Fellow of the Royal Society in March 1957. His candidature citation read: "[Steward] has contributed to knowledge of salt absorption, accumulation and transport since 1930. His earlier work established that ion accumulation was linked to metabolism at a time when this was doubted, and in this connection extensive studies of protein metabolism were undertaken. Steward and his colleagues Dent and Stepka made important early studies using the (then) new technique of chromatographic separation of amino acids. He has (following a distinguished war record as Director of Aircraft Equipment II) been successful in recent years in isolating from coconut milk the factors which promote or maintain plant cells in the embryonic or meristematic condition. Two have been identified definitely as diphenylures and a leuco-anthocyanin. His current studies are dealing with mode of action of these substances and with ion accumulation processes of meristem tissue". Steward delivered The Royal Society's Croonian Lecture in 1969 on "From cultured cells to whole plants: the induction and control of their growth and morphogenesis". He wrote more than 100 scientific journal articles and several books and was an editor and contributor to the 10 volumes and 15 books of "Plant Physiology: A Treatise" (Academic Press, 1959–1991). Family life He died in Tuscaloosa, Alabama. He had married Anne Temple Gordon, whom he met at Cornell. They had one son.
