While not much is known about the early life of Edward Mallen, he is remembered as an artist and frequenter of Pfaff's. William Winter identifies "Edward F. Mullen" as one of the artists who frequented Pfaff’s Cave along with Launt Thompson, George Boughton, and Sol Eytinge, Jr. (Old Friends 66, 88). Walt Whitman, a close friend of his, is also quoted as saying that "Mullin" was "among the leaders" at Pfaff’s (Bohan 134; T. Donaldson 208-209).
Characterized as an "eccentric literary man not without a spice of genius," William North was born in England and eventually settled in New York City (W. Rossetti 48-49). In England he established a periodical North's Magazine, and in New York he began publishing sensational stories like "The Living Corpse" which appeared in Putnam's in 1853 and was later reprinted in the Saturday Press.
Born in County Cork and raised primarily in Limerick, Ireland, Fitz-James O'Brien moved to New York City in 1852. Descending from an Anglo-Irish landholding family, O'Brien received his inheritance (estimated at £8000) at about the age of 21. Between 1849 and 1851, it is believed that O'Brien edited a failed literary magazine called The Parlour Magazine of the Literature of All Nations and squandered his inheritance (Wolle 21). Leaving England almost penniless, O'Brien immigrated to America and made the U.S.
Charles Dawson Shanly emigrated to New York City from Ireland via Canada and was working as the Assistant Secretary of the Department of Public Works in 1857. In New York City during the late 1850s and 1860s, Shanly was productive as a journalist and editor at such publications as Vanity Fair, Mrs. Grundy, the New York Leader, the Atlantic Monthly, and the New York Saturday Press.
Remembered as "a man of brilliant talent and singular charm," Edward Wilkins' career included the roles of editorial writer, musical and dramatic critic, and playwright. He was raised in Boston where he began his journalism career.
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).
