From 1870 to 1875, Edison worked out of Newark, New Jersey, where he developed telegraph-related products for both Western Union Telegraph Company (then the industry leader) and its rivals. Edisonâs mother died in 1871, and that same year he married 16-year-old Mary Stillwell. Despite his prolific telegraph work, Edison encountered financial difficulties by late 1875, but with the help of his father was able to build a laboratory and machine shop in Menlo Park, New Jersey, 12 miles south of Newark.
