The pioneering character and continuing success of Schaal s scenic
compositions for stage sets and exhibitions is significantly due to this
field allowing him to take full advantage of his multiple talents. He
succeeds equally in the thinking and practical skills of an architect, a
painter, a sculptor, a landscape designer, an urban visionary, cineast,
and a man of literature. In works such as his installations for Berlin
Berlin (1987) or Prometheus (1998), for the Filmmuseum Berlin (2000),
and for the concentration-camp memorials Mittelbau-Dora (2006),
Bergen-Belsen (2007) or Esterwegen (2011), he always presents his own
view of the world, his own view of things."
