Peter Stephen Duval (1804/5 - 1886) was a prominent Philadelphia lithographer. He immigrated to Philadelphia from France in 1831 to take a job as a lithographer at the Philadelphia firm owned by Cephas Childs. In 1837, Childs retired and Duval took over the business. Over the course of the next thirty years, Duval would have several business partners and in 1857 his son Steven C. Duval joined the business. Peter Duval retired in 1869 but continued to be involved in his company until his death in 1886.
