Critic, arbiter of taste, renowned authority on Renaissance painting, and oracle to millionaire art collectors, Bernard Berenson was the most formidable presence in the Anglo-American art world for more than thirty years. His Villa I Tatti near Florence was a magnet for European and American intellectuals; he was able to say, late in life, that most of the Italian paintings that had come to the United States had “my visa on their passport.” Twenty years after his death he remains a paradoxical figure—fit challenge for a Pulitzer Prize–winning biographer.

The story of the making of the connoisseur spans four decades, from Berenson’s childhood in Lithuania and in an immigrant enclave in Boston to the triumphant tour of the United States that confirmed his international reputation. Ernest Samuels interweaves with great skill the many threads of the narrative. No less fascinating than Berenson’s own development, and the accidents that shaped his career, are his relations with an extraordinary cast of characters whose lives impinged on his—among them George Santayana, William James, Bertrand Russell, Logan Pearsall Smith, Norman and Hutchins Hapgood, Oscar Wilde, Vernon Lee, the Michael Fields, Gertrude Stein, Edith Wharton, Roger Fry, and, most notably, the fabled Mrs. Jack Gardner. His relationship with Mary Smith Costelloe, who left her husband and children for him and eventually became his wife, was so close that the book is almost as much her story as his.

Drawing on the thousands of letters B.B. and Mary wrote and the diaries she kept, Samuels is able to convey Berenson’s thoughts and impressions as well as the outward events of these crucial years of his life. He blends sympathy and irony in his many-faceted portrayal of a complex man and a remarkable career. It is a compelling book.

Controversy swirls around Bernard Berenson today as it did in his middle years, before and between two world wars. Who was this man, this supreme connoisseur of Italian Renaissance painting? How did he support his elegant estate near Florence, his Villa I Tatti? What exactly were his relations with the art dealer Joseph Duveen? What part did his wife, Mary, play in his scholarly work and professional career? The answers are to be found in the day-to-day record of his life as he lived it—as reported at first hand in his and Mary’s letters and diaries and reflected in the countless personal and business letters they received. His is one of the most fully documented lives of this century. Ernest Samuels, having spent twenty years studying the thousands of letters and other manuscripts, presents his story in absorbing detail.

Berenson helped Isabella Stewart Gardner build her great collection and performed similar though lesser services for other wealthy Americans. It was merely an avocation and a useful source of income; his vocation was scholarship. But after 1904, when the book opens, his expertise was in ever-greater demand: a purchaser’s only assurance of the authorship of an Italian painting was the opinion of an expert, and in this field Berenson was preeminent. Increasingly he was drawn into the lucrative world of the art dealers; inevitably Joseph Duveen found it essential to enlist his services, at first ad hoc, then by contractual agreement. Samuels charts the course of Berenson’s long association with Duveen Brothers, detailing the financial arrangements, the humdrum chores and major contested attributions, the periodic clashes between the stubborn scholar and the arrogant entrepreneur.

The portrayal of Berenson’s relationship with Mary is especially intriguing: a union of opposites in all but brains and wit, bonded—despite love affairs, jealousies, recriminations—no longer by passion but by shared concerns. Impinging on their lives are those of a huge circle of friends and acquaintances in America and the beau monde of Europe. Both as biography and as a chapter of social and cultural history, it is a compelling book.
