  In this paper we discuss some of Springer's work on unipotent elements in a
reductive groups and on representations of Weyl groups. Among the topics
considered are Springer's bijection from the unipotent variety to the nilpotent
variety, Springer's example of nonrationality of certain representations of the
Hecke algebras associated to a Weyl group and the Springer representation of
the Weyl group associated to a unipotent element.
