James Scrymser founded the company in 1881. A history of Guantanamo Bay records its renaming as All America Cables, Incorporated on 15 February 1920 and All America Cables and Radio, Incorporated on 22 August 1938. That account calls the predecessor Central and South American Cable Company; Rosanoski suggests Telegraph was intended.
