I were privileged to witness and perform the nice development of information on chemical carcinogenesis and mutagenesis because 1939 whilst I entered graduate tuition in biochemistry on the college of Wisconsin­ Madison. I instantly began to paintings with the carcinogenic aminoazo dyes un­ der the path of Professor CARL BAUMANN. In 1942 I joined a fellow graduate scholar, ELIZABE1H CAVERT, in marriage and we quickly started out a joyous half­ nership in learn on chemical carcinogenesis on the McArdle Laboratory for melanoma study within the college of Wisconsin scientific institution in Madison. This collaboration lasted forty five years. i'm very thankful that this quantity is dedi­ cated to the reminiscence of Elizabeth. the $64000 and sundry themes which are reviewed the following attest to the ongoing progress of the fields of chemical vehicle­ cinogenesis and mutagenesis, together with their fresh and fruitful union with viral oncology. i think very confident concerning the program of data in those fields to the eventual answer of various difficulties, together with the detection and estimation of the hazards to people of environmental chemical cancer causing agents and re­ lated factors.
