From the reviews: "This review is principally concerned, provides a description of Grassmann's life and an analysis of his mathematical ideas. ... In summary, I thoroughly enjoyed reading this biography, and it must surely be the seminal work on the life and times of Hermann Grassmann. ... The level of scholarship is consistently high, which is evidenced by the fact that almost ... 306 pages is devoted to references and bibliographical information. ... greatly benefited from the addition of a mathematical index." (P. N. Ruane, The Mathematical Association of America, March, 2010) "One should welcome this English translation of the German original ... . The book, intended 'to critically appreciate and explain the life and work of Hermann Gunther Grassmann (1809-1877)', does it in a clear and well documented way. ... The book is richly illustrated (47 figures) and completed with chronology of Grassmann's life and an extensive bibliography on him (16 pages)." (Roman Duda, Zentralblatt MATH, Vol. 1195, 2010)
