The unofficial biographer of the Pfaff’s crowd, William Winter was born in coastal Massachusetts, and his mother died when he was young. Winter attended school in Boston; he also went to Harvard Law School but decided not to practice ("William Winter, 19). By 1854 he had already published a collection of verse and worked as a reviewer for the Boston Transcript; he befriended Pfaffian Thomas Bailey Aldrich after reviewing a volume of his poetry. He relocated to New York in 1856 "because he believed [the city] offered the best field for writers" (Levin 153).
