John Alsop (1724 – November 22, 1794) was an American merchant and politician from New York City during the American Revolution. He was a delegate for New York to the Continental Congress from 1774 to 1776.
Early life and career 
John Alsop, born in 1724 in New Windsor, Orange County, New York. He was the son of John Alsop, Sr., a lawyer first of New Windsor, New York, where he was largely interested in real estate. A few years later he removed to New York City and there practiced his profession for many years. He was a son of Capt. Richard Alsop and Hannah Underhill (December 2, 1666 – August 23, 1757) the daughter of Captain John Underhill (c. 1609 – September 21, 1672) and Elizabeth Feake, who was the daughter of Lt. Robert Feake and Elizabeth Fones.
Captain Richard Alsop first settled in New York during the 1650s. He had served as a major in Oliver Cromwell's army, but after a disagreement with the Lord Protector, he fled to the obscurity of colonial life.
John's mother was Abigail Sackett, 1695–1752, the daughter of Captain Joseph Sackett and Elizabeth Betts, the daughter of Capt. Richard Betts and Joanna Chamberlayne She married John Alsop, Sr. in 1718 and they were the parents of four children.
As a young man he moved to New York City and entered the mercantile world with his brother Richard. The brothers became importers and merchants in cloth and dry goods. Their enterprise prospered, and the Alsops, for several generations, became one of the great merchant houses of the city. With the business secure, John became interested in civic and political activities. He was elected by New York County to serve in the Province of New York Assembly. He was one of the civic leaders that incorporated the New York Hospital Association, and served as its first governor from 1770 to 1784.
He married on June 6, 1766 at New York City, Mary Frogat (1744 – April 14, 1772). They were the parents of one daughter, Mary who was born in New York on October 17, 1769 and died in Jamaica, New York on June 5, 1819. She was also a great niece of Governor John Winthrop of the Massachusetts Bay Colony.
Mary Alsop married Rufus King in New York City on March 30, 1786, he being at that time a delegate from Massachusetts to the Continental Congress then sitting in that city. Mrs. King was a lady of remarkable beauty, gentle and gracious manners, and well-cultivated mind.
Their nephew was Richard Alsop, one of The Hartford Wits (also called the Connecticut Wits) who were a group of American writers centered around Yale University and flourished in the 1780s and 1790s.
The revolution 
During the first phases of the American Revolution, the Province of New York Assembly could not reach a conclusion about the Continental Congress. As a result, delegates were selected by the revolutionary committees in each county. In 1774, John Alsop, along with James Duane, John Jay, Philip Livingston, and Isaac Low were named by several counties, extending from Long Island to Albany. When the Congress convened on September 5, it accepted these credential when John Jay presented them. Alsop wasn't able to attend until he arrived in Philadelphia on September 14.
As the revolution escalated in 1775, John Alsop was one of the leaders of the Committee of Sixty which became the provisional government in New York City. He actively supported the non-importation agreements that he had signed the previous October in the Congress, despite the costs to his business. He was active in recruiting militia and in efforts to equip and arm them. As the Assembly continued to refuse to recognize the national Congress, he was elected to the alternative revolutionary New York Provincial Congress, and they in turn returned him to the second Continental Congress.
1776 was a critical year in the struggle for New York. Alsop began the year at Philadelphia, in a session of Congress. He made several trips between there and New York, acting as an agent of congress through his business to acquire supplies, and particularly powder for the Continental Army. After General Washington visited Congress in late May, Alsop returned with him to New York in early June. He added efforts to find housing for 8,000 Continental Army troops to his earlier and continuing work on the supply problems. When his home in Newtown was captured by the British in August, he kept working from Manhattan. By September the British had occupied Manhattan as well, ending his effective contributions to the revolution. He escaped to Middletown, Connecticut and remained until the British occupation ended in 1783.
Later years 
After the war he worked to help rebuild the family business, and again became active as a civic leader. He was president of New York City's Chamber of Commerce in 1784 and 1785. He died at his home in Newtown, Queens County, New York on November 22, 1794 and is buried in Trinity Church Cemetery on Manhattan.
