NEW YORK, NY – Doyle's auction of Rare Books, Autographs & Maps on April 16, 2026 saw international competition drive strong results throughout the sale and a total that surpassed expectations.
Thomas Jefferson Letter on Toussaint Louverture
Highlighting the sale was a fascinating 1802 letter from Thomas Jefferson as president to Maryland Governor John Francis Mercer that achieved a strong $32,000. The remarkable letter captures a rare, candid moment in which Jefferson assesses, with striking clarity, the arrest of Toussaint Louverture, a leader of the Haitian Revolution, by French General Charles LeClerc, Napoleon’s brother-in-law. Jefferson perceptively warned that LeClerc’s actions would erode trust and likely spark further racial conflict—an insight that proved remarkably accurate. Beyond its sharp political foresight, the letter reflects the broader anxiety the Haitian Revolution provoked in the United States, which contributed to decades of diplomatic isolation of Haiti.
