This is a nice book to have around; it reflects careful scholarship and is filled with interesting material. ... there is much to like about this book. It is quite detailed, contains a lot of information, is meticulously researched, and has an extensive bibliography. Anyone interested in the history of mathematics, or abstract algebra, will want to make the acquaintance of this book. (Mark Hunacek, MAA Reviews, June 24, 2019)
