== Early life == Warren was born in 1817 in Grafton, Massachusetts.
== Career == In the 1850s, Warren began working for his father's Boston-based rag business, when nearly all paper was made from rags. With an increase in the need for paper, not least from the government during the American Civil War, the rag trade dwindled significantly. In 1853, Warren opened his first paper mill, the S. D. Warren Paper Mill, on the Presumpscot River in today's Westbrook, Maine. Recognizing the importance of wood pulp, Warren purchased the Forest Paper Company in Yarmouth in 1873.<ref>''Discover Maine: Midcoast & Casco Bay'', volume 34, issue 5 (2025), p. 11</ref>
