competition of church-organ building with its narrow profit margins. Elaborate cases and consoles were often featured in residence organs. In other installations, the pipes were hidden behind tapestries, under or above staircases, or spoke from the basement through grilles or tone chutes. They also made Organettes and Player Pump Organs for the "Working Man" to buy.
The pianola, a pneumatic player piano, soon after became extremely popular. It had been invented in 1895 by Edwin S. Votey, president of the Farrand & Votey Organ Co., Detroit. In 1897, Votey joined Aeolian  and in 1900 the firm obtained the patent for such instruments.
In 1903, Tremaine absorbed a number of companies making self-playing instruments, including the [Albert] Weber Co., a New York piano maker since 1852, into the Aeolian, Weber Piano & Pianola Co.
In 1904 Aeolian sued the Los Angeles Art Organ Company for patent infringement of its player mechanism, leading to court victories that effectively shut down a competitor. Other patent lawsuits were not always successful.
As the pianola, in its turn, was supplanted by the newer Æolian’s “Duo Art” reproducing piano (1913), which could reproduce the sound of a famous artist playing without manual intervention, the Æolian, Weber Piano & Pianola Co. became the world’s leading manufacturer of such roll-operated instruments.
In 1916 the Æolian Co. started making Vocalion phonographs and in 1917/8 started Vocalion Records, a maker of high-quality discs which in December 1924 was sold to Brunswick Records. The phonograph was one of the main factors in the demise of the player piano, although Starr made players and records as well as pianos. An attempt of the company to engage in the production of church and concert organs resulted in important installations at Duke University Chapel and Longwood Gardens. It was undermined by the Great Depression, during which the organ division was merged with the E.M. Skinner Organ Co. to become the Aeolian-Skinner Organ Co., a leading builder until the 1970s. As the popularity of the player piano faded with the rise of the gramophone and radio, the company merged in 1932 with the American Piano Corp. (itself a 1930 consolidation of Chickering & Sons, Knabe & Co., and other manufacturers). The combined company was the Aeolian Corp. in 1959; it declared bankruptcy in 1985.
Interesting enough, it is the Organettes and the Player Pump Organs that have survived today and still are collected and enjoyed by their collectors. So loved are these smaller machines, they have been restored and in fact there are places to buy recuts of the original music. An example of a surviving, working piano can be seen and heard at Peary's Eagle Island State Historical Site, Harpswell, Maine.
An example of a surviving, working organ can be seen and heard at Reynolda House Museum of American Art in Winston-Salem, NC. On January 27, 1917, R. J. Reynolds contracted the Aeolian Company of New York for a pipe organ with four keyboards and a pedal footboard. Today, the organ has approximately 250 organ rolls and is played in the afternoon for visitors.
Æolian was first located at 841 Broadway, in the heart (and soul) of the piano district; the company later moved to 23rd Street, and then to 360 Fifth Avenue. Aeolian Hall (1912–13), 33 West 42nd Street, housed the firm’s general offices and demonstration rooms as a recital hall on the 43rd Street side, where many noted musicians performed, and was where the first Vocalions were made. The building was sold by Aeolian in 1924. The firm's pipe-organ factory was in Garwood, N.J., until the merger with the E.M. Skinner Co.
The firm returned to Fifth Avenue in 1925. The firm’s facilities in the new Aeolian Building included a 150-seat recital hall, recording studios for Duo Art piano rolls, offices, design studios, drafting rooms, and a director’s room in the upper stories. The Aeolian Company (as Aeolian American Corp.) remained in the Aeolian Building until 1938, after which it leased half of Chickering Hall on West 57th St.
It was Congressional suspicion of the market power of the Aeolian company during the early 20th century that prompted adoption of the first compulsory license system in U.S. copyright law, for the mechanical reproduction of musical compositions, a category that included piano rolls.
The player piano deeply troubled popular music composers such as John Philip Sousa. Sousa worried that the pianos would kill the public’s demand for sheet music, and sheet music was the source of composers’ copyright royalties. To make matters worse, the player piano companies refused to pay royalties to composers for the songs they put on player piano rolls. These rolls were scrolls of paper with holes punched out in patterns that instructed the piano how to play a particular song. The rolls, argued the player piano companies, did not “copy” the composers’ musical compositions. As a result, they were perfectly legal.
The Supreme Court, in its 1908 opinion in White-Smith Music Publishing Company v. Apollo Company, sided with the player piano companies. The Court held that because humans could not read player piano rolls, they were not in fact copies of the musical compositions they encoded.
The result in White-Smith lasted but a year before Congressional action. The Copyright Act of 1909 mandated that all musical compositions would be subject to a compulsory license. In short, since 1909 the copyright law has allowed musicians to copy others’ songs by mechanical means (e.g, via piano roll or phonorecord/sound recording) without asking permission, so long as they paid a specified fee to the original songwriter.
Anticipating that Congress was about to overturn White-Smith, Aeolian Company moved swiftly to buy up song rights from musicians and publishing companies so it could copy them onto player piano rolls. Aeolian’s competitors quickly complained to Congress about Aeolian’s attempt to corner the music market. Congress responded with the invention of the cover song rule.
