Theodor Schwenk (1910–1986) was a pioneer in water and flow research. He founded the Institute for Flow Sciences for the scientific study of water's movement and life-giving forces. A well-known author and lecturer, he contributed original insights and methods to the production of homeopathic, anthroposophic medicines. He developed "drop-pictures" for analyzing water quality and methods for healing polluted, "dead" water. Schwenk gained public recognition with the publication of Sensitive Chaos: The Creation of Flowing Forms in Water and Air.
