  The alternative pilot-wave theory of quantum phenomena -- associated
especially with Louis de Broglie, David Bohm, and John Bell -- reproduces the
statistical predictions of ordinary quantum mechanics, but without recourse to
special \emph{ad hoc} axioms pertaining to measurement. That (and how) it does
so is relatively straightforward to understand in the case of position
measurements and, more generally, measurements whose outcome is ultimately
registered by the position of a pointer. Despite a widespread belief to the
contrary among physicists, the theory can also account successfully for
phenomena involving spin. The main goal of the paper is to explain how the
pilot-wave theory's account of spin works. Along the way, we provide
illuminating comparisons between the orthodox and pilot-wave accounts of spin
and address some puzzles about how the pilot-wave theory relates to the
important theorems of Kochen and Specker and Bell.
