Frederick Campion "Camp" Steward FRS[1] (16 June 1904 – 13 September 1993) was a British botanist and plant physiologist.
He was educated at Heckmondwike Grammar School and then attended the University of Leeds, where he gained a BSc in biology in 1924 and then undertook research in the botany department.
After the war he returned to the USA, holding appointments at the Universities of Chicago and Rochester before finally moving to Cornell in 1950.
Ever fascinated by the unfolding processes of growth and development, Steward set out to study the behaviour of mature cells, isolated from carrot roots, when cultured in sterile nutrient culture media (liquid endosperm, or coconut water), using specially designed flasks and the rotating 'Steward' wheel.
[1] His candidature citation read: 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".
