Alan D. English of the DuPont Corporation was an American physicist.
He was awarded the status of Fellow[1] in the American Physical Society,[2] after being nominated by their Division of Polymer Physics in 1989,[3] for contributions to the development of a description of polymer segmental dynamics from solid-state NMR data, which incorporates the variability of both spatial and temporal coordinates with temperature and is applicable to both semicrystalline and amorphous polymers.
