John Randel Jr.

John Randel Jr. (1787–1865) was an American surveyor, cartographer, civil engineer and inventor from Albany, New York who completed a full survey of Manhattan Island from 1808 to 1817, in service of the creation of the Commissioners' Plan of 1811, which determined that New York City – which consisted at the time of only Manhattan – would in the future be laid out in a rectilinear grid of streets.

Randel is also noted for having received one of the largest awards at the time as a result of his breach of contract lawsuit against the Chesapeake & Delaware Canal Company. The company's appeals of the judgment went to the United States Supreme Court, which affirmed the award, as well as Randel's right to directly receive canal tolls in order to collect it.
