Theodore Burr

Theodore Burr

Theodore Burr (16 August 1771 - 1822 [or November, 1824] ) was an inventor from Torringford, Connecticut credited with the Burr Arch Truss bridge design and cousin of vice president Aaron Burr.

Around 1804, Burr built the first "sizable bridge" crossing New York's Hudson River, near Watertown, New York.

Between 1811 and 1818, Burr designed, then constructed or supervised, five crossings of the Susquehanna River. The first four were in Pennsylvania at Nescopeck Falls (Berwick), Columbia, Harrisburg, and Northumberland. The last was the 4,170 foot (1271 m) Susquehanna River Bridge near Port Deposit, Maryland.

Burr was awarded US Patent No. [http://patimg2.uspto.gov/.piw?Docid=X0002769&idkey=NONE 2769] on April 4 1817 for his arch and truss bridge design.
