This interesting book tells the fascinating story of the evolution of mathematics at the University of California, Berkeley, from 1868 till 2006. The author describes the history of the foundation, development and transformation of the department of mathematics. The major theme is to show how a department in a state university that was, in its early history, devoted to teaching, developed into the major research centre that is among a small group of the very best departments in the USA. The most important mathematicians and their scientific works and activities are carefully presented. The author also includes some interesting and helpful discussions of mathematics instruction in California before the founding of the University of California (chapter 1), as well as discussions on the role of the Mathematical Sciences Research Institute (chapter 19) in the development of mathematical research in the USA. The author shows the development of the mathematics department within the history of the university, the social, political and financial history of the state of California, as well as the history of American mathematics and the American Mathematical Society. The excellent photos, index and bibliography are included at the end of book. The book can be recommended to anybody who is interested in the development of mathematical societies and teaching and research in the 19th and 20th centuries in the USA.
