The steam whistle used on steam locomotives was developed by Robert Stephenson in the early 19th century. Although the concept of using steam to produce sound existed before, Stephenson's design, introduced around 1820, effectively utilized the steam whistle as a signaling device for trains. His innovation significantly improved communication and safety on railroads.
