N. F. Mott revived the old Philosophical Magazine and transformed it into a lively publication essentially centred on the then-new field of solid state physics, attracting writers, readers and general interest on a wide scale. After receiving a paper on point defects in crystals by Frederick Seitz that was obviously too long for the journal, Mott decided to create a new publication, Advances in Physics, for such review papers. Both publications are still active in 2017.
