Query: On Higher Spin Theory: Strings, BRST, Dimensional Reductions   We briefly review some modern developments in higher spin field theory and
their links with superstring theory. The analysis is based on various BRST
constructions allowing to derive the Lagrangians for massive and massless
higher spin fields on flat or constant curvature backgrounds of arbitrary
dimensions.
