\section*{Foreword}
\addcontentsline{toc}{section}{Foreword}

The international workshop entitled {\it The Higgs Puzzle---What Can we Learn
from LEP2, LHC, NLC, and FMC?\/} took place on 8--12 December 1996 at Ringberg
Castle, which overlooks Lake Tegernsee in the foothills of the Bavarian Alps,
one of the most picturesque locations to be found in the whole of Germany.
The castle was built during the first half of this century by Duke Luitpold
in Bavaria (Herzog Luitpold in Bayern), a member of the Wittelsbach family,
who ruled Bavaria over 800 years, and his friend Friedrich Attenhuber, an
all-round artist, architect, and interior decorator.
The castle is entirely their creation, from the massive Renaissance-inspired
exterior right down to the fittings and furniture, which, in every detail,
were designed by Attenhuber himself and executed by native craftsmen.
Attenhuber also painted every single picture hanging in the castle.
He found his models in the farmhouses around Lake Tegernsee.
The castle embodies all trends of art and styles which dominated the first
half of this century, combined with local Alpine originality and the
individual creative power of its constructors. 
According the the Duke's last will, the castle passed into the hands of the
Max Planck Society after his death, in 1973.
The castle was then transformed into a conference venue where scientists can
exchange their latest ideas and discuss problems with their colleagues from
all over the world in beautiful surroundings and in a relaxed mountain
atmosphere, high above the daily business activities.

This event has continued a series of Ringberg workshops on electroweak physics
in high-energy reactions, which include:
{\it Hadronic Matrix Elements and Weak Decays}
on 17--22 April 1988;
{\it Radiative Corrections for $e^+e^-$ Collisions}
on 3--7 April 1989;
{\it High Precision versus High Energies in $e^+e^-$ Collisions}
on 15--19 April 1991;
{\it Perspectives of the Electroweak Interactions in $e^+e^-$ Collisions}
on 4--8 April 1993;
{\it Advances in Non-Perturbative and Perturbative Techniques}
on 13--19 November 1994;
{\it Perspectives for Electroweak Interactions in $e^+e^-$ Collisions}
on 5--8 February 1995.
On the occasion of the 1996 Ringberg workshop, forty-two experts of
elementary-particle physics, both theoreticians and experimentalists, from
twenty-seven universities and research institutions in ten countries
congregated to present their latest results on the various aspects of Higgs
phenomenology.

The motivation for this workshop may be summarized as follows.
Despite the great success of the standard model of electroweak and strong
interactions to describe the phenomena observed in high-energy-physics
experiments, the mechanism by which the elementary particles are endowed with
their masses is yet to be unraveled. Does nature choose the Higgs mechanism
of spontaneous symmetry breaking as predicted by the standard model, or do we
need some alternative explanation? The purpose of the workshop was to capture
new trends and ideas in this exciting area of fundamental physics, and to
explore the potential of recent (CERN LEP1), present (CERN LEP2, DESY HERA,
Fermilab Tevatron, SLAC SLC), and future (CERN LHC, Next Linear Collider,
First Muon Collider) colliding-beam experiments to shed light on the Higgs
puzzle.

There was a total of 35 presentations of 45 minutes each.
This proceedings volume is to give a comprehensive account of the novel ideas
and results discussed by the speakers.
The topics include:
experimental and theoretical status reports from LEP1, LEP2, LHC, NLC, and
FMC;
electroweak precision tests;
multi-loop calculus;
Callan-Symanzik and renormalization-group equations;
lattice field theory;
gauge independence and invariance;
resonant CP violation;
strongly interacting Higgs sector;
effective Lagrangians;
supersymmetry;
extended technicolor;
dynamical symmetry breaking;
compositeness;
grand unification;
electroweak phase transition;
baryogenesis; and
noncommutative geometry.
We also hope that the high-energy-physics community at large will find this
document useful in their ongoing efforts of solving the Higgs puzzle.

At this point, I should like to thank my friends and colleagues who have
contributed their shares to these proceedings.
I am indebted to the workshop secretary, Mrs.\ Renate Saffert, for her
assistance before, during, and after the workshop.
Last but not least, I am grateful to Wolfgang Hollik and Stefan Pokorski for
contributions from their EU budgets towards the cost of catering and lodging,
and to the Werner Heisenberg Institute for their generous financial support.

Finally, I wish to express my serious concern against the plan of the Max 
Planck Society to eliminate 61 positions in the Werner Heisenberg Institute,
Germany's second largest high-energy-physics laboratory after DESY, during the
next few years.
I hope that the responsible persons will reconsider this detrimental measure 
against the heritage of Max Planck and Werner Heisenberg, and the progress in
elementary particle physics, the most fundamental area of research there is in
natural sciences.
