He was scientifically prolific, with over 195 publications listed in PubMed at this writing, and several more still in press. His scientific contributions will live on and will be the basis for further advances for years to come. Below I highlight his contributions to our understanding of four cancers: the desmoplastic small round cell tumor, neuroblastoma, prostate cancer, and breast cancer. The perspective here is my own as a friend and scientific colleague, and I apologize in advance for aspects of his work and people in his career that I have failed to include.
