DuPont Deepwater factory site, aerial photograph. This view looks north-west over the Deepwater Point site, located in New Jersey, USA, on the eastern bank of the Delaware River. The site was acquired by the DuPont Company in 1914. Towards the end of World War I, it was developed into a dye factory and research centre under Arthur Chambers, named for him and chemist Oscar Jackson. It was here that new synthetic dyes, the fuel additive tetraethyl lead (TEL), aerosol propellent Freon, and the coating Teflon were developed or produced. The Deepwater Canal is at left. Photographed on 4 February 1935.
