Particle Theory at Chicago in Late Sixties and p-Adic Strings

Abstract

As a contribution requested by the editors of a Memorial Volume for Peter G.O. Freund (1936-2018), we recall the lively particle theory group at the Enrico Fermi Institute of the University of Chicago in the late sixties, of which Peter was a memorable member. We also discuss a period some twenty years later when our and Peter's research overlapped on the topic of p-adic strings.
