was concurrent development of similar instruments. Jacob Alexandre and his son Édouard introduced the orgue mélodium in 1844. Hector Berlioz included it in his Grand traité d'instrumentation et d'orchestration modernes, published in Paris by Schoenberger, [1843?] or [1844?], in an « Instruments nouveaux » section on pp. 290-92, and in the 1856 reprint, found on pp. 472-77 in Peter Bloom's critical edition published by Bärenreiter, Vol.24, in Kassel and New York, 2003. Berlioz also wrote about it in several subsequent journals (Bloom, p. 472, nn. 1 & 2). He used it in 1 work: L'enfance du Christ, Part 1, scene vi, where it is off stage. When he conducted it in Weimar on 21 February 1855, it was played by Franz Liszt (Bloom, p. 474, n. 3).A mechanic who had worked in the factory of Alexandre in Paris emigrated to the United States and conceived the idea of a suction bellows, instead of the ordinary bellows that forced the air outward through the reeds. Beginning in 1885, the firm of Mason & Hamlin, of Boston made their instruments with the suction bellows, and this method of construction soon superseded all others in America. The term melodeon was applied to concert saloons in the Victorian American West because of the use of the reed instrument. The word became a common designation of that type of resort that offered entertainment to men. Harmoniums reached the height of their popularity in the West in the late 19th and early 20th centuries. They were especially popular in small churches and chapels where a pipe organ would be too large or expensive; in the funeral-in-absentia scene from Mark Twain's The Adventures of Tom Sawyer, the protagonist narrates that the church procured a "melodeum" (a conflation, likely intended by Twain for satirical effect, of the names "melodeon" and "harmonium") for the occasion. Harmoniums generally weigh less than similar sized pianos and are not easily damaged in transport, thus they were also popular throughout the colonies of the European powers in this period not only because it was easier to ship the instrument out to where it was needed, but it was also easier to transport overland in areas where good-quality roads and railways may have been non-existent. An added attraction of the harmonium in tropical regions was that the instrument held its tune regardless of heat and humidity, unlike the piano. This "export" market was sufficiently
