This excerpt from Ron Chernow's Alexander Hamilton provides a brief sketch of the Founding Father and his legacy.

Hamilton was the supreme double threat among the founding fathers, at once thinker and doer, sparkling theoretician and masterful executive. He and James Madison were the prime movers behind the summoning of the Constitutional Convention and the chief authors of that classic gloss on the national charter, The Federalist, which Hamilton supervised. As the first treasury secretary and principal architect of the new government, Hamilton took constitutional principles and infused them with expansive life, turning abstractions into institutional realities. He had a pragmatic mind that minted comprehensive programs. In contriving the smoothly running machinery of a modern nation-state—including a budget system, a funded debt, a tax system, a central bank, a customs service, and a coast guard—and justifying them in some of America’s most influential state papers, he set a high-water mark for administrative competence that has never been equaled. If Jefferson provided the essential poetry of American political discourse, Hamilton established the prose of American statecraft. No other founder articulated such a clear and prescient vision of America’s future political, military, and economic strength or crafted such ingenious mechanisms to bind the nation together.

Hamilton’s crowded years as treasury secretary scarcely exhaust the epic story of his short life, which was stuffed with high drama. From his illegitimate birth on Nevis to his bloody downfall in Weehawken, Hamilton’s life was so tumultuous that only an audacious novelist could have dreamed it up. He embodied an enduring archetype: the obscure immigrant who comes to America, re-creates himself, and succeeds despite a lack of proper birth and breeding. The saga of his metamorphosis from an anguished clerk on St. Croix to the reigning presence in George Washington’s cabinet offers both a gripping personal story and a panoramic view of the formative years of the republic. Except for Washington, nobody stood closer to the center of American politics from 1776 to 1800 or cropped up at more turning points. More than anyone else, the omnipresent Hamilton galvanized, inspired, and scandalized the newborn nation, serving as the flash point for pent-up conflicts of class, geography, race, religion, and ideology. His contemporaries often seemed defined by how they reacted to the political gauntlets that he threw down repeatedly with such defiant panache.

Hamilton was an exuberant genius who performed at a fiendish pace and must have produced the maximum number of words that a human being can scratch out in forty-nine years. If promiscuous with his political opinions, however, he was famously reticent about his private life, especially his squalid Caribbean boyhood. No other founder had to grapple with such shame and misery, and his early years have remained wrapped in more mystery than those of any other major American statesman, While not scanting his vibrant intellectual life, I have tried to gather anecdotal material that will bring this cerebral man to life as both a public and a private figure. Charming and impetuous, romantic and witty, dashing and headstrong, Hamilton offers the biographer an irresistible psychological study. For all his superlative mental gifts, he was afflicted with a touchy ego that made him querulous and fatally combative. He never outgrew the stigma of his illegitimacy, and his exquisite tact often gave way to egregious failures of judgement that left even his keenest admirers aghast. If capable of numerous close friendships, he also entered into titanic feuds with Jefferson, Madison, Adams, Monroe, and Burr.

The magnitude of Hamilton’s feats as treasury secretary has overshadowed many other facets of his life: clerk, college student, youthful poet, essayist, artillery captain, wartime adjutant to Washington, battlefield hero, congressman, abolitionist, Bank of New York founder, state assemblyman, member of the Constitutional Convention and New York Ratifying Convention, orator, lawyer, polemicist, educator, patron saint of the New-York Evening Post, foreign-policy theorist, and major general in the army. Boldly uncompromising, he served as catalyst for the emergence of the first political parties and as the intellectual fountain head for one of them, the Federalists. He was a pivotal force in four consecutive presidential elections and defined much of America’s political agenda during the Washington and Adams administrations, leaving copious commentary on virtually every salient issue of the day.
