The Marquis de Lafayette was entertained by the village of Poughkeepsie. En route to Staatsburgh to visit his Revolutionary War comrade-in-arms, General Morgan Lewis, Lafayette arrived by boat at 2:30 in the morning.  The village trustees, including Matthew Vassar, greeted him at the Forbus Hotel on Cannon Street, after which was entertained at breakfast at the Poughkeepsie Hotel by some 60 people—including the Founder—before continuing to Lewis's estate on the Hudson.  Edmund Platt, The Eagle's History of Poughkeepsie from the Earliest Settlements 1683 to 1905.
