James Greenleaf
James Greenleaf (June 9, 1765 – September 17, 1843) was a late 18th and early 19th century American land speculator responsible for the development of Washington, D.C., after the city was designated as the nation's capital following passage of the Residence Act in 1790. A member of a prominent and wealthy Boston family, he married a Dutch noblewoman, who he later abandoned and then divorced, and served briefly as consul at the United States embassy in Amsterdam. After his return to the United States, Greenleaf engaged in land speculation in Washington, D.C., New York state, and other areas. His land business collapsed in 1797, and he spent a year in debtor's prison. He married a wealthy Pennsylvania heiress after his release, and spent the remainder of his life in genteel poverty, fending off lawsuits.
