The essays in this book, by L.M. Brown, M. Dresden, R.S. Mills, S.S. Schweber, T.Y. Cao, and D.V. Shirkov, discuss the history of renormalization theory from the late 19th century to the 1950s and the effect it has had not only on the development of field theory, but also on our ideas of what is a fundamental and what is a phenomenological theory.
