Walter Frederick Sutherst, agricultural chemist, was the co-author of Friedrich Kehrmann for a paper, "Ueber Naphtinduline und Naphtazonium-Verbindungen", in the Berichte der Deutschen Chemischen Gesellschaft in 1899. The next year he submitted his doctoral thesis titled Recherches sur les derives de naphtazonium (40 pp) at Geneva, Switzerland. During the next decade he published several articles on topics in agricultural chemistry. Three of his articles were published in South Africa, namely "Manganese compounds as fertilisers for maize" (Transvaal Agricultural Journal, 1907/8 Vol. 6, p. 437), "The conservation of soil moisture" (Agricultural Journal of the Cape of Good Hope, 1908, Vol. 33(4), pp 511-513) and "A plea for sunflower cultivation" (Ibid, 1909, Vol. 34(1), pp 61-62). By 1908 Sutherst resided in the Eastern Cape and was affiliated with Marist Brothers College in Uitenhage. [Marist Brothers, a Roman Catholic Order, opened this school in 1884]. In 1905 he became an associate of the Institute of Chemistry of Great Britain and Ireland.
Walter Frederick Sutherst, presumably the same person, went to the United States in 1909 and resided in Berkeley, California, by 1918. In 1924 he was granted patents relating to the manufacture of sulpher and other chemical substances.
