This is an edited 'autobiography' completed by Anderson in his eighties and aimed at his growing grandchildren. Edited by his daughter-in-law it is then best read as a memoir rather than an historical primary source. That aside it is a captivating read, illustrating a time, particularly pre-war (World War II) when physics was a small-scale and equipment was 'hand-built'. It does present an interesting perspective on the discovery by Anderson and his co-worker Seth Neddermeyer of both the positron and the muon. Anderson was a pioneer in cloud chamber analysis of cosmic rays and was awarded (a half-share) in the 1936 Nobel Prize in physics, becoming the youngest ever winner of that prize. His interesting relationship with Robert Millikan, the doyen of early American experimental physics is glimpsed tantalisingly, without revealing any of what would have been a fascinating generational exchange between two creative and persistent experimentalists. The autobiography is sadly light on his non-scientific life; his marriage, "the most important event in my life", rates barely a page in total. An introductory read, it is sadly the only biographical book on carl Anderson written to date.
