Ehrenfried Pfeiffer (1899-1961) was born in Munich. He visited the USA several times in the 1930s, was awarded a doctorate for his groundbreaking Sensitive Crystallisation theory as a blood test for detecting cancer, and emigrated there in 1940. He pioneered biodynamic agriculture in the USA and helped found the Biodynamic Farming & Gardening Association. He died in Spring Valley, New York.
