Sinclair was born in Baltimore, Maryland, to Upton Beall Sinclair Sr. and Priscilla Harden Sinclair. His father was a liquor salesman whose alcoholism shadowed his son's childhood. Priscilla Harden Sinclair was a strict Episcopalian who disliked alcohol, tea, and coffee. Both of Upton Sinclair's parents were of English ancestry, Paternal Grandparents were Scottish, and all of his ancestors emigrated to America from Great Britain during the late 1600s and early 1700s. As a child, Sinclair slept either on sofas or cross-ways on his parents' bed. When his father was out for the night, he would sleep in the bed with his mother. His mother's family was very affluent: her parents were very prosperous in Baltimore, and her sister married a millionaire. Sinclair had wealthy maternal grandparents with whom he often stayed. This gave him insight into how both the rich and the poor lived during the late 19th century. Living in two social settings affected him and greatly influenced his books. Upton Beall Sinclair, Sr., was from a highly respected family in the South, but the family was financially ruined by the Civil War, disruptions of the labor system during the Reconstruction era, and an extended agricultural depression.
