  Wolfgang Kummer was well known for his passion for axial gauges and for the
formulation of gravity in terms of Cartan variables. The combination of the two
applied to two dimensional dilaton gravity is the basis of the "Vienna School",
which provided numerous significant results over the last seventeen years. In
this review we trace the history of this success with particular emphasis on
dilaton supergravity. We also present some previously unpublished results on
the structure of non-local vertices in quantum dilaton supergravity with
non-minimally coupled matter.
