Description
Traditionally, only musicians could reliably produce tones of a specific frequency. With a siren, even scientists could produce specific tones. Charles Cagniard de la Tour (1777-1859), a French engineer, described the first successful siren in 1819. This example is of that sort. It came from the Department of Physics at Indiana University. The inscription reads “Jas. W. Queen & Co. / Philadelphia.”
