A theoretical <physicist> who identified <electron-phonon interaction> as a promising basis for understanding <superconductivity>. In 1950, his independent theoretical proposal and the experimental <superconducting isotope effect> directed attention to lattice vibrations as part of the mechanism. This helped explain why understanding electron motion alone was insufficient: the response of the surrounding crystal also affects electronic behavior.<Electron-Phonon Interactions and Superconductivity by John Bardeen>[Section 1, introduction: 1950 isotope-effect discovery and Fröhlich's independent proposal]{ref}
