This chapter aims to liberate the ether from its historiographical assignment to classical physics, instead considering its role in debates surrounding the future of the discipline. Focusing on the British case, it explores the discussions underway in professional spaces between 1909 and 1914, suggesting that a physicist’s commitment to the ether does not classify them as a ‘classicist’ but rather as an advocate of continuity in the discipline. It then examines the ether’s ‘popular’ life following the well-publicised 1919 eclipse expedition, and the subsequent expository efforts by the ‘classical’ Oliver Lodge and ‘modern’ Arthur Stanley Eddington. By moving beyond a traditional approach that divides physics and physicists into classical and modern, this chapter suggests a more substantial role for the ether in professional and popular early twentieth-century British physics.
