  After a brief history of heavy quarks, I will discuss charm, bottom, and top
quarks in turn. For each one, I discuss its first observation, and then what we
have learned about production, hadronization, and decays - and what these have
taught us about the underlying physics. I will also point out remaining open
issues. For this series of lectures, the charm quark will be emphasized. It is
the first of the heavy quarks, and its study is where many of the techniques
and issues first appeared. Only very brief mention is made of CP violation in
the bottom-quark system since that topic is the subject of a separate series of
lectures by Gabriel Lopez. As the three quarks are reviewed, a pattern of
techniques and lessons emerges. These are identified, and then briefly
considered in the context of anticipated physics signals of the future; e.g.,
for Higgs and SUSY particles.
