Broom, Jacob (1752-1810), a farmer and businessman from Delaware, was a signer of the Constitution of the United States. He regularly attended sessions of the Constitutional Convention of 1787, but did not play a significant role.
Broom was born in Wilmington, Del. His business pursuits included banking, surveying, shipping, and the manufacture and repair of machinery. A cotton factory that he owned on the Brandywine River near Wilmington was one of the first of its kind in the United States. Broom became assistant burgess (legislator) of Wilmington in 1776. He was appointed chief burgess four times. Broom served in the Delaware state legislature from 1784 to 1786 and in 1788. In 1790, he became the first postmaster of Wilmington. Broom held this position until 1792. He died on April 25, 1810.
