William Rossa Cole (November 20, 1919 – August 2, 2000) was an American editor, anthologist, columnist, author, and writer of light verse. He produced around 75 books, most of them anthologies. Cole was born William Harrison Cole on November 20, 1919, to William Harrison Cole and Margaret O'Donovan-Rossa of Staten Island, New York. He was the brother of Rossa Cole. His grandfather was the Irish Fenian leader Jeremiah O'Donovan Rossa. Cole worked in a deli and a bookstore in the 1930s.
After military service in the infantry in World War II from 1940 to 1945 (during which he earned a Purple Heart), he took various jobs in the publishing industry, serving as publicity director at Alfred A. Knopf from 1946 to 1958, publicity director and editor at Simon & Schuster from 1958 to 1961, and, with Viking Press, co-publisher of William Cole Books. He was also a prolific writer and anthologist, editing and writing over 75 books.
Many of his books were honored by the American Library Association, including I Went to the Animal Fair: A Book of Animal Poems (named a notable book of 1958, and on the List of Notable Children's Books of 1940–1959), Beastly Boys and Ghastly Girls: Poems (named a notable book of 1964), and The Birds and Beasts Were There: Animal Poems (honored in 1965).
Cole's whimsical poetry often appeared in Light Quarterly and was widely anthologized, as in The Oxford Book of American Light Verse and various collections by Willard R. Espy. Reviewing eleven collections of poetry for children, Selden Rodman (aided by his own three children) found Cole's Oh, How Silly!
