Bells have existed since at least around 1600 BC. The understanding of the acoustics of bells dates from Jacob van Eyck in the 17th century and Canon Arthur Simpson in the 19th century.

For a detailed history and information about the acoustics of bells, see Bells and Their Music or search on Wikipedia for node and vibration.
