The papers of John Edmund Bowen consist of two manuscript notebooks containing notes on lectures delivered by Professor Joseph John Thomson, Cavendish Professor of Physics at Cambridge, 1911-1912. Bowen's notes consist of detailed summaries of Thomson's lectures on subjects including the discharge of electricity through gases, recombination of ions, recent developments in researches on light and electricity, scattering of electromagnetic radiation and the quantum theory of light.
