His reputation rapidly
grew and he worked on projects for
the Seagram and Shell buildings
with Rothko, Dali and Pollock. Between
1954 and 1968 he showed at least
once a year, with nineteen one man
shows in galleries and five in International
museums in places as diverse as
Peru, Amsterdam, Detroit and Linz..
He travelled frequently to America
and Europe and in 1970 he was awarded
a Churchill Fellowship to make further
studies into the origin, development
and practice of murals and enamels
travelling to Mexico, Guatemala,
Japan, India and Iran.
Above all it was very important
to him to be taken seriously as
a fine art painter and especially
in the very medium he invented.
Nobody before had ever produced
such large murals that could last
for thousands of years. His international
status, free spirit, prolific output,
the sheer scale and diversity of
his work made him one of the unique
entities of the post war art world.
In enamel Knapp realised the dream
of the ancient Greeks who searched
for a suitable medium in which to
preserve polychrome colour for perpetuity.
In the last 70’s Knapp finally
settled in the countryside with
his wife Cathy, where he had already
constructed a large furnace for
firing and continued to paint and
experiment with enamels and sculpture.
He also spent several months of
the year in France drawing and working
in acrylic on canvas. It was here
he produced some of his most peaceful
and reflective work.
