Obituary of John W. Francis, M.D., LL.D. (1861). Tuckerman, "as America's most knowledgeable and dedicated Italophile, missed few opportunities to argue the case for Italian freedom, even though he expressed doubt ... whether Italians were ready to govern themselves. He read and spoke Italian [and] made extended visits to
Italy in 1833-34 and 1837-38...." Tuckerman was a close friend of
Herman Melville's and was prominent in the literary life of New York City after 1845. Tuckerman wrote a book review for the
North American Review that indirectly led to the United States offering
Giuseppe Garibaldi a position as major general in the Union army during the
Civil War. The review included a glowing tribute to Garibaldi. When it reached Garibaldi in Italy, he asked his friend Augusto Vecchi to write a letter of thanks on his behalf. Vecchi did so and also enclosed his own letter suggesting that the United States invite Garibaldi to aid the Union cause. The suggestion reached President
Abraham Lincoln, the offer was made, but no agreement was reached because Garibaldi demanded the power to free the slaves, which Lincoln was not ready to do in 1861, and because, as the result of a misunderstanding, Garibaldi thought that he was being offered the supreme command of the Union army. ==Personal life==
