The Advances in Cancer Research series provides invaluable information on the exciting and fast-moving field of cancer research. A very special event the Nobel Minisymposium, Molecular Oncology From Bench to Bedside, held at the Karolinska Instituet, in Stockholm, Sweden, was marked the celebration of George and Eva Klein s combined 160th birthday. To honor this occasion, this 2nd of two volumes brings together contributions by their former students, colleagues and collaborators of the past fifty years into a volume of Advances in Cancer Research dedicated to George and Eva. Over a decade ago, a subdivision of ACR called Foundations in Cancer Research was initiated and the tributes honoring the Kleins bodies of work presented at the minisymposium are especially appropriate for the series.
