Although Robert R. Livingston was not one of those who signed the Declaration of Independence, yet his name should ever be inseparably connected with theirs, for he was one of the committee of the immortal Congress of 1776, to which was intrusted the momentous task of framing that revered document. With such considerations, we have deemed it our duty to append the memoir of that great man, to the biographies of his colleagues in the National Council whence emanated that Declaratory Act which gave birth and freedom to a great nation.
From: B. J. Lossing, Signers of the Declaration of Independence, George F. Cooledge & Brother: New York (1848) [reprinted in Lives of the Signers of the Declaration of Independence, WallBuilder Press: Aledo, Texas (1995)], pages 243:
Chancellor Livingston continued actively engaged in public life until a year or so before his death, which occurred at his country-seat at Clermont, on the twenty-sixth day of February, 1813, when he was in the sixty-sixth year of his age. He was a prominent actor in scenes which present features of the most remarkable kind, as influencing the destinies of the world. His pen, like his oratory, was chaste and classical; and the laatter, because of its purity and ease, obtained for him from the lips of Doctor Franklin [i.e., Benjamin Franklin], the title of the "Cicero of America." And to all of his eminent virtues and attainments he added that of a sincere and devoted Christian, the crowning attribute in the character of a good and great man.
