... a fascinating biography ... Subramanian...recounts Haldane’s communist adventures with brio ... A Dominant Character is the best Haldane biography yet. With science so politicized in this country and abroad, the book could be an allegory for every scientist who wants to take a stand.
... an exquisite literary expedition into J.B.S.’ boyhood, his family history, his schooling ... Haldane’s personality, his accomplishment, calibre and the time that he inhabited makes him a naturally compelling subject and much of the facts of his life are well documented, Subramanian gives compelling context ... From the history of the development of biology to the Spanish Civil War, Subramanian skillfully mixes archival research and deep scrutiny of J.B.S.’ work to portray — what can be safely assumed — a breed of scientist almost impossible to imagine today.
