Joseph Francis Sinnott (1837–1906) was an Irish businessman who emigrated to Pennsylvania in 1854. After thirty-two years with John Gibson's, Son and Co distillery, Sinnott became the sole proprietor in 1888. The renamed Moore & Sinnott was known as the largest distiller of rye whiskey in the US with the capacity to produce 30,000 barrels per year. As a prominent Philadelphia businessman, Sinnott also became a trustee of the Philadelphia and Reading Railroad and served as director of the First National Bank. At the time of his death, his estate was valued at 2.2 million dollars. His former home, the Joseph Sinnott Mansion, was added to the National Register of Historic Places in 1980. It is now part of the campus of Rosemont College.
