Though a Bostonian by birth and upbringing, Winslow Homer lived and maintained his studio in New York City for twenty-five years, establishing himself as a leading figure in New York's art world. In 1881, determined to broaden his status as a painter, Homer journeyed to Great Britain. During his trip, major changes appeared in nearly everything he did as a painter. The changes came so rapidly during his first months abroad that there can be little doubt that the crucial turning point occurred during his first weeks in London. After his return to New York in November of 1882 and during his later years in Maine, the sequence of major oil paintings that came from his brush owed much, in the most fundamental ways, to transformations that began in London. Tatham's Winslow Homer in London: A New York Artist Abroad, 1881-1882 is the first to examine in detail this preeminent American painter's crucial weeks in London during his year and half in Great Britain.
