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.
