Hans Jenny (16 August 1904 in Basel – 23 June 1972 in Dornach)[1] was a Swiss physician and natural scientist who coined the term "cymatics" to describe acoustic effects of sound wave phenomena.
After completing a doctorate he taught science at the Rudolph Steiner School in Zürich for four years before beginning medical practice.
[3] His work in this area included an acoustically vibrated piece of sheet metal in which small holes had been drilled in a grid.
A special edition of the Hafler Trio's work Exactly As I Say includes a DVD containing material said to be "based on and extended from techniques suggested by Prof. Hans Jenny".
Photographer Alexander Lauterwasser has also captured imagery of water surfaces set into motion by sound sources ranging from sine waves to music by Beethoven, Karlheinz Stockhausen and overtone singing.
