Zephaniah Platt (May 27, 1735 – September 12, 1807) was an American politician and lawyer, and founder of the U.S. town of Plattsburgh, New York.[1]
Platt was born in Huntington, Province of New York, to Zephaniah Platt (1705-1778).[1] He was a direct descendant of Richard Platt (1603–1684), who was born in Ware, Hertfordshire, England, and settled in the Connecticut Colony.
Platt received an English education.[2]
Zephaniah Platt practiced law in Poughkeepsie, New York, and was a member of the New York Provincial Congress (1775–1777),[3] Committee of Safety (1777), State Senate (1777–1783), Congress of the Confederation (1785 and 1786), Council of Appointment (1778 and 1781). He was a Dutchess County judge from 1781 to 1795 and delegate to the New York Constitutional Convention in 1788.[4] [5]
In 1788, he founded the town of Plattsburgh in New York, and moved there in 1798 to continue practicing law.[6] He was an originator of the Erie Canal, and was a regent of the University of the State of New York from 1791 until his death, in Plattsburgh, in 1807.[1]
Platt was married twice, first to Mary Hannah Davis (1741–1761) in 1756 and had two children:[1]
In 1761, he married Mary Van Wyck Platt (1742–1809) and had 12 children including:[1]

Platt's grandson (son of Jonas Platt) Zephaniah Platt (1796–1871) was Michigan Attorney General.[2]
