Charles Reznikoff (1894 - 1976) was the son of Russian Jewish immigrants. He obtained a law degree but used it only to edit law books to support himself later in life. He was known as a proponent of Objectivism and helped establish the Objectivist Press. More details about his life may be found here:
The poem may have been untitled, as the first line and title are identical. It tells the poignant story of a boy who is unable to enjoy sledding down the street with the other children in his neighborhood because he is Jewish. The boy sneaks out at night when no one is around and enjoys sledding down the street twice.
