The Brentwood Summer Institute on Nuclear and Particle Physics at Intermediate Energies was the second of its kind organised by the TRIUMF group of Universities, the first taking place at Banff in 1970. With the advent of initial beams at the new meson facilities at LAMPF, SIN, NEVIS, CERN S.C. and TRIUMF it was an eminently suitable time for an in-depth study of some of the science which will be possible when these accelerators achieve their design intensities in proton and meson beams. The organizing committee, comprising: Univ. of Alberta G.A. Beer Univ. of Victoria J.M. Cameron J.M. McMillan U.B.C. D.F. Measday U.B.C. R.M. Pearce Univ. of Victoria J.E.D. Pearson U.B.C. J.B. Warren U.B.C. wishes to acknowledge the financial support provided by the North Atlantic Treaty Organisation, the National Research Council of Canada, and Atomic Energy of Canada Ltd., without which the Institute could not have been held. Also we wish to acknowledge the helpful advice of the Scientific Committee of NATO and of Dr. T. Kester, Secretary of this Committee. Many persons from the University of Victoria and the University of British Columbia helped with the local arrangements and we are grateful to them and particularly to the staff of Brentwood College who made the stay of the participants such a pleasant one.
