Lawrence Einhorn wanted to practice general medicine alongside the father he revered. Life interfered with that dream, but along the way, he discovered the cure for testicular cancer. In 1974, patients facing a disease with a then five-percent cure rate followed the lead of an ambitious but humble young scientist who had unwittingly concocted a miracle mix of chemotherapy. Dr. Einhorn, a Conquer Cancer board member and generous donor, speaks with friend and colleague Patrick Loehrer about his “walk on the moon” that outsmarted what was once the deadliest form of male cancer.
