Clark (1810-1841) was regarded as quite a poetical celebrity in his day. He was twin brother of Lewis Gaylord Clark, editor for nearly thirty years of the Knickerbocker Magazine, and who died in 1873 — a delightful companion and amiable man, whose specialty was a quick, discriminating humor, rising often into wit. They were born at Otisco, N. Y. Willis settled in Philadelphia, where he edited the Gazette, and wrote poems, a complete edition of which was published in New York in 1847. He also contributed a series of literary miscellanies, under the title of Ollapodiana, to his brother's magazine. These were collected into a volume, and published in 1844.
