Francis Julius LeMoyne (September 4, 1798 – October 14, 1879) was a 19th-century American medical doctor and philanthropist from Washington, Pennsylvania. Responsible for creating the first crematory in the United States, he was also an abolitionist, founder of Washington's first public library (known as Citizen's Library), co-founder of the Washington Female Seminary, and an instrumental benefactor to the LeMoyne Normal and Commercial School (now LeMoyne-Owen College), to which he made a $20,000 donation in 1870.
