Oscar Williams (December 29, 1900 – October 10, 1964) was an American anthologist and poet. Oscar Williams was his pen name. He was born Oscar Kaplan in Letychiv, Ukraine, son of Jewish parents Mouzya Kaplan and Chana Rapoport. He immigrated to New York at the age of 7. Among his influential anthologies are Master Poems of the English Language, Immortal Poems of the English Language, The Pocket Book of Modern Verse, and the Little Treasury Poetry Series, which were used in colleges and high schools around the U.S. in the 1950s and 1960s. During his lifetime, anthologies he edited sold more than two million copies, a nearly unheard amount for books of poetry. Many of his anthologies are still being republished today. Though a friend and promoter of poets like Dylan Thomas and George Barker, Williams' own poetry is not highly regarded by critics, though he published several volumes during his lifetime, and is not nearly as accomplished as the poetry of his wife, Gene Derwood (1909–1954). Among Williams' poems are "Revenge," "Poem," "Poet," "The Last Supper" and "I Sing an Old Song," "The City's Face".
