The award was made for the poster describing the work of Dr. Hans
Stauss in the laboratory of Professor Hans Schreiber in Chicago
on the grounds that it solves, or at least goes a long way towards
solving, a longstanding enigma in tumour immunology, namely, the
nature of the tumour-specific transplantation antigens on ultraviolet-induced
This is a problem of great general interest because of the unusually
strong potency of these antigens and also be Department of Biology,

WC1 E 6BT cause of their analogy with the antigens of human skin
cancer. In this connection, it should be remembered that skin cancer
is one of the few forms of human neoplasm that is under strong immune
surveillance, as judged from the elevated incidence of these cancers
in immunosuppressed individuals.
Indeed, Harald Zur Hausen at this meeting discussed these cancers
and their antigens in the context of papilloma virus infection.
The judges liked Dr. Stauss' work for its use of a judicious combination
of classical transplantation techniques and modern molecular biology.
In addition, the poster itself was masterly.
