Hooper's Telegraph Works

The original core works were located at Mitcham, London with the later complete cable, core with external sheathing, production located and later consolidated at Millwall and the company renamed Hooper's Telegraph Works.

[4] The company's first large submarine cable order was from Great Northern Telegraph Company for a 2,300 nmi (2,600 mi; 4,300 km) nautical mile cable linking Vladivostok with Hong Kong, via Shanghai.

Hooper's rubber goods factory had previously been contracted by the Indian government to produce 12 nmi (14 mi; 22 km) of insulated cable and another contract producing cable to link India and Ceylon.

Menier filed against Baron de Mauá and Hooper's Telegraph Works for its profits from those dealings.

His suit was successful and the actions of Hooper's Telegraph Workswere found to amount to blatant and fraudulent appropriation of property.
