Emanuel Epstein

Emanuel Epstein (November 5, 1916 – December 4, 2022) was a German-born American plant physiologist and biochemist who spent most of his academic career at the University of California, Davis. He was a leading figure in the study of plant mineral nutrition and root physiology, and is widely regarded as a major contributor to the modern understanding of ion transport in plant cells. Epstein was elected to the National Academy of Sciences and remained scientifically active well into his later years, living to the age of 106. As a Jewish child growing up in Europe during the interwar period, he experienced the rising restrictions and persecution of the 1930s, prompting his family to leave Germany while he was still young. He helped establish silicon as a beneficial element for many plant species, showing that it can enhance growth, stress tolerance, and disease resistance, particularly in grasses and crop plants. His research played a key role in integrating silicon into broader frameworks of plant nutrition and agricultural management.
