From heading a campus of the largest public university in the nation to participating in the birth of molecular biology, Robert L. Sinsheimer's experiences have given him a unique vantage point from which to view the paths that science and education have taken in the twentieth century. This book tells the story of his life, of his own growth, and of his leading role in both science and higher learning during the past fifty years. He has witnessed and participated in the birth of molecular biology, taught at leading universities, and headed a campus of the largest public university in the nation. While a student and then a researcher at MIT, and as a professor at Iowa State University and later at Caltech, Sinsheimer was a major participant in the 'molecular revolution' that radically transformed the science of life. He was also one of the first to foresee the potential of molecular biology and to draw attention to some of the ethical quandaries the new science would pose. In 1977 Sinsheimer became chancellor at the University of California, Santa Cruz, at a crucial time in the campus' evolution. He played a key part in revitalizing the educational experiment that has made the campus unique among the state's institutions of higher learning. Sinsheimer's life has been lived at the ever-advancing edge of knowledge. In simple, elegant language, he offers historical and philosophical insights into the world of science and the mind of a scientist. His reflections are both fascinating and valuable.
