Hamilton's great coalition, intended to work such wonders, boasted many brilliant names. Of the younger men Robert Troup, of Hamilton's age, an early friend of Burr, took a most conspicuous part, while among the older members of this galaxy was James Duane, a lawyer of rare ability, the first mayor of New York, for ten years continuously in the Continental Congress, a man of great force, of large wealth, and superb character. He was in his forties when Hamilton, a boy of seventeen, won his heart by a single speech, denouncing the act of Parliament which closed the port of Boston. The most notable man in the coalition, next to Hamilton and Jay, was Robert R. Livingston, now Hamilton's devoted friend, before long to be his bitter enemy. He was still young, little more than forty, but in everything he was bold and skilful, vigorous as a writer, eloquent as a speaker, deeply learned as a jurist, and rich in scholarship. Of the same age as Livingston was William Duer,[51] who started at eighteen as an aide to Lord Clive in India. Duer was at one time the most useful man in America. Nobody could cheat him. As soon as Hamilton became secretary of the treasury, he made Duer assistant secretary, an office which he held with credit until 1790, when he resigned to become the chief of a ring of speculators, who, two years later, left him insolvent and in jail. Hamilton's coalition also furnished the only instance of the political association of himself and Burr, although Burr's support of Yates is said to have been personal rather than political. The story is that Burr, seeking admission to the bar after reading law less than a year, induced Judge Yates to suspend the rule requiring three years of study, because of the applicant's term as a soldier, a service that laid the foundation of a lasting friendship.
