Sydney Lewis (October 24, 1919 – March 12, 1999) was a prominent Virginia businessman, philanthropist, and art collector.
Born in Richmond, Virginia, he was the founder of Best Products Co. (now defunct). He is the namesake of Lewis Hall at the Washington and Lee University School of Law, whose construction he and his wife, Frances, funded in 1976. Lewis himself held his B.A. from Washington and Lee (1940), and though he began the study of law, never received a law degree from Washington and Lee University as his legal education was interrupted by World War II. Subsequently he finished his JD degree at George Washington University in Washington DC. He practiced law for a brief period prior to entering his father's business, eventually to become Best Products Co. He and his wife, Frances, were awarded the National Medal of Arts in 1987.
