notes: label: Description
content: Traditionally, it was only musicians who could reliably produce tones of a specific frequency. With a siren, however, specific tones could be produced mechanically. Charles Cagniard de la Tour (1777-1859), a French engineer, described the first successful siren in 1819. This instrument is of that sort. It came from the University of Vermont. An inscription reads "E. Ducretet et Cie a Paris".

content: Eugene Adrien Ducretet (1844-1915) was a scientific instrument maker who, after an apprenticeship with Paul Gustav Froment, opened his own workshop in Paris in 1864. In the 1890s he worked in partnership with Leon Lejeune. He performed some of the first experiments with wireless telegraphy (radio) in France.
