About Hans Jenny

Hans Jenny, a world authority on soils and their formation, died in 1992 at the age of 92. He was an emeritus professor of soil science in CNR and his contributions to the study of soils had a major impact on many scientific fields ranging from agriculture, soil conservation and ecology to geography and geology.

Jenny’s seminal book, Factors of Soil Formation, written in 1941, made him one of the most outstanding philosophers and thinkers in soil science. Jenny and his wife, Jean, actively worked to preserve numerous wildlands in California and the West so that future generations could benefit. A native of Switzerland, Jenny came to the US in 1926, and joined the Berkeley faculty in 1936. He retired in 1967, but continued to work and conduct research until his death in 1992.

Hans and Jean were instrumental in preserving the famous pygmy forest of Mendocino County as part of the Jug Handle State Reserve. The Pygmy Forest was later named the Hans Jenny Pygmy Forest Reserve.

The memorial fund was set up to support of graduate students in Soil Sciences as well as to support an annual public lecture.
