Smell-O-Vision was a system that released odor during the projection of a film so that the viewer could "smell" what was happening in the movie. The technique was created by Hans Laube and made its only appearance in the 1960 film Scent of Mystery, produced by Mike Todd Jr., son of film producer Mike Todd. The process injected 30 odors into a movie theater's seats when triggered by the film's soundtrack. Roughly similar concepts of integrating odor experiences into entertainment performances have dated back to at least 1868 for live theatre, with the first usage for film being in 1906, and other similar approaches were used in the same era, such as General Electric's "Smell-O-Rama" of 1953 and the competitive system called "AromaRama" in 1959. Various similar concepts have also been used since then, such as John Waters's "Odorama" enhanced version of his film Polyester in 1982. History In 1868, a novel effect was used at the Alhambra Theatre of Variety in London when Rimmel scent was sprayed into the theatre during the Magic Dance of The Fairy Acorn Tree. The use of scents in conjunction with film dates back to 1906, before the introduction of sound. In this first instance, a 1958 issue of Film Daily claims that Samuel Roxy Rothafel of the Family Theatre in Forest City, Pennsylvania, placed a wad of cotton wool that had been soaked in rose oil in front of an electric fan during a newsreel about the Rose Bowl Game. However, between 1903 and 1915, there were no games held, so it is unknown what the newsreel was about, although the Rose Parade (which has been held annually since 1890) seems likely. In 1916, the Rivoli Theatre in New York was equipped with the ability to pump scents into the theatre for the short film Story of the Flowers. During the screening of the film Lilac Time in 1929 at the Fenway Theatre in Boston, Massachusetts, the manager poured a pint of lilac perfume into the plenum chamber of the theatre's ventilation system so that the audience would smell lilac when the film's title appeared. The same year, during the showing of The Broadway Melody, a New York City theater sprayed perfume from the ceiling. Arthur Mayer installed an in-theater smell system in Paramount's Rialto Theater on Broadway in 1933, which he used to deliver odors during a film. However, it would take
