David William Dye FRS (30 December 1887 – 18 February 1932) was an English physicist.
After attending the local Technical College in Portsmouth he studied for a B.Sc at London University.
He then served an apprenticeship at the British Thomson-Houston Company at Rugby before joining the National Physical Laboratory in 1910, where he was appointed Head of the Electrical Standards and Measurements Section in 1919.
He eventually turned to the piezo-electrical crystal to develop the first quartz clock.
His application citation stated that he has established accurate and permanent standards of capacity and inductance suitable for radio frequencies, and has developed a self-contained standard of radio frequencies of high accuracy embodying a tuning fork control.
